Starting to ‘explore’ the system, and it looks very different from the typical Linux system I have been used to since 1997..   The base directory structure is different, with many ‘additions’..

This is probably standard for Android, but not what I am accustomed to!

I decided to format a (micro) SD card, and insert it, as this may form the basis of my efforts to put a standard distro on the device..   This appeared to be recognised, but then generated a ‘tombstone’..

~ # mmc0: new high speed SD card at address 1234
mmcblk0: mmc0:1234 SA02G 1.83 GiB
 mmcblk0: p1 p2

When I checked the ‘Storage settings’ screen on the Anrdoid display, it only showed the 500MB of the first partition (p1) on the card, ignoring the second partition..     From the output above, the second partition (p2)  had been found by the underlying OS..   I tried unload / loading, but there was no difference…     Again, this might be standard Android behaviour!

This would suggest that the kernel still has some bugs to be ironed out…     Once again, this is typical for an ‘early adopter’ system with limited production run..

More to follow!
