- 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

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
