As far as I understand, the partition table is flashed at 0x8000, and it's size is 0xC00. So the first partition should be able to start at offset 0x8C00, but in reality only 0x9000 is allowed. Why?
CSV Error: First partition offset 0x8100 overlaps end of partition table 0x9000
I have not changed the bootloader, nor the partition table offset.
