request a script of flash cod to eMMC from SD on stm32mp157c-ev1

[zqizh.1]

Hi,

My evaluation kit is stm32mp157c-ev1, I can flash code to eMMC or SD via STM32CubeProgrammer successfully, and it can work expectedly.

We need to running program on eMMC without SD card. Flash the eMMC code via STM32CubeProgrammer is very slow and is not suitable for mass production.

Please support a script that flash eMMC code "stm32mp1-openstlinux-5.10-dunfell-mp1-21-03-31" via SD card.

Thanks,

QiZhang

Hi @zqizh.1​ ,

Please have a look to post

https://community.st.com/s/question/0D50X0000BiBhHQSQ0/stm32mp153a-failed-to-boot-from-emmc

It contain a guide to load eMMC from SDcard with Uboot.

Does it suit your need ?

Hi Olivier,

Your solution is not I want.

Below script is I got from internet to write the image to eMMC card from SD card.

But I don't know how to create eMMC image "atk_emmc-stm32mp157d-atk-qt.raw".

Your distribution package include a script "create_sdcard_from_flashlayout.sh" which can generate a SD card image, Please support a similar script to generate a eMMC image for me.

Thanks,

QiZhang
