Manual for flashing the eMMC with OpenSTLinux?

[DMårt]

Hi!

I have made a simple computer with STM32MP151AAC3 processor.

I have modify so I can boot either from UART4 or eMMC. My question is:

When I want to flash OpenSTLinux onto the eMMC, can that be done via ST-Link and STM32CubeIDE? Just like regular STM32 programming via STM32CubeIDE?

If yes: Is there any manual how to flash the eMMC with OpenSTLinux via UART4 so my processor can boot from eMMC?

I have attached the schematic. Just tell me if I'm missing something. I have included:

• LSE
• HSE
• Boot (Only BOOT1 can be set HIGH. BOOT0 and BOOT2 is default pull-down)
• RESET
• External ST-Link debug via 1.27 x 2 connector (I assuming that a Nucleo STM32 can be used as ST-Link programmer)
• HDMI
• DDR
• eMMC
• USBH 
• USB OTG
• Gigabit Ethernet
• PMIC with 3.5 mm DC plug connector

Hi @PatrickF 

Can you explain why my PWR_ON won't have any actions in my schematic?

This is from my board.

This is from the dev-kit. I assume that the zero-ohm resistor should be removed and replaced with a track only. But the capacitors should not be replaced with a track.
