大家好！
我在定制 FS HS-QSPI 板上从 QSPI 引导时遇到问题。
- 我们能够使用 DFU 模式成功刷写 QSPI (tiboot3.bin、tispl.bin、u-boot.img)。
- SF 探针工作正常、并且在完全 U-Boot 中正确检测到闪存 (Winbond W25Q512JVFIM)。
- 但是、从 QSPI 引导时、它在 A53 SPL (tispl.bin) 中失败、并显示错误：SPI 探测失败。
详细日志：

我们在 drivers/MTD/SPI/SPI-NOR-IDs.c 中添加了以下补丁来支持此闪存：
｛info（“w25q512jvfim“、0xef7020、0、64 * 1,024,1024、
Sect_4K | SPI_NOR_DUAL_READ | SPI_NOR_Quad_read |
SPI_NOR_4B_opcode | SPI_NOR_HASS_LOCK | SPI_NOR_HASS_TB)｝、
因此、我们将检测 QSPI 并能够刷写。

我们已经尝试过的方法：
- 在 drivers/MTD/SPI/SPI-NOR-IDs.c 中添加了 Winbond 闪存 ID (0xef7020)
- 使用四通道模式 (SPI-TX/Rx-BUS-WIDTH =<4>)
- 已尝试 SPI-max-frequency =<25000000>和<10000000>
- CDN、读取延迟尝试 0、2、4
- 添加了 CDN、phy 模式
- 多次重建并重新刷新 tiboot3.bin + tispl.bin
我们使用的是 U-Boot 2024.07 + BuildRoot。
关于 A53 SPL 器件树或定制电路板 QSPI 引导配置中可能缺少哪些内容的建议？ 尤其是引脚多路复用、OSPI 控制器设置、或任何 FS 特定于 HS-OSPI 的要求？
提前感谢！
