FS#1782 - unable to boot ath79 GL-AR300M NAND #8059
Comments

mkresin: The following from your bootlog looks related:
Please try to set num-cs in qca9533_glinet_ar300m_nand.dts to 2. |
|
mennozon: Changing num-cs to 2 did not seem to have an effect, boot log still shows cs1 >= max 1. That gave me the idea to swap around flash0 with flash1 to try and see if it'll detect the NAND device but did not work, it still couldn't register the device, also did not detect the NOR device, see attached boot log. |
|
robimarko: Well, I dont know how was this merged since NAND does not work. You can try something like this: num-cs = <2>; Then simply increment the GPIO number until NAND gets detected(Most likely GPIO1 or GPIO2) |
|
mennozon: I've tried GPIO 0 to 40 but no luck so far. I've looked into ar71xx sources to figure out what GPIO was used there but also no luck. GL-Net's docs[1] mention a few GPIO's up til 17 so I figured I try up to 40 for now but I could not find out how many GPIO's this device has, any idea how many I should try? I do notice a gpio enable function[2] in the ar71xx sources just before setting up spi, perhaps this could have something to do with it? [1] https://docs.gl-inet.com/en/2/hardware/ar300m/ |
|
mennozon: With software driven GPIO's and a patch applied I'm able to detect the NAND device, thanks to the information in the ar300m ath79 pull request[1] on how to do this. It does not boot yet but I think this is because of wrong bootargs. What I forgot is that the NAND device id's are not yet in the kernel, I've applied the needed changes from hanetzer's originals pull request[2] and together with software driven gpio's (cs-gpios = <0>, <0>, <0>;) things are looking better now, too bad I completely forgot about all this. The attached patch is based on hanetzer's work, I hope to have some time this week to figure out the last pieces to get this booting. |
|
mennozon: I think this bug report should be closed, I was confused with the fact that ar71xx had working nand support for GL-AR300M but it was probably never merged, I was using a local branch that included the patches. With the information in mentioned pull requests I was able to get it working eventually. I created a pull request[1] that hopefully can be merged. Thanks [1] #1428 |

adrianschmutzler: NAND support for ath79 and kernel 4.14 has never worked and has been disabled in 19.07 for that reason: With kernel 4.19 and current master, GL-AR300M and others have been updated to work properly in the meantime. |
mennozon:
Supply the following if possible:
ar71xx NAND works fine on GL-AR300M but ath79 target does not want to boot, it seems NAND is not detected even though kernel support seems to be there.
