Can't boot when SD card inserted
09-04-2022, 03:40 PM
TL;DR I'm experiencing this issue but with the Pinebook Pro and the solution outlined there isn't helping me: https://forum.pine64.org/showthread.php?tid=6819
So I've recently upgraded the eMMC in my Pinebook Pro to 128 GB, and I wanted to use an SD card as the home partition. I've partitioned it as the following:
I've formatted /dev/mmcblk1p1 as f2fs, and added a line for it in /etc/fstab, but if I reboot the Pinebook with the SD inserted, I get a black screen, and the power LED stays red. If I boot with it removed, it boots from eMMC just fine, and if I re-insert it quickly enough it's mounted as desired.
This is a minor inconvenience, though, so I'd like to get to the bottom of why it's happening, or at least figure out how I might be able to fix it.
I'd previously flashed (using dd) the latest Armbian image to this particular SD card that I'm using, so prior to making the partition table, I zeroed out the first MiB to attempt to get rid of any sort of U-Boot data.
So, what do I need to do to have my Pinebook Pro boot to eMMC in the case that the inserted SD card isn't meant to be bootable? (I'd still like to be able to "rescue" my system by removing the one containing the home partition and inserting a bootable SD in its place.)
