Need Help Flashing STM32MP15xx, Repeat Partition 0x01 Flashing Issue

[Pablo89]

Hi,

I'm currently facing an issue while trying to flash my STM32MP157C using STM32CubeProgrammer (CLI) with a flash layout `.tsv` file. Every time I run the command, it seems to flash partition `0x01` successfully, but then it starts flashing the same partition again in an infinite loop.

Here’s the command I’m using:

STM32_Programmer_CLI -c port=usb1 -w flashlayout-demo.tsv

Output from STM32CubeProgrammer:

However, after this, the same file is flashed to partition `0x01` again, and this cycle repeats itself. Here’s a snippet of the output, showing the repeated operations:

Here is the content of the `flashlayout-demo.tsv` file I’m using:

#opt Id Name Type Device Offset Binary

- 0x03 fip-boot FIP none 0x00000000 fip-stm32mp157c-ev1-optee-emmc.bin

My Questions:

1. Why is the STM32CubeProgrammer repeatedly flashing partition `0x01` even after the "Start operation done successfully" message?
2. Is there an issue with my `.tsv` file or the flashing procedure?
3. How can I stop this endless flashing loop and ensure the correct partitions are flashed as per the layout?

Any advice or guidance would be greatly appreciated. Thanks in advance for your help!

Hi,

should work.

Please confirm you are using an STM32MP157x-EV1 board.

Please confirm there is 'tab' separators in the .tsv file.

Could you please share the board console output messages during the flashload (using ST-Link connector of the daughter board and VCP terminal on the PC) ?
Is it working when you do a complete starter package flashload with provided .tsv as described in https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-EV1/Let%27s_start/Populate_the_target_and_boot_the_image ?

Regards.
