I am in the same situation: PBP with Manjaro, SanDisk 64Gb 1A, IO error. I succeeded before in booting from SD, but not since installing Manjaro. Having another computer, I could flash an OS on the card (Manjaro again), but it does not boot either (sometimes I get an error about the filesystem being read-only). There are mutliple other threads talking about the same issue, btw: <https://forum.pine64.org/showthread.php?tid=10696&highlight=sd+card+not+working>.
