Subject: S25HS512 not functional with u-boot 2021.10.rc3
Date: Wed, 15 Sep 2021 00:20:33 +0530	[thread overview]
Message-ID: <708882D3-8802-48F5-87BF-3A089ADB7391@gmail.com> (raw)

I have a custom board using imx6ul and Spansion S25HS512T Flash. On the current version of u-boot (2021.10.rc3) and I am guessing even previous ones the Spansion flash is not functioning

=> sf probe

Result is the same with different modes and frequencies, bus and CS are correct

My DTSI is 

&qspi {
        pinctrl-names = "default";
        pinctrl-0 = <&pinctrl_qspi>;
        status = "okay";

        flash0: s25hs512t@0 {
                #address-cells = <1>;
                #size-cells = <1>;
                compatible = "spansion,s25hs512t", "jedec,spi-nor";
                spi-max-frequency = <40000000>;
                spi-rx-bus-width = <4>;
                spi-tx-bus-width = <4>;
                reg = <0>;
                spi-mode = <0>;
                m25p,fast-read;
                status = "okay";
                /* some partition information*/
        };
};

Defconfig has

CONFIG_SPI=y
CONFIG_DM_SPI=y
CONFIG_FSL_QSPI=y
CONFIG_MTD=y
CONFIG_DM_MTD=y
CONFIG_DM_SPI_FLASH=y
CONFIG_SF_DEFAULT_MODE=0

I am unable to identify source of error returning -524 or why SPI Flash initialisation fails
