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 = <
      MX6UL_PAD_NAND_CLE__QSPI_A_DATA03 0x70a1
      MX6UL_PAD_NAND_CE1_B__QSPI_A_DATA02 0x70a1
      MX6UL_PAD_NAND_CE0_B__QSPI_A_DATA01 0x70a1
      MX6UL_PAD_NAND_READY_B__QSPI_A_DATA00 0x70a1
      MX6UL_PAD_NAND_WP_B__QSPI_A_SCLK 0x70a1
      MX6UL_PAD_NAND_DQS__QSPI_A_SS0_B 0x70a1
   >;
};

 

Thanks,

Ben
