Re: [flashrom] New SPI NOR Flash product Support

[Victor Lim]

Thanks, David,

For Gigadevice part numbers, we do keep ID, read, erase, write opcodes, sector protection, and architecture the same.

I am wondering if Flashrom program needs to call out the new part numbers so that users know which part number to choose from.

Regards,

Victor

Hello Victor,

Chips with same ID and read, erase, and write opcodes are supported. For ChromeOS platforms it is also important that new revision chips have identical block protection capabilities as the older parts (I've had difficulties with other vendors regarding this...).

Hi, Hatim,

We have new revision chips that share the same ID as the previous revision,
will they be considered supported because they share the same basic Erase
and program command.

New part # GD25LQ64C: manufacturer ID: 0x6017
Currently supported part # GD25LQ64: manufacturer ID: 0x6017

New part # GD25LQ128C: manufacturer ID: 0x6018
Currently supported part # GD25LQ128: manufacturer ID: 0x6018

Do you need new samples for verification?
We do keep the same ID for new revision release, so the SW should work for
new revision parts.

Regards,

Victor

Hello Victor,

I am doing fine, thanks :) The following chips have been tested successfully
- GD25D05B/10B, GD25LQ10B/20B/40B/80B, GD25Q21B/41B and GD25VQ41B (reported
by David Hendrix). Test logs for the first 8 of these chips can be found
here - https://www.flashrom.org/pipermail/flashrom/2016-March/014537.html.
The patches for all these chips and additionally GD25Q80C/16C have been sent
and are waiting for further review. I have ordered some IC clips, so I will
test the remaining chips as soon as those arrive. Unfortunately, one of the
chips you explicitly requested support for, GD25Q128C was not included in
the samples so was not tested. But support for it has already been added ;)
Apologies for the late reply. :)

New SPI NOR Flash product Support

[David Hendricks]

Hi Victor,
> From Flashrom's software perspective all chips with the same ID are

indistinguishable.

Part number often includes characteristics such as package and thermal
tolerance which do not affect software compatibility.
