Issues while programming board STM32MP157C-dk2 over STM32CubeProgrammer. See details below.

STM32MP157C-dk2

I am trying to update the Board using SUART3 (Pins PB10, PB12) over STM32CubeProgrammer. The connection to STM32CubeProgrammer is established successfully. Unfortently after downloading the fdbl-boot (tf-a-stm32mp157c-dk2-uart.stm32)

the failure appears while system tries to start from downloaded part.

See console:

 19:26:23 : Start operation done successfully at partition 0x01

 19:26:54 : Timeout error occured while waiting for acknowledgement.

------------------

Are there any limitation to the UART used by given bootloader? Or what are other reasons which might be related to the issue?

Hi @WSief.1​ ,

Could you please share the log from serial console and details of ecosystem used ( CubeProgrammer and OpenSTLinux version )

Thanks,

Olivier

STM32MP1 OpenSTLinux Starter Package: 4.1.0

STMCubeProgrammer: v2.12.0

Hi @WSief.1​ ,

The log file you sent is still the one from CubeProgrammer on host side.

The one I have asked for is the serial log from target, usually on UART4.

Anyway, in the one you sent I can read :

"10:26:06:639 : Error: File does not exist: H:\W.Siefried\von JSLT\Piedrafita\Starter-Package\WMS\STM32MP157C-DK2/arm-trusted-firmware/tf-a-stm32mp157c-dk2-usb.stm32

10:26:06:713 : Error: TSV flashing service failed"

That's look to point to an obvious issue in your tsv file or binary file organization.

Typically path of such firmware in Starter Package is this:

\images\stm32mp1\arm-trusted-firmware

Why -usb flavor while I understand you want to program with UART3 ?

And, for my curiosity, why you program a DK2 with UART3 ?

On this board preferable path is USB, then UART4.

The described error is not related for issue (startup of programmer)

The configuration is loaded at 10:26:17:482 : Read TSV File....

I will check UART 4 and provide information.

In general: I am using UART3 as alternative to USB to check a developer board where USB currently not working. This eval board is used for verification purpose.
