the partition starting at 0x4400 is refused with overlap error: $> gpt write mmc 0 "name=test,start=0x4400,size=0" Writing GPT: Partition overlap error!
even if the 0x4400 is the first available offset for LBA35 with default value:
- MBR=LBA1
- GPT header=LBA2
- PTE= 32 LBAs (128 entry), 3 to 34
And the command to have one partition for all the disk failed also : $> gpt write mmc 0 "name=test,size=0"
After the patch :
$> gpt write mmc 0 "name=test,size=0" Writing GPT: success! $> part list mmc 0
Partition Map for MMC device 0 -- Partition Type: EFI
Part Start LBA End LBA Name Attributes Type GUID Partition GUID 1 0x00000022 0x01ce9fde "test" attrs: 0x0000000000000000 type: ebd0a0a2-b9e5-4433-87c0-68b6b72699c7 type: data guid: b4b84b8a-04e3-4000-0036-aff5c9c495b1
And 0x22 = 34 LBA => offset = 0x4400 is accepted as expected
