Spansion S25HS512T NOR 闪存无法在 linux 或 u-boot 上工作

Question

我有一块带有 Spansion Flash 25HS512TFANHI010 的定制板 (NXP iMX6UL)，但我似乎无法正常工作。

我的dtsi有以下

...
pinctrl_qspi: qspigrp {
                fsl,pins = <
                        MX6UL_PAD_NAND_WP_B__QSPI_A_SCLK        0x70a1
                        MX6UL_PAD_NAND_READY_B__QSPI_A_DATA00   0x70a1
                        MX6UL_PAD_NAND_CE0_B__QSPI_A_DATA01     0x70a1
                        MX6UL_PAD_NAND_CE1_B__QSPI_A_DATA02     0x70a1
                        MX6UL_PAD_NAND_CLE__QSPI_A_DATA03       0x70a1
                        MX6UL_PAD_NAND_DQS__QSPI_A_SS0_B        0x70a1
                >;
        };
...
&qspi {
        pinctrl-names = "default";
        pinctrl-0 = <&pinctrl_qspi>;
        status = "okay";
        //cs-gpios = <&gpio4 16 0>;

        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>;
                spi-cpha;
                spi-cpol;
                m25p,fast-read;
                //wp-gpios = <&gpio4 14 0>;
                //hold-gpios = <&gpio4 15 0>;
                status = "okay";
         };
};

对于 u-boot，我的 defconfig 具有以下内容

CONFIG_DM=y
CONFIG_SPI=y
CONFIG_SPI_FLASH=y
CONFIG_SPI_FLASH_SPANSION=y
CONFIG_DM_SPI=y
CONFIG_DM_SPI_FLASH=y
CONFIG_FSL_QSPI=y
CONFIG_SF_DEFAULT_MODE=0

对于 linux 我的 defconfig 基本上（还有很多其他东西）

CONFIG_SPI_FSL_QUADSPI=y

所以 u-boot 和 Linux 似乎都不能正常工作

u-boot错误

我已经尝试了几乎所有可能的迭代，但我似乎可以解决问题。我有一种感觉，它与 dtsi 有关。任何帮助将不胜感激，我无能为力。

PS：尝试了赛普拉斯论坛，但他们的反应非常迟钝。他们有一个 2018.01 的 u-boot 补丁，因此与 2021.10

不兼容

Answer 1

已在 u-boot 2021.10-rc3 中添加对 S25HL/S25HS 系列的支持。

确保：

CONFIG_SPI_FLASH_SFDP_SUPPORT is set and
CONFIG_SPI_FLASH_BAR is not set

感谢英飞凌桑野先生的支持

PS: 未在 Linux 上测试。尚未在 Barebox 上工作（被检测但未写入）。
