- GD5F1GM9UExxG (ID:c89101 3.3V)
- GD5F1GM9RExxG (ID:c88101 1.8V)
Both device feature:
- 1Gb density (1024 blocks)
- 2048-byte page size with 128-byte OOB
- 8-bit ECC requirement per 512 bytes
- Quad I/O Read support (opcode EBH)
- tPROG ≤ 300us typical page program time
Testing environment:
- Platform: Raspberry PI-5 (Linux raspberry 6.15.0-rc6-v8)
- Operations verified:
* Full device read/write/erase cycles on all blocks
* Nandspeed:
~ GD5F1GM9UE: 2.75MB/s read, 1.99MB/s write, 41.26MB/s erase
~ GD5F1GM9RE: 1.84MB/s read, 1.45MB/s write, 41.04MS/s erase
* Nandbiterrs: Both corredted 8-bit errors per 512 bytes
* Stresstest: Both 144k cycles 0 bad block growth

Applied to nand/next, thanks!
[1/1] mtd:spinand:gigadevice:Add support for GD5F1GM9 chips
(no commit info)
Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).
Kind regards,
