iMX6UL Custom board QSPI Problem

[bentales]

Hi,

I'm having trouble accessing QSPI (Macronix MX25L3206E) on linux user space, see details below. Any idea on how to solve this? All help will be appreciated.

dmesg output

[    0.989667] fsl-quadspi 21e0000.qspi: mx25l3205d (4096 Kbytes)
[    0.997023] fsl-quadspi 21e0000.qspi: Unsupported cmd 0x03

Device Tree Snippet

&qspi {

   pinctrl-names = "default";

   pinctrl-0 = <&pinctrl_qspi>;

   status = "okay";

   flash0: mx25l3205d@0 {

      #address-cells = <1>;

      #size-cells = <1>;

      compatible = "macronix,mx25l3205d";

      spi-max-frequency = <20000000>;

      reg = <0>;

   };

};

pinctrl_qspi: qspigrp {

   fsl,pins = <

};

Hi Ben

I have encountered the similar problem, how did you solve it later?

Maybe you could try a recent mainline kernel such as 4.14.14. If this still fails with this kernel, then please post it to the mtd-linux list.

You can run ./scripts/get_maintainer.pl -f drivers/mtd/spi-nor/fsl-quadspi.c to know the people and lists to send the email to.

Thanks for the quick reply, but I've already check this and the patch has been implemented on the current source code I'm using. Its been a week and still figuring this out. Hope to have more information about this error.
