How do I flash OpenSTLinux onto STM32MP151 with eMMC by using STM32CubeProgrammer?

[DMårt]

I have built my own STM32MP15XXAC board from scratch DanielMartensson/STM32-Computer: STM32 Computer were Linux can be deployed onto (github.com)

Instead of SD-card, it has eMMC. Now I want to flash the eMMC with OpenSTLinux. How can I do that with STM32CubeProgrammer?

I find lack of information how to install Linux or other kind of Linux-OS onto eMMC for STM32MP15XXAC.

Hi @DMårt ,

It works in the same way as with an SD card, you just have to be sure that the file you're sending is for emmc.

Thank you for your reply.

But where do I start?

I have downloaded the software STM32CubeProgrammer. So now I need some image right or firmware? Where can I find that?

You can adapt the ostl to your physical characteristics, using either 

• the distribution package to use Yocto  : https://wiki.st.com/stm32mpu/wiki/STM32MPU_Distribution_Package
• the developer package to use the SDK : https://wiki.st.com/stm32mpu/wiki/STM32MPU_Developer_Package 

Then follow this example to flash your EMMC : https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-EV1/Let%27s_start/Populate_the_target_and_boot_the_image

Hi!

There is no pre-compiled OS image? 

Compile the linux kernel for this processor can take weeks.

Now I have flashed the board. Is this correct?

I did not get any pop-up that saying "Flash complete"

Hi @DMårt ,

There is no pre-compiled OS image? 

We have a starter package, but it may not work with your hardware.

Now I have flashed the board. Is this correct?

If you've followed the steps in the starter package, it should work.
If you don't get a message, your eMMC was not flashed correctly, and as I said above, this is probably due to your hardware modification.

Hi! I get an error message now.

I don't know if the eMMC is broken, not soldered correctly or the software is not suitable for the hardware. 

The problem with buildning own linux, is that most of the configurations gave me errors. 

Update:

I notice that the eMMC was not correctly soldered. I did a reflow with my air heating gun and saw that the eMMC become much more flat because it was tilting some 0.05mm i Z-axis. So I reflowed it and move it a little bit with a tweezer and it sure looks like it fits the pads. 

So it must definitely be a software issue. I reflashed the eMMC with STM32CubeProgrammer and I got the same error as below.

Hi @DMårt ,

I see you create a new post for this issue ( https://community.st.com/t5/stm32-mpus-embedded-software/stm32cubeprogrammer-on-timeout-for-stm32mp1/td-p/699791 ) and you've already had some answers. So I'll let you continue with this other post.
