Micron NAND device connected to GPMI nand controller is not detected.

Pin mux settings seems correct.

Hi kiruthika

from log seems it even can not read NAND ID,

had you checked hardware with SDK (simple NAND ID read procedure) ?

i.MX 6Series Platform SDK : Bare-metal SDK for the i.MX 6

Best regards

Hi Kirthika,

Did you have to change anything in the device tree or driver to get the NAND to work?

Thanks,

Akshay

Hi Akshay,

I added the following lines to DTS file

1. &gpmi {

        pinctrl-names = "default";

        pinctrl-0 = <&pinctrl_gpmi_nand_1>;

        status = "okay";

};

2. Make sure that pins of pinctrl_gpmi_nand_1 is not muxed with any other devices.

With kernel configs enabled for GPMI NAND it works straight away.

Thanks,

Kirthika
