[RFT] GL.iNet AR300M with Paragon NAND Chip

jeff · May 19, 2019, 7:32pm

I'm in the process of porting the AR750S to the ath79 target with SPI-NAND support now available on Linux 4.19. I'd like to continue with the AR300M, but don't have a device with NAND, in particular the Paragon NAND that I understand shipped with certain production units.

If you have an AR300M with the Paragon SPI NAND that you would be able to assist me in testing development of an upstream-supported driver, please also let me know. Testers with GigaDevice SPI NAND will also be helpful.

From looking at the GL.iNet source, I would expect to see dmesg on an OEM or image built from their sources to display a line containing

spi-nand: Paragon SPI NAND was found.

These are probably older-production units.

You should be comfortable with flashing images through the device's U-Boot. At least current-generation devices provide this capability over HTTP, without opening the case or a serial connection being required.

I should have a few of them, give me some time do dig them up and test.

Do you have a compiled image? I have an AR300M with GigaDevice NAND

jeff · May 20, 2019, 1:10pm

Thank you both!

Right now I'm wrapping up the GigaDevice GD5F1GQ4UFxxG patch with upstream Linux (or at least hoping I am ).

Knowing that Paragon-based devices are available for test was the first step. Next I have to write the "chip definition" code for the Paragon chip and configure a custom NOR-based build that has the NAND-testing tools in place. I'll probably do this after the AR750S NAND patches get further along.

Once the Paragon driver is confirmed running, that would go through the upstream Linux process, then the AR300M patch could be submitted here,

@luochongjun I typically don't do custom builds due to my beliefs around what is required to fulfill the licensing requirements of all the firmware involved (not just GPL). Once I get to the AR300M, as you've got GigaDevice flash, I would expect a relatively small patch set on master. I can make that available prior to OpenWrt review and (hopefully) acceptance of the full series.

I have an AR300M with NAND, however it's an older unit that, as far as I can tell, already operates fine with the current state of the 4.19 kernel tree (and worked fine 1-2 months ago).

The only things I know were missing were sysupgrade support. I should be able to take your AR750S work and backport that to AR300M when I get the time (next week hopefully?)

I'll take a closer look at the NAND chip identification next week.

hello,jeff

I have two AR300m, one using Paragon and the other using GigaDevice.

Hello. Have you seen this https://github.com/openwrt/openwrt/pull/1428 patch? I have this device, with this patch my device running on 4.14 kernel with NAND flash perfectly.

Yes, thanks. Note that it was rejected in favor of the upstream SPI-NAND framework that would become available in Linux 4.19. That framework is the basis of the work I’m doing.

Builds now available -- please PM me for access if you have a Paragon-based unit and are still interested.

I broke down and bought a GL-AR300M so was able to do functional testing on a GigaDevice-based device. While I think I've got a couple testers with Paragon NAND lined up, I'd definitely appreciate a check if you've got one of those units.

It takes a bunch of time to backup your unit, flash a couple of times through U-Boot (GUI OK), and then restore to your previous config -- this doesn't provide any "new" functionality and there isn't a package repo available for the build.

It will probably take a few weeks from when I have confirmation that the Paragon driver config works properly to get upstream Linux "nod" for the patch (well, at least not a "frown" from upstream) and then to submit to OpenWrt.
