Hi,

A have a question related to this topic. Is possible to disable the signature of the modules through menuconfig disabling any option in the kernel? I have the same problem when enable drivers that are part of the kernel.

Thanks in advance.

To add more information I am compiling the driver out of tree with a Makefile, when it is compiled I send to my board and try to charge the driver with the insmod command, at this moment receive the message that says disagrees about version of symbol module_layout.

Hi,

I have never seen a signed kernel module, ¿Where Do I need to add this, in my Makefile?

Thanks in advance.

Finally I have obtained the the ST Link V2 and I have been able to load the program OpenAMP_TTY_echo that is mentioned in the tutorial. Now I want to write from the A7 to the Cortex M4 and generate a PWM signal, but my doubt is about the hardware configuration in the cortex M4. In the examples provided by ST to the board DK2 they define the pins related for example to the leds and the buttons. My doubt is the next, do I must define in the STM32CubeIDE project (in my case) the hardware that the Cortex M4 will use? Is there some information about this for the Octavo Boards? I have doubts about this, because by one side the hardware is defined yet in the device tree of my Linux image, so I don’t know how procede. Could you indicate me?

Thanks in advance.

Is it possible with a JTAG for example of Texas Instruments? I don’t find availability of the ST JTAGS. I think that is not possible with other JTAG but to be confirmed.

Thanks in advance.

Hi,

I have with the mentioned modification the same error.

[amolina]

Thanks for the reply. Currently I don’t have a STLink debugger, is not possible do the connection to the Cortex M4 without the STLink debugger?

I have seen that after modify the device tree I unable to generate the .dtb file with the device tree modifications, How can I generate this .dtb file with the modifications in the device tree?

Hi,

I haven’t achieved that the modifications works. Could you detailed more the instrucctions? Is neccesary that I execute the instructions the commands indicated here https://github.com/octavosystems/osd32mp1-build-tools? How do I compile the modifications?

Thanks in advance.

I have solved the problem, I could not use repo sync by a problem with python, so I was including layers that was not necessary. Thank you for the support, the problem was mine.

[amolina]

Now I obtain the next error, the previous is solved:

ERROR: Nothing PROVIDES ‘octavo-image-weston’. Close matches:
core-image-sato
core-image-weston
st-image-weston

I am obtaining the problem that appears in the image. Also I attach my local.conf file and my bblayers.conf.

Hi,

I have my own image developed in yocto that is custom-image, is it possible to generate this image with MACHINE = “stm32mp1” in local.conf and after add the hardware files? I have found this repository https://github.com/octavosystems/OSD32MP1-RED-Device-tree.
