STM32MP157-DK2 problems flashing boot image using CubeProg and STM32_Programmer_CLI

[DigiCode]

Despite my best efforts to populate and boot the the image of the STM32MP157-DK2 using the .tsv files I am met with a mixed result To date I have yet to establish a USB connection despite following the procedures at wiki. The UART connection is working. My environment is as follows ...

Ubuntu 24.04.4 LTS - stm32mp1-openstlinux-6.6-yocto-scarthgap-mpu-v26.02.18 - STM32CubeProgrammer v2.22.0 and STM32_Programmer_CLI

 

Be it that I use STM32CubeProg or the STM32_Programmer_CLI terminal interface the FlashLayout_sdcard_stm32mp157f-dk2-optee.tsv is not found despite the path being correct. Yet I am able to flash tf-a-stm32mp157c-dk2-optee-programmer-usb.stm32 0x01 or tf-a-stm32mp157f-dk2-optee-programmer-usb.stm32 0x01 using the terminal which was the first value in a sequence of the .tsv file (see kate as an example). The same conundrum occurs using STM32CubeProg. Might you suggest how I might resolve this problem - be it in establishing a USB connection or flashing the sd card using a different approach? Thanks in advance for your assistance. Much appreciated.

Hi @DigiCode 

I'm on windows, but command line should be similar on Linux.
I'm using the following, run from the folder "...\stm32mp1-openstlinux-6.6-yocto-scarthgap-mpu-vxx.xx.xx\images\stm32mp1\"

"%ProgramFiles%\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" -c port=usb1 -w flashlayout_st-image-weston\optee\FlashLayout_sdcard_stm32mp157f-dk2-optee.tsv

 

in case of issue, please BOOT pins and also check UART console log for potential error messages (could be due to supply not USB-C compliant).

Patrick thanks for your response. I had previously followed the link that you provided to no avail - since then I have corrected the paths to the values within the .tsv files and I am now working towards the inspection of the UART log files. Regardless I have a question?  In adjusting the paths within the .tsv am I screwing up a structure that is causing timeout errors?

On another note: the naming convention of the files at this end do differ so in changing them to match the files as this end does that ripple through and cause bigger problems? Perhaps I need to adjust the baud rate? It does not appear to be a power supply problem. Regards.

Hi @DigiCode 

I forgot to notice that you were trying to download using UART. This is not supported for whole package, only for debug purposes (e.g. to load small bare-metal test program).
Please use USB (CN7 to connect to the PC as USB DFU). STLINK port is only for UART console (VCP) or debug.

In the CLI command line, use the "port=<DEVICE_PORT_LOCATION>" with the USB one:

Hi Patrick,

please provide a part number for the USB-C compliant power supply (5V 3A) that is recommended by ST? The power supply at wiki.st.com is European and appears to be the gold standard of a Raspberry Pi. At this end I will require a North American version. FWIW DigiKey offers the SC1412 and a separate North American adapter PWREU-US. Is this the P/S that ST recommends?? My St-Link is now connecting, but it too times out??? My preference would be to forego the use of a North American adapter.

Thanks in advance for your assistance.
