Subject: Failed to create MTD partitions
Date: Fri, 28 May 2021 21:00:52 +1000 [thread overview]
Message-ID: <CAA=hcWQk84==-Y2yq44M-EL_jwqb2Yg2QKJXY9fNycDfLUGOgA@mail.gmail.com> (raw)
Hello,
I am using MTD in kernel 4.19, I was able to run kernel boot to create
MTD partitions when I used NAND Winbond W29N02GV:
[ 7.961966] nand: device found, Manufacturer ID: 0xef, Chip ID: 0xda
[ 7.968545] nand: Winbond W29N02GV
[ 7.972267] nand: 256 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB siz
e: 64
[ 7.986814] Bad block table found at page 131008, version 0x01
[ 7.994254] Bad block table found at page 130944, version 0x01
[ 8.002152] 3 cmdlinepart partitions found on MTD device gpmi-nand
[ 8.008479] Creating 3 MTD partitions on "gpmi-nand":
....................
Since we could not get Winbond W29N02GV supply anymore, we changed
Samsung NAND, Both are 3.3V 2Gib devices with the same memory
organization (2k pages +
64b OOB / 128k blocks) so these two parts should be equivalent in
terms of internal organization, but it failed to create MTD partitions
in kernel boot:
[ 8.137591] nand: device found, Manufacturer ID: 0xec, Chip ID: 0xda
[ 8.144246] nand: Samsung NAND 256MiB 3,3V 8-bit
[ 8.148995] nand: 256 MiB, SLC, erase size: 128 KiB, page size:
2048, OOB size: 64
[ 8.158330] gpmi-nand 1806000.gpmi-nand: Error setting BCH geometry : -22
[ 8.166690] gpmi-nand: probe of 1806000.gpmi-nand failed with error -22
Since it is a new board, I suspect one of following problem might
cause that error:
- HW
- MTD does not support Samsung?
- Need kernel configure?
Appreciate your comments and advice.
Thank you very much.
