iMX6UL Custom board QSPI Problem

bentales — Thu, 18 Jan 2018 08:01:45 GMT

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

Hi Igor,

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.

Best regards,

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.
