Hello,

I developed my pcb with the OSD3358 are i having trouble starting the OSD3358.
In conversation with somebody of octavo systems:
1. What error are you seeing when you’re trying to boot your board?
2. What specific OSD3358 do you have in your board (i.e., OSD3358-512M-BAS (27mm) or OSD3358-512M-BSM (21mm))?
3. Are you using a BeagleBone image to boot your board? Which image are you using?
4. How are you booting your PCB (i.e., USB, SD card, eMMC, etc.)?
5. Does the image that you’re using work in a standard BeagleBone (i.e, the BeagleBone Black wireless)?
1. Don’t detects Com Port
2. BAS
3. Debian 9.3 2018-01-28 (http://beagleboard.org/latest-images)
4. SD Card
5. Yes
The OSD need the EEPROM 24LC32AT-I/OT? And circuit configurator in attachment?

Somebody can help me?

David,

The Beagle images require the EEPROM programmed with a board ID in order for them to boot. See https://octavosystems.com/forums/topic/issues-booting-custom-board/#post-4608 for more information. You can also update your Beagle image with a new u-boot using the following procedure to bypass the EEPROM ID check:

– Create an SD card with the latest Beagle image or the image you want to use by following the procedure in https://beagleboard.org/getting-started

– In an Ubuntu machine or a VM that runs Ubuntu, download and compile u-boot:

1. Download the ARM cross-compiler GCC. Note the pwd in code line 3 needs a special character “`” on both sides
– wget -c https://releases.linaro.org/components/toolchain/binaries/6.4-2017.11/arm-linux-gnueabihf/gcc-linaro-6.4.1-2017.11-x86_64_arm-linux-gnueabihf.tar.xz
– tar xf gcc-linaro-6.4.1-2017.11-x86_64_arm-linux-gnueabihf.tar.xz
– export CC=`pwd`/gcc-linaro-6.4.1-2017.11-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

2. Download u-boot
– git clone https://github.com/u-boot/u-boot
– cd u-boot/
– git checkout v2018.01 -b tmp

3. Get the patches (Needs internet connection)
– wget -c https://rcn-ee.com/repos/git/u-boot-patches/v2018.01/0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch
– wget -c https://rcn-ee.com/repos/git/u-boot-patches/v2018.01/0002-U-Boot-BeagleBone-Cape-Manager.patch
– wget -c https://raw.githubusercontent.com/RobertCNelson/Bootloader-Builder/master/patches/v2018.03-rc1/0002-NFM-Production-eeprom-assume-device-is-BeagleBone-Bl.patch

4. Apply patches to u-boot
– patch -p1 < 0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch

– patch -p1 < 0002-U-Boot-BeagleBone-Cape-Manager.patch

– patch -p1 < 0002-NFM-Production-eeprom-assume-device-is-BeagleBone-Bl.patch

5. Configure and Build
– make ARCH=arm CROSS_COMPILE=${CC} distclean
– make ARCH=arm CROSS_COMPILE=${CC} am335x_evm_defconfig
– make ARCH=arm CROSS_COMPILE=${CC}

6. Attach the SD card to the computer and run ‘lsblk’ to find out the id of the SD card. In our case the id was ‘sdb’

7. Install bootloader:
– export DISK=/dev/sdb
– sudo dd if=./u-boot/MLO of=${DISK} count=1 seek=1 bs=128k
– sudo dd if=./u-boot/u-boot.img of=${DISK} count=2 seek=1 bs=384k

This installs a new version of u-boot that does not check the EEPROM. If you insert the SD card into the
board and power it up holding down boot button, you should be able to see the user LEDs light up.

Hope this helps.

Thanks,
Neeraj

Hi Neeraj,

We have some difficulties in section 5., some errors appeared.

” 5. Configure and Build

– make ARCH=arm CROSS_COMPILE=${CC} distclean

– make ARCH=arm CROSS_COMPILE=${CC} am335x_evm_defconfig

– make ARCH=arm CROSS_COMPILE=${CC}

”

But for now i have an issue that must have been forgotten or I did not realize

The octavo need the “configuration” circuit in the image in attach?

Thank you.

Hi David,

Please post the error you are seeing on step 5. Also, there was a small mistake (a br tag that was not supposed to be there) in step 4 which I have now corrected. Other than that, this procedure has been verified and tested by costumers. Here is the reference to the original wiki this procedure was formulated from: https://eewiki.net/display/linuxonarm/BeagleBone+Black

For the second question, Yes. The boot configuration is required to tell the processor about the boot mode (SD card, eMMC etc.) Please take a look at the tutorial series we put together that can help designing with the OSD335x: https://octavosystems.com/app_notes/osd335x-design-tutorial/

Hello Mr. Neeraj,

I have developed my custom board based on OSD3358 beaglebone black wireless version. I am attaching my circuit design png below.

Changes in my board:

different wireless module and instead of HDMI i am using LCD interface directly. All remaining things are exact of the octavo’s BBB.

Now current status of board is as follows :

EMMC is empty and i am not inserting sd card in slot.My intention is to go in UART boot mode and see “CCCC” coming on the serial monitor.

Power led,PMIC_LED_GOOD ,reset_signal all power voltage rails are working fine. currently I am unable to check crystals because of CRO unavailability.

Question : I am getting 0.60 volt on UART0_Tx debug header instead of 3.3 volts. I have checked buffer ic and all traces on pcb they all checked out. And resistance of trace is 4.5 OHM so that should be not an issue for fast signal like this. I am thinking it is because at power on boot lines aren’t getting latched! what are your thoughts on this?

Note : On pcb i have kept 47pF capacitors pads open(They are connected to BOOT lines/LCD lines). They are not populated, should i populate them??

Thank you,

Keval Desai

Hello kd,

I didn’t find anything on the schematic that would interfere with UART0 operation. Boot configuration seems to be fine. I don’t think absence of 47pF caps are causing problems either.

We will need a little more information before we proceed further.

1. What is the voltage on the UART0_TX line at the input of buffer U8?

2. Did you actually try connecting UART0 pins to a Serial Client like Putty? Were you able to see any messages?

Hi,

Thank you for coming to my aid,First of all I like to mention one thing which I forgot last time is, between poweronreset(cold reset) and nreset(warm reset) there is a buffer. We haven’t populated that buffer on Pcb due to unavailability of that ic on our end. But I don’t think that can cause any problems.

1) at the input of buffer U8 , it is 0.60 voltage. Same reflects on its output pin.

2)I am using pqcom in windows which perfectly works with original BBB. At 115200 baud rate. I tried to connect it but it didn’t show anything.

3) we have eeprom that Is not programmed so we have to bypass that check in uboot,my colleague is working on that as soon as he is done I will test to see if I get any status led working.

But I doubt that wont work until we solve this problem. It is something in hardware but I am unable to pinpoint it exactly.

What do you think,what should I do next?

Thank you,

It is my pleasure to help you. I believe the absence of buffer U5 is not the problem. We need to first find out if the processor is alive.

1. In the beginning of our discussion, you said “Power led,PMIC_LED_GOOD ,reset_signal all power voltage rails are working fine.” I’m not yet sure if you’ve already tested the voltages on the following test points (corresponding correct voltages are also given below):

VDDS_DDR: 1.5V

VDD_CORE: 1.1V

VDD_MPU: 1.1V

VDDS_PLL: 1.8V

By verifying the above voltages we can make sure that AM335x is receiving necessary voltages from PMIC during and after boot.

2. I believe you have already verified boot configuration resistors. Make sure all the resistors are properly populated and resistor values are correct.

3. If all the above two tests pass, use a JTAG cable and try to connect to AM335x using Code Composer Studio. OSD335x Bare Minimum Boot Process Article will help you setup Code Composer Studio and connect to OSD335x using a debugger.

If steps 1, 2 pass and JTAG test fails, I would strongly recommend getting a CRO and verifying if OSD335x is receiving proper clock input before debugging the hardware further.

After trying the above steps, I would also recommend going through AM335x Board Bring Up Tips Wiki.

I just found out the problem. i assumed that processor is working fine and focused on just uart signaling part and found out that i made a mistake in schematic.

If you follow my schematic properly you will find that due to my wrong labels of signals input/output of uart buffer ic got shorted out. I removed the UART buffer ic and now i am able to see “CCCC”on serial monitor.

Right now i am attaching FTDI cable directly to processor’s debugger without buffer ic. And its working fine. should i keep buffer ic between them?

I’m glad the problem is solved. The buffer IC is not mandatory.

Out of curiosity, I would like to know what exactly caused the short. I went back and looked at your schematic again. Your labels are NOT wrong. When 2OE is pulled high and *1OE is pulled low, the buffer IC (SN74LVC2G241) passes data from 2A (UART0_TX) to 2Y (B_UART0_TX) and from 1A(B_UART0_RX) to 1Y(UART0_RX). The pin to signal mapping of the buffer also seems to be correct on schematic. I’ll be glad if you could elaborate a bit more.

Actual connector is on left-top corner of the schematic. You will notice that , those pins have UART0_TX labeled, in the updated and final schematic i removed those extra small pins and routed only main big connector. So in the end B_UART0_TX got replaced with UART0_TX. You will find routing error in attached file.

I have one query left which is as follows

Right now i do not have EEPROM programmed and so when i boot readymade BBB images through SD card will it throw anything on serial debug? like MLO found and reading boot image etc… We haven’t provided bypass for the check of the eeprom in uboot. My intention here is to check sd card interface working properly or not!

  Thank you for the clarification.
  
  Readymade BBB Images will not throw anything on the Serial Debug interface if EEPROM is empty. It’ll be best if you could modify your existing BBB image to bypass EEPROM check.
  
  See response #4733 by Neeraj Dantu (part of same thread we’re currently discussing on) where he describes how to modify BBB image to bypass EEPROM check.
  
  Please let us know if you have any other queries.

Yes my team mate is currently working on that patch. Mine and my team mate’s understanding is EEPROM check happens in uboot spl stage. Before that MLO and uboot spl (starting ) log should be printed by UART console. But i am getting none when in SD card boot mode!!!

I am booting this image through SD Card :

  I understand your concern. Unfortunately, the U-Boot SPLs that are part of the newer BBB images don’t print anything on the UART console if EEPROM is empty.
  
  THERE IS A WORKAROUND FOR THIS. Debian 7.5 (Old version of BBB Image) DOES print U-Boot error message if EEPROM is empty. You can download it from:
  
  Debian 7.5 (BeagleBone, BeagleBone Black – 2GB SD) 2014-05-14
  
  I tested this image on a board with empty EEPROM. I have attached a picture of the U-Boot error message on UART console. You should get the same thing when you use it on your board.
  
  Hope this helps!

Hi, I just tested your suggested image and it is working as expected. It is throwing error message on uart which means sd card interface is working.

Thank you so much for your constant support.

@EshtaarthaAs i mentioned before i have blank EEPROM on my board so i tried following method to bypass the check.

@Neeraj First we tried this post #4733

It is part of this thread . in this process we face no difficulty while applying the patch and building the source. But when i boot image through sd card my board didn’t responded on uart debug terminal. We haven’t received anything on the uart console.

@EricT So second we tried this post #4582

We made a change in latest version of uboot available on github.

u-boot/board/ti/am335x/board.h
```
static inline int board_is_bone_lt(void)
{
        printf("called it\n");
        return 1;
}
```
And i dump this image on sd card and boot my custom board. it started throwing messages on serial uart as follows.
```

What do you think? is it a hardware problem? or uboot problem? i tested this image on real BBB which works fine.

My main objective here is to reach at the uboot console somehow. I dont know where exactly problem is happening!!!

  Based on the errors you’re getting, it looks like this is a device tree issue. I believe your hardware is behaving different from that of BeagleBone Black and hence Device Tree is having trouble loading drivers and initializing your hardware. It would be best if you modify the Device Trees of both your U-Boot and Kernel. You can use a Device Tree Rebuilder for this.
  
  You can just use a minimal device tree for verification.

HI,

Recently we tried resetting board several times with image which contains eeprom bypass check. And 1 in 5 try we were able to get into uboot console. at the end we realize we can not write eeprom because on our custom board i2c0’s SCL line is shorted to V3.3B. There is no way to remove that short.

other peripheral seems to be getting proper voltages without any pcb design fault. Do you think if we can properly bypass eeprom check in uboot we will be able to use our board as intended . We are not using i2c0 except on pmic/eeprom (by default). We haven’t tried booting a kernel yet. Do you think that is it possible if we properly work on uboot we can overcome this hardware fault?

  @kd
  
  Yes. You should be able to use the board as intended if you bypass EEPROM properly. Keep in mind that PMIC will always function in its default configuration and you won’t be able to configure it (changing input current limits etc) without I2C0.
  
  Since I don’t have access to your actual schematic file, it is difficult to track all signals with just a picture of your schematic. From what I see, it looks like I2C0_SCL is not shorted in schematic. Is it shorted in layout?

yes, it is shorted in layout. And i wont be able to remove it. Do you think default configuration will work ? i am aiming for processor, ddr, and sd card to work properly. i am able to get to the uboot console.

  Since you’re board is powering up and you’re able to reach U-Boot console, PMIC seems to be functioning properly. The default configuration of PMIC is sufficient for most applications (You can go through TPS65217C datasheet for more information). Yes, PMIC should be able to support all peripherals on BeagleBone Black in its default configuration (Processor, DDR3 and SD Card in your case).

Hi,

We received our custom boards with the OSD3358. I carefully followed the instructions described by Neeraj in post #4733 and having some issues getting the flasher image to flash the image to the emmc. I am using the “Debian 9.5 2018-10-07 4GB eMMC IoT Flasher” beagle image and followed all instructions without any errors. Now when I insert the sd card and power the board, the flashing process does not start nor the user LED’s light up. Below is the log I got from the serial console.

I have made some progress. I included the “v2019.04” branch and followed the same process. And I hardcoded board id as below:

// In ==> u-boot/board/ti/am335x/board.h

static inline int board_is_bone_lt(void)
{
	//return board_ti_is("A335BNLT");
	return 1;
}

Now, at least I can see the user LEDs flashing when booting up. But now the image flashing never initiates and system resets. I think I am very close to resolving this, below is the logs during boot over the serial console. It would be great if someone here could take a look at it to advise on how to proceed.

Hey Vinay,

Here are some inputs to resolve the issues:

1. Using the flasher image: The u-boot in the flasher image checks for the EEPROM ID in the EEPROM. If it doesn’t find a valid EEPROM ID, it will try to write a valid ID to the EEPROM and reset itself(reboot). So, the next time u-boot is loaded and executed, it should find the valid ID that was written the previous time. This however will not happen if EEPROM_WP(Write protect) pin is not grounded. The EEPROM_WP pin must be grounded in order to write anything to the EEPROM. Any write without this connection will fail, resulting in no EEPROM ID in the EEPROM and therefore an infinite loop u-boot.

2. Using the flashing script: From the log, this seems to be the same problem.
```
Checking for Valid bbb-eeprom header
==> Invalid EEPROM header detected
===> Writing header to EEPROM
0+1 records in
0+1 records out
27 bytes copied, 0.00524933 s, 5.1 kB/s
===> eeprom check: [\FF\FF\FF]
========================================
Failed to read reboot parameter file: No such file or directory
Rebooting.
```
If you connect the EEPROM_WP to GND, this should resolve both the issues.

Best,

Neeraj

  Hi Neeraj
  
  I am the hardware engineer who designed the circuits and PCB for this project. Our design has EEPROM_WP connected to LCD_DATA_4 as it was in the design that was validated by Martin at Octavo. Problem with this is we knew LCD_DATA_4 had to be tied high for the correct boot order which it is via a 100K resistor, we did not know the EEPROM_WP needed to be tied low during the boot process. We already have the boards and these are directly connected together on an internal PCB layer so disconnecting them is not a viable option, what you do you suggest as a sensible solution?

  Dman,
  
  The boot mode configuration on the LCD pins is only relevant at boot. You can use the LCD pins as GPIOs during u-boot to set that pin the LOW. This would allow the flasher script to program the EEPROM.
  
  You can also modify check_eeprom function in /opt/scripts/tools/eMMC/functions.sh to ignore the blank EEPROM. The function is called from /opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh script.
  
  Best,

Hi Neeraj,

In the init-eMMC-flasher-v3.sh script, I commented out the “check_eeprom” as shown below.
```
source $(dirname "$0")/functions.sh

#mke2fs -c
#Check the device for bad blocks before creating the file system.
#If this option is specified twice, then a slower read-write test is
#used instead of a fast read-only test.

mkfs_options=""
#mkfs_options="-c"
#mkfs_options="-cc"

device_eeprom="bbb-eeprom"

check_if_run_as_root

startup_message
prepare_environment

countdown 5
#check_eeprom
check_running_system
activate_cylon_leds
prepare_drive
```
And then I tried, the flashing process started along with the cyclic led flashing. Once all the led’s turned off after flashing,I removed the sd card and power cycled the board. But now I don’t see anything on the serial terminal, nor the user led’s start to flash. I again retried with the sd card inserted to check if anything prints in the terminal and flashing restarts, but nothing. Any insights on why this may be happening

Hi Neeraj,

We made the changes in the script as you suggested and now board boots and we are able to log in. Thanks.

I have same problems as you.

>>We made the changes in the script as you suggested and now board boots and we are able to log in

could you please tell me what do you change in script ?

  hswoo,
  
  Did you set the EEPROM WP pin to GND?
  
  Note that the flashed image would still check for the EEPROM ID. Please take a look at https://octavosystems.com/app_notes/osd335x-eeprom-during-boot/ to resolve the issues with EEPROM ID.
  
  For specific errors, please take a look at the output of the script or post it here to determine what is going wrong.
  
  Best,
