Compute Module • CM4 USB erased and re-install clean OS remembers everything

$
0
0
CM4 with 8gb RAM running off a 128gb USB stick.
Getting problems, so time for clean install of only what I need.

Put USB into MAC and installed clean OS
Returned to CM4 / booted and all the old s/w is still there
Erased the USB in the MAC using the disk utility showing only 538meg available (?)
Installed new copy of the OS onto the erased USB
Booted the CM4 off it and the old s/w is still there.

Repeated for another USB and the same results.

Common sense tells me that this is not right - but WHAT am I doing wrong?
All help would be appreciated
Thanks
Steve
