If I wanted to completely erase my old i.MX8MP, before upgrading to the new Rockchip, should I just boot off of an SD card image, delete the partitions on mmcblk2, and maybe create a new encrypted partition on it? Would that suffice? Would something else be a better idea?

Deleting the partitions will not delete the actual data. Somebody else might want to correct me on this but I don’t think that the eMMC in i.MX8M+ has wear leveling so it should be sufficient to just write zeroes onto the whole drive. The important bit is that you do not zero-out u-boot which lives on /dev/mmcblk2boot0 but filling /dev/mmcblk2 with zeroes will not touch that part.
Thanks, running on those two partitions now. I’m not worried that much about the data on there, but writing /dev/random over those two partitions should let me not worry about disposing of it or selling it later. (It is one where the external video died, so I doubt it’s worth anything at this point.
The external video died? Do you mean the micro-HDMI port broke off?
There was a thread here: Pocket Reform, HDMI output lores And minute responded in October that sometimes the ixm boards did this. I was chatting with them last night on IRC, and they said to put in a ticket on the site, which I did.
I just opened it up, the connector doesn’t seem physically broken. Seems like it’s still connected, but the video only shows 640x480, 800x600, and 1024x768, but no video comes out, in any case.
No, the port is still there, but when I plug in a monitoe, it only shows those three modes, but there is no video output. Same problem that I’ve been seeing for almost a year.
Very frustrating. Not sure what to do to resolve this.
Isn’t the monitor to be the problem? Can (did) you try another one? I never noticed any issue with an external monitor on the Pocket (both on the ixm and rcore boards).
Three different monitors, different cables. I’ve been going through this for months.
Should I put in a ticket for this issue?
Feel free to open a support ticket for this issue, it seem like this issue has been ongoing now for a long time.
Since you upgraded to the RCORE and you see the same thing, I am wondering if you are on an old version of the system controller firmware. What does the OLED say when you press hyper + enter and then s ?

Same date on both the main, and keyboard. Haven’t seen an update in the Gnome firmware updater in a while….
