Where to get the original SD-image of the STM32MP257-DK board?

[HMüll.4]

Hi,

I'm aware of the manual from https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Let%27s_start/Populate_the_target_and_boot_the_image but it does not solve my problem as it seems to be completely faulty:

• different to the description, not USB has to be choosen as connection but UART
• when downloading, there is never a completion-message but it always ends up with an timeout (no matter what image I try)
• at the end, it comes up with an error message "Partition 0xBB not found in TSV file"
• the resulting SD-card obviously has not changed at all after this cycle

So where can I get an image for the Sd-card that can be copied with a simple imager or the dd-command from Linux instead of following this non-working, complicated procedure?

Hi @HMüll.4 

Link you refer address STM32MP157DK2 while you seems to work with STM32MP257-DK

Is it a mistake? 

The equivalent procedure for STM32MP257-DK is here :

STM32MP257x-DK - stm32mpu

Getting started is the most simple and straight forward way to use the board. 

UART boot is limited to small software like BSP or DDR_FWUtils but can't load a full linux system

USB is supposed to work and so if you have trouble at that stage please share

Sorry, I used the wrong link because I was trying this stuff on one computer and were posting the question from an other one. So to clarify this:

I mean the 257-DK board and I was using the description from https://wiki.stmicroelectronics.cn/stm32mpu/wiki/Getting_started/STM32MP2_boards/STM32MP257x-DK/Let%27s_start/Populate_the_target_and_boot_the_image (so 257 too).

And this description is not working in the way as mentioned in my original posting...

Hi @HMüll.4 

Strange. Please check that you power the DK properly from a PC TypeC. (typeA don't deliver enough power) 

If this is ok and still have issue please describe it further with log and trace

HI @HMüll.4 ,

Populate complete Linux image using UART is not recommended/viable due to extremely long time (probably more than a day). UART flashload is only useful for image up to uboot, e.g. for early custom board bring-up debug when USB has Hw issues.

So, with STM32MP257F-DK, please try using USB or populate SD-Card on your Linux PC using https://wiki.st.com/stm32mpu/wiki/How_to_populate_the_SD_card_with_dd_command

@PatrickF Connecting it via USB does not work - neither form Linux nor from Windows the CubeProgrammer detect anything!

When connecting the board using Windows, I get two COM-ports COM3 and COM5 where one at least accepts a connection from the CubeProgrammer but then fails with the timeout mentioned in my first post.

The USB-connection itself _is_ a proper USB-C.

Hi,

On STM32MP257F-DK, while CN21 is using to power the board, debug using ST-Link and get console, did you at same time use the CN15 to connect to the PC for the DFU flashload ?

While board is powered, is the red LD7 stop flashing (either on or off) when you connect the CN15 USB to the PC (this mean correct USB PC detection) ?

Note: UART/USB boot need BOOT pins in correct position as listed in the wiki:

Regards.
