The issue is not the sd card - it is the onboard emmc. I dd’ed the miniroot image to a micro sd card. I the boot the bbb and run the installer. I set the install drive to the onboard emmc drive and when it tries to write to it, I get io errors. This used to work, as i had 5.6 on one of my bbb’s and 5.8 on another, both booting without micro sd cards in them.
I have received messages that suggest that this never worked, but I know I did this years ago following a post from tedu’s website. And i did flash the debian ‘flasher’ image to the micro sd card, booted it, and had it run through its reimaging process, and afterwards the bbb booted debian just fine, so the micro sd card and the emmc are both functional. > On Mar 20, 2021, at 14:52, Alan Corey <alan01...@gmail.com> wrote: > > man mount, then type /read-only to search, / to search for the same thing > again.
