How do I open a uboot shell?

JayDev · ‎2023-10-04

I know this is probably a really stupid/noob question but I was trying to flash the STM32MP157D-DK1 board I have for the first time following the following guide:

https://wiki.st.com/stm32mpu/wiki/STM32MP15_Discovery_kits_-_Starter_Package

I ran into an issue where it started the flash and then couldn't reconnect. I did find this article that seems to describe exactly the issue I'm having:

https://community.st.com/t5/stm32-mpus/faq-stm32mp1-stm32cubeprogrammer-usb-reconnect-error-at-stm32mp1/ta-p/49263

It recommends:


In Uboot shell run a Dfu command  :

  STM32MP> env set dfu_alt_info "DDR ram 0xC0000000 0x20000000"

  STM32MP> dfu 0 ram 0

Unfortunately, I don't know how to run a uboot shell to try this. I know this is probably a really stupid problem . . . but I'm also hoping that means it has an easy solution as well. Any help you can give me would be greatly appreciated. Thanks!

Hi @JayDev ,

Did you tried another USB port on your PC, thru an USB hub ? With another PC, another USB cable ?

Maybe details your PC setup (W10 ? W11 ? USB-A or USB-C port ? ...)

I do have a ST-Link to the board and I'm watching the serial port @ 115200 and can see info coming in, I just don't know how to actually get to the u-boot to change the command. Maybe I'm getting closer but I'm not 100% sure. Thanks!

Hi @JayDev

to reach uboot prompt, simply press a key on the serial console at right time during boot sequence.

So, I've been trying to get this to work but still haven't seen the boot. I've tried plugging in the USB power and USB Micro/STLink and clicking the reset button but get no output. I've tried leaving STLink plugged in and resetting (both end up with LD6 blinking red on and off. I can plug in the other USB-C connector and the light goes solid. Still no output, even when resetting.

The only time I can get an actual output is when trying to program the device over USB in STM32Prog. This is the output screen I'm getting:

All signs appear to be pointing to the power supply, but that doesn't make sense to me as I'm currently using a 5V 3A supply (I'm using https://www.mouser.com/ProductDetail/TT-Electronics-IoT-Solutions/T7715DV?qs=vLWxofP3U2zWk%2FI5z4EHKA%3D%3D ). Is it possible the issue really is the power supply? Maybe it's dipping and browning out? Or is my current process for getting to uboot incorrect?

Thanks for your help and sorry for the delay! I should be faster to respond this week!

JayDev · ‎2023-10-09

Ok, since the last post, I went and found a phone charger (which likely has better USB protocols than a straight USB C 3A charger. It seemed to get past the previous issue so I was able to get into the boot mode and quickly type in


STM32MP> env set dfu_alt_info "DDR ram 0xC0000000 0x20000000"
STM32MP> dfu 0 ram 0

Now the issue I'm having is it seems to be timing out before it finishes programming the board. This is what I'm seeing:

Any ideas how to get around this issue? I'm not entirely sure how to change the timeout. I've essentially got the same result from the STM32 Programmer and from the CLI tool.

Well, the good news is I got a different outcome but I'm not entirely sure what that tells me, to be honest (though you likely do).

To be clear, my edited file currently looks like this (for confirmation):

Below is what my output was. Note it made it to 48% rather than the previous 12% and seems to have failed with chunk 2 instead of chunk 0.

If it helps, I also just tried to run:


STM32_Programmer_CLI -c port=usb1 -w flashlayout_st-image-weston/optee/FlashLayout_sdcard_stm32mp157a-dk1-optee.tsv

It appears this time it failed at 50% of chunk 0x12 and gave the following output:

@PatrickF

Any other ideas on where to proceed from here? I'm running out of ideas, unfortunately. Anything else I can try to get more information?

Hi @JayDev ,

Did you tried another USB port on your PC, thru an USB hub ? With another PC, another USB cable ?

Maybe details your PC setup (W10 ? W11 ? USB-A or USB-C port ? ...)
