Also having issues with eMMC boot, specifically the Android TV image. A few questions regarding shorting pins 23-25:
- Do I need to remove the RTC battery for this to take effect?
- Should I keep the pins shorted after powering up?
Shorting them while the board was off, and battery attached, did not help.
Here’s my boot log: https://gist.github.com/myxal/042ac6289d14f08e09168e9cc39a8331
EDIT: Never mind, found this post that explains what’ going on - Rock Pi 4A - emmc issues
- must be shorted while booting to take effect, is not a permanent fix
