How to program OTP on STM32MP1

[Dat Tran]

I followed ST wiki, success to display OTP by the command:

STM32_Programmer_CLI.exe --connect port=usb1 -otp displ

Then I try to test writing a value to wordid 79 which currently is 0x00000000, and free for user.

STM32_Programmer_CLI -c port=usb1 -otp program wordID=0x4F value=0x12345678

No thing wrong, command return sucess:

 

I display cmd again, it is till 0x00000000, even reset the board.

 Any one know what I am missing, please?

https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_OTP_management#Examples_with_STM32Programmer

Do you use OpenSTLinux DV4.0.1 (header v2)?

With a minimal flashlayout + otp displ, it should work to write and readback OTPs, ex for a MP157 DK2 board.

./STM32_Programmer_CLI -c port=usb1 -w FlashLayout_stm32mp157c-dk2.tsv

./STM32_Programmer_CLI -c port=usb1 -otp displ

Hi @OlivierK​ 

I follow steps from here:

 

The SDK I downloaded just last week.

The board is STM32MP157F-DK2 - Discovery kit with STM32MP157F MPU - STMicroelectronics

[Dat Tran]

And I ran STM32CubeProgrammer on win10, does it make any different?

Hi Dat Tran (Community Member)

Then you choose a TSV for MP157F-DK2 (not MP157C-DK2).

CubeProgrammer should work fine on both Win10 and Linux.

SDK should match your DV package you've downloaded (DV3.1 or DV4.01), but that's irrelevant here.

Hi @OlivierK​ 

Hi, the screenshot I capture from wiki that why it is MP157C.

I ran on my PC it was MP157F-DK2 already. I just installed everything from last week. Should are they up to date?

Note here is, all messages are returned sucesful, no error as you see on my first post. Just value at id 79th is not updated. I selected 79 because I see all lock value is zero, that make me think is it OK to read or write.

Is 0x12345678 has any special bit that prevent to update the word id 79th ?

[OlivierK]

Sorry, no I don't see anything wrong. I will double check

I tried the command line as your suggest, instead of GUI application, then I got this error, hopefully you will see something wrong in my side.

Nothing wrong on my side on windows 10

Hi @OlivierK

I got it working. From your answer, I found the problems on my side.

The latest STM32CubePro I installed last week is v2.11.0 and located on "C:\Program Files"

The earlier version 2.5 located on "C:\Program Files (86)".

Default system point me to 2.5. I uninstalled 2.5 and point to 2.11 and now working and output same as yours

Second is, seem "word=79" works, but "wordID=79" doesn't work, (says no error).

what is different word and wordID?

Anyway, got it working, thank you so much!
