Couldn't find partition table, but command "rs" might still work !

[Z9044234820]

I erased the flash by edl es 0 $((0x102c0)) to reflash the partitions afterwards and when finished erasing, no edl commands work. I backed up partitions and partition table beforehand. Running any edl commands, even edl rs 0 1000 test.bin, results in Couldn't find partition table, but command "rs" might still work ! I restarted but same error. @bkerler

$ edl reset

Apparently the software won't let you do even an rs without a "partition table".
Does adding --memory=nand make a difference?
UBI/MTD/NAND doesn't have GPT partition tables, it has volume tables.

[bkerler]

Once the gpt is erased, it has to be flashed first before partitions can be written. I need to have a look why rs does fail, normally it shouldn't require a partition table.
