do I need to wipe out the eMMC before flashing a new OS to it?
In fact, I didn't do it, and after booting from the eMMC lsblk reports, in addition to the expected mmcblk2p1 and mmcblk2p2, two additional entries: mmcblk2boot0 and mmcblk2boot1. I wonder if those are left over from the previous OS...
Many thanks in advance!!
I'd recommend at least formatting before flashing an install.
A zero wipe can take quite a bit of time.
Thanks a lot @bcnaz !
Just to be sure, - by formatting you mean creating a partition and a filesystem (a combination of parted and mkfs), right?
By wiping I meant dd if=/dev/zero etc. (without any partitioning, because the new image already is partitioned (and has a filesystem)?
I do have the time for the latter, just wanted to make sure there is no harm done using dd on the eMMC :-)
Many thanks!
