STM32MP157C-DK2 not getting populated.

[Puranjay Mohan]

I am trying to flash a 32gb sd card with stlinux for STM32MP157C-DK2 using the guide at https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157C-DK2/Let%27s_start/Populate_the_target_and_boot_the_image

The SD card that came with the kit boot perfectly, I just want to flash another sd card.

I am using Ubuntu 16.04 LTS on my laptop

details about my STM32MP157C-DK2

Serial number(below pcb) : DK32MP157C2$AU1

These are the commands I ran and the output I got on console :

$ STM32_Programmer_CLI -c port=usb1 -w flashlayout_st-image-weston/FlashLayout_sdcard_stm32mp157c-dk2-trusted.tsv

You use a supply which is not USB Type-C compliant !

Error is issued because uBoot does not detect the right CC lines levels as required by the USB standard. So boot process stop (This is a SW choice for our DK2 started package, you are free to modify/rebuilt uBoot to ignore this).

Please have a look to this post which list some tested supplies: https://community.st.com/s/question/0D50X0000Bftr1ySQA/power-supply-for-stm32mp157cdk2

Thanks for the info,

Can you provide me with some resources related to development using the DK2 Kit, I want build a user interface for a project.

I am familiar with MCUs but when using an MPU such as in the DK2, how would one make a solution where when the device is booted up, a user interface opens automatically for some HMI and the user can interact using the screen, I also want it to be able to connect to wifi. How can one build something like this using the DK2.

Please help me.

Thanks in advance.

I was thinking about writing a GTK3 application and sending it to the DK2, but how would connect to wifi and send API requests to server.

Yes it is a good idea to use GTK, you will find many help from the community and some basic samples applications developed by ST (GTK + Python) on the starter packages.
