Hello Ram, First off, thank you very much for this patch and your work on the ipq40xx platform. I have been doing more testing, and it seems that some of the pins in pinctl are not defined to the correct function. This is what I am currently seeing on the board: [ 1.278649] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio57" for function "qpic_pad" [ 1.279841] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio58" for function "qpic_pad" [ 1.288214] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio59" for function "qpic_pad" [ 1.296508] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio60" for function "qpic_pad" [ 1.304905] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio64" for function "qpic_pad" [ 1.313190] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio65" for function "qpic_pad" [ 1.321522] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio66" for function "qpic_pad" [ 1.329856] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio67" for function "qpic_pad" [ 1.338190] ipq4019-pinctrl 1000000.pinctrl: invalid group "gpio68" for function "qpic_pad" With that said, NAND still inits and works. I was also able to clear up the errors by fixing the groups for each GPIO in my DTS with the help of Christian. Example of this is at https://pastebin.com/rQDY3z9c. Is this something specific with my board, or some other variation with your patch? I am new to this arch so please excuse me if any of this is noobish. :) Regards, Chris Blake _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
