Hi everyone,

Can someone guide me? I am not sure what I am missing here.

I am trying to debug the code but I assume that the SUNXI NAND driver is supposed to be working and that something is missing from my changes and additions to the dts/dtsi for A20 SOM.

Thanks in advance

Hi there Fawad,

I've hit this problem before and it's usually been because the pins are being used by another peripheral already

Could you post the kernel log? It might have some notes on this.

John.

Hi John, Thanks for your help. I found the reason for my issue. I defined the pinctrl information under the "soc" next to "nfc" entry in sunxi-a20.dtsi which was messing it up. I moved them inside the "pio" dtsi block and NAND is detected now. Though almost all blocks are reported as bad-blocks. I am thinking that it's happening as I don't have partition information defined in DTS. Do you think that this is the reason for bad-blocks reporting? Regards, Fawad Lateef
