Need help on OSD335x-BAS boot

[allankliu]

We have a custom made OSD3358-BAS gateway. According to the BOOT pin configuration, the boot sequence should be eMMC/SD/USB/UART. We are trying to boot it with image from BBB and flash the internal eMMC.

bone-eMMC-flasher-debian-10.3-iot-armhf-2020-04-06-4gb.img.xz

we burn the image into a TFC and boot, we get the following log from UART. (which is also attached for this thread).

According to the log,

– System is boot from TFC (which is MMC0?)
– omap_hsmmc driver is missing
– /boot/uboot.env is missing
– MMC0/partition0 is active
– MMC1 has no partition
– USB0 not available
– musb-hdrc USB OTG is loaded
– USB Ethernet is detected

Then the system is keep waiting for remote access from ethernet…If we remove TFC, the UART keeps printing C, which means no OS at all.

I guess I should remotely log into Linux (boot from TFC) and mkfs for MMC1 (aka internal eMMC), then the sytem can flash the Linux into eMMC. However, I have no idea which methods(steps) I should follow at this moment.

Remote access via UART? or Ethernet? With password as debian and temppwd? I am appreciated if someone can help me about this boot issue. Thanks.

Allankliu,

It looks like U-Boot is reading the uEnv.txt file located in /boot folder and then something goes wrong. When using the [BLNK] EEPROM ID, Beagleboard images default to Beaglebone Black configuration. First, check if your board configuration is same as Beaglebone Black in regards to the pins used to the MMC interface to boot. Please note that you may have to recompile U-Boot and kernel device trees if you are not using the same pins for the boot media.

You can also stop the boot at U-Boot when it prompts you this message “Press SPACE to abort autoboot in 2 seconds”. You can then use mmc commands in U-Boot to check for presence or absence of MMC interfaces. Some of the commands available in U-Boot shell are shown here: https://sites.google.com/site/manisbutareed/bringing-my-beagles-to-heel/u-boot-commands.
