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.
