Orange PI CM4 Questions

I am designing my base board with specific peripherals. Right now there is no booting from the EMMC.

What GPIOs do I need to use to work with the on-board EMMC?

thomasfrank

You must set up the GPIO pins on your baseboard correctly to allow booting from eMMC. Depending on the hardware design and CPU architecture you're using fnf, different GPIO pins may be needed.
