Flash UID zeros after `--force-offline` #102

Open mossmann opened 2 weeks ago

mossmann commented 2 weeks ago

After running apollo info --force-offline the Flash UID shows up only as zeros in apollo info. Flash UID is displayed correctly again after apollo flash-info, various other 'apollo' commands, or a full device reset.
