STM32CubeProgrammer on timeout for STM32MP1

[DMårt]

I have made my own STM32MP1 board with the STM32MP151AAC3 processor. Right now I'm faceing issues with the software STM32CubeProgrammer and I don't know why this happens.

My goal is to flash the eMMC via the UBS OTG. I have SDIO2 as eMMC by the way.

What we can see here is that:

• The STM32CubeProgrammer regonize the STM32MP1 processor and its name
• The USB OTG of the STM32MP1 processor is working
• I'm using the OpenSTLinux for STM32MP157 processor because it's the only one that are avaiable as Starter Package . It's only a minor difference between STM32MP151, STM32MP153(CAN FD) and STM32MP157(CAN FD + DSI)
• The flashing fails on 0x1 fsbl-boot
• The STM32CubeProgrammer can recognize the partisions when I connect via USB OTG

So the question is simple:

Why does STM32CubeProgrammer get timeout?

I understand. If you don't know more than I do about building own Linux OS for my HW. Then I'm on my own.

Thank you by the way for the answers. They have been very helpful. 

I think I will change the pin configuration inside TF-A and recompile it. It must be the only way. 

Perhaps Buildroot can compile everything for me at once? I have tried Buildroot before and compile. I did not know what I got back after the compilation. But I did get any errors.

Is it possible to flash a Buildroot compilation with CubeProgrammer?

Hi,

The flashing is usually the latest and the easiest step (if the binaries are running well as flashing is done using TF-A + uBoot tailored for your board).

Yes, either BuildRoot or Yocto could be used to generate binaires (there is more than one, see Flashlayout).

Once first clean compilation is achieved (mean all the environnement are ok), the most complex task is usually to have the correct Device tree for your own board. I encourage you to generate some with CubeMx/CubeIDE and diff with a working one from EV1 or DK1 board in order to get a custom one without forgetting anything (as Cubemx only generate 'partial' DT).

For Yocto, see https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package

for BuildRoot, you should check to our partner site https://bootlin.com/blog/building-a-linux-system-for-the-stm32mp1-basic-system/

Ok. I will give Buildroot another chance again.

As I understand. CubeIDE cannot be used to generate a device tree. CubeIDE is only made for barebone programming. Or do you mean that the CubeIDE should generate the .tvs files?

When I compiled Buildroot, I did not see any options how to generate .tvs files and all other files so I can upload them with CubeProgrammer. That's why I got stuck with Buildroot.

Because with CubeProgrammer. If I'm going to flash the eMMC and the CPU with CubeProgramer, I need to have .tvs files, .bin files etc. Just as the Stater Pack.

But right know, we know that I have wrong I2C configuration. I need to change the I2C pins from PZ4/PZ5 to PF14/PF15 becore I compile.

Update:

I now understand that Buildroot is NOT a tool for flashing the firmware. It's a tool for build a complete OS. 

What I need to do first, is to flash the CPU with the TF-A and TF-A need to have correct pin configuration.

[DMårt]

Do you think this number has to do with PZ4 and PZ5 pins? If I change this base address to another base address for the PF14 and PF15 pins. This might work? @PatrickF

Hi @PatrickF 

I found out that the STM32CubeIDE is generating .dts in the DeviceTree folder.

STM32-Computer/STM32CubeIDE/STM32-Computer/CA7/DeviceTree/STM32-Computer at main · DanielMartensson/STM32-Computer (github.com)

So right now I'm compiling the Linux kernel. I'm right here now:

https://github.com/STMicroelectronics/meta-st-stm32mp/blob/1f152e07019dc06fd331b4926ec7e76ceae3d259/recipes-kernel/linux/linux-stm32mp/README.HOW_TO.txt#L203

I have placed the file "stm32mp151a-stm32-computer-mx.dts" from the kernel folder, and paste it inside <linux source>/arch/arm/boot/dts folder.
