STM32Prog CLI and OTP Disply

[Niklas Voi]

Hi,

i currently trying to interact via shellscript and stm32cubeprog cli with my stm32mp157 board.

I can run and load tfa and than uboot. But when i want to read otp, my operations get stuck.

What is the correct call for this?

In my Script is use the following :

.../STM32_Programmer_CLI --connect port=usb1 -tm 20000 serial --verbosity 1 -tm 5000 --write ./tfa_und_uboot_slow.tsv --go 0x03 -otp displ

This is my TSV:

#Opt Id Name Type IP Offset Binary

- 0x01 fsbl1-boot Binary none 0x0 ./tf-a-slow-usb.stm32

- 0x03 ssbl-boot Binary none 0x0 ./uboot-slow-usb.stm32

${PROGRAMMER_BINARY} --write ./tfa_und_uboot_slow.tsv --go 0x03 -otp displ

This is the output:

Hi,

please try:

.../STM32_Programmer_CLI -c port=usb1 -w ./tfa_und_uboot_slow.tsv -otp displ

Works with a similar command line on my STM32MP157F-DK2 board with a simple '2 binaries' TSV file as yours.

#Opt	Id	Name	Type	IP	Offset	Binary
-	0x01	fsbl1-boot	Binary	none	0x0	arm-trusted-firmware/tf-a-stm32mp157f-dk2-usb.stm32
-	0x03	fip-boot	Binary	none	0x0	fip/fip-stm32mp157f-dk2-trusted.bin

Ensure your board is in DFU mode (empty flash or BOOT pins=0b000).

If issues, please check board UART console log.

Are you sure that your TF-A and uBoot are working ?

Hi Patrick,

i tried, but no i get stucked in the TF-A:

Now i get the following Message:

WARNING: VDD unknown

INFO:  Reset reason (0x15):

INFO:   Power-on Reset (rst_por)

INFO:  Using USB

Also some tries later i get into uboot ( when i connect on UART4 )

There is following message:

RUNNING Program ... 

 PartID:   :0x03 

Reconnecting the device ...

On the console:

    scanning usb for storage devices... 0 Storage Device(s) found

Hi,

I think your TF-A and uBoot are not correctly setup regarding your custom HW.

May I suggest to look at following articles:

https://wiki.st.com/stm32mpu/wiki/How_to_configure_U-Boot_for_your_board

https://community.st.com/s/article/FAQ-STM32MP1-Bring-up-procedure

https://community.st.com/s/article/FAQ-STM32MP1-bring-up-troubleshooting-guide

note that if you use CubeProgrammer with UART instead of USB, you should also use a different TF-A binary than for USB (ending with ...uart.stm32 instead of ...usb.stm32).

See https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_flashlayout#Using_STM32Programmer_over_UART
