Can't flash my eMMC on STM32MP157

[LaurentC_FDI]

Hi all, we are trying to start our own board running a STM32MP157DAC1

We have so far been able to load the TF-A, OPTEE (only when configured in SYSRAM) and u-boot, our starting point is the openst-linux framework (5.0.2 - mickledore), on top of which we have added our layer to add our dts* and defconfig.

Right now, I am not able to program anything into eMMC (set to mmc1)

I got this message from STM32CubeProgrammer_CLI :

Could you please kindly give some hints to understand where I should look at ? Should you need the dts for analysis ?

As an additional note, we don't have a STLink connector, we use UART4 for the debug and USB OTG for the DFU. My boot jumpers are currently in Engineering mode.

When the system fails to write, the board is still present under "lsusb | grep ST" : 

Bus 003 Device 090: ID 0483:df11 STMicroelectronics STM Device in DFU Mode

Also, can anyone tell me why I have to run optee in sysram (it never works when optee configured to run from DDR)

Thanks in advance for you support 

Regards

Hi,

your problem is caused by the STM32CubeProgrammer reconnection after U-Boot start:

1/ on U-Boot start, the USB stack is started with DFU configuration to request the FlashLayout file (Phase 0x0)

2/ on Host side, the STM32Programmer try to access the requested phase after USB enumeration, by reading a specific alternate identify by Id 0xF1 

Sometime a reconnection issue occurs here because the USB enumeration is not completed when ST32CubeProgrammer try to access to USB resources so it doesn't find the alternates exposed by U-Boot (it is a libusb issue, we have to mean to wait the USB enumeration end).

In trace:

a) phase 0x3 is started => U-Boot start = USB disconnection and USB reconnection with new enumeration

Start operation done successfully at partition 0x03

b) as the PhaseId (located in the alternate identify with Id=0xF1) can't be read  the STM32CubeProgrammer reconnection failed

Error: an error occured while uploading data from the virtual partition 0xF1

=> normally this error can't occur except for this reconnection issue.

If you relaunch the same STM32CubeProgrammer command on host side, as U-Boot is still running and waiting the DFU requests, the programming sequence will be performed after USB connection (as now the USB enumeration is finished on the host).

To avoid this issue, you can try the latest STM32CubeProgrammer version, as some improvement of reconnection sequence have be done.

A other solution is to use the "-tm option  <timeout>".

See UM2237 = User manual, STM32CubeProgrammer software description

  Note: While programming the Flashlayout.tsv file, U-boot can spend a long time to start correctly,

  for this reason configure the timeout value by using the timeout command (-tm ).

NB: to test programmer support in U-Boot without reconnection, you can also start the programmer on the U-Boot console with the command:

Board$> stm32prog usb 0

then you can start STM32CubeProgrammer command on host with the same FlashLayout file.
