Hi,
I’m experiencing the same issue here. I have a Radxa CM3 IO Board and a Radxa Rock3 CM3 module with eMMC and I’m trying to boot from SD Card following the instructions Rock3/install/microSD - Radxa Wiki but there is no response. Even the Power LED’s on the Radxa CM3 IO Board are not powering up.
I’m only able to boot from eMMC without issues.
What do I’m doing wrong?
Many thanks,
Regards,
