oneo Posted March 1, 2021 Posted March 1, 2021 Hey there, so I was curious is there an easier way to make microSD take precedence in the boot order then having to futz with jumpers? Wanting to try out a new distro on microSD before deciding to make the switch and flash it to eMMC. If I do futz with jumpers I'll still be able to mount and write to the eMMC correct? 1
aprayoga Posted March 2, 2021 Posted March 2, 2021 The bootloader (u-boot) is configured to try loading OS from SD card first, then if it failed, it will try internal eMMC.

Expand You need to remove the jumper just before Linux initialized, otherwise the eMMC would not be detected. More info on our wiki.

I'll need to check via my serial cable because it skipped right to eMMC.
