我正在使用 u-boot (2021.04+fslc) 开发具有 Spansion s25hs512 的定制板，
该板正在从 NXP mfgtool 启动，并且运行正常。QSPI 也被正确检测到。读取没有问题，但写入失败而没有错误。
（我已启用日志级别 9 和调试驱动程序）
我的 dtsi 内容如下：
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 related Information here */
};
};
由于 s25hs512 id 不是本机的，因此在
rivers/mtd/spi/spi-nor-ids.c 中添加了以下内容：
{ INFO6("s25hs512t", 0x342b1a, 0x0f0390, 256 * 1024, 256, SPI_NOR_DUAL_READ | SPI_NOR_QUAD_READ | SPI_NOR_4B_OPCODES | USE_CLSR) },
我的配置
CONFIG_SPI=y
CONFIG_DM_SPI=y
CONFIG_FSL_QSPI=y
CONFIG_QSPI_BOOT=y
CONFIG_CMD_SPI=y
CONFIG_ENV_IS_IN_SPI_FLASH=y
CONFIG_DM_SPI_FLASH=y
CONFIG_SPI_FLASH_SPANSION=y
# CONFIG_SPI_FLASH_USE_4K_SECTORS is not set

在我的板上 sf 探针工作得很好

我努力了
- 保护一切
- sf 保护解锁 0x100000 0x40000
- 将 SPI_NOR_HAS_LOCK 添加到 spi-nor-ids.c
没有一个工作过
