故障现象:
1. 编译Uboot后, 将MLO.byteswap 烧写至Flash, SPI启动后输出

sf erase 0 +0x400000
mw.b 0x81000000 0xFF 0x200000
loadb 0x81000000
sf write 0x81000000 0 ${filesize}
启动出现报错(已添加额外打印信息):

2. 编译Uboot后, 通过Uart 下载 u-boot-spl.bin u-boot.img 能够正常识别Flash

3. 问题追查
目前初步定为 drivers/mtd/spi/sf-uclass.c] spi_flash_probe函数出现无法识别
4. 疑问
请问如何配置可支持SPI0 / FLASH 启动Uboot, 十分感谢

[补充] 经过检查am33xx-l4.dtsi spi0, 未发现帖子所述情况

Taylor：
您好，
已经收到了您的案例，调查需要些时间，感谢您的耐心等待
,
youlin cao：
[补充] 经过 fdtdump [SDK]/board-support/u-boot-build/spl/u-boot-spl.dtb 没有SPI0节点, 但board-support/u-boot-build/dts/dt.dtb 生成则包含spi0节点
,
Daniel：
您好
这是使用早期 SDK 时 AM335x SPI 引导

youlin cao：
谢谢回复, Daniel ，根据这个帖子我有新的启发。
1. SDK 6我目前不打算使用, uboot代码实现和SDK 9差距较大, 在本次移植前已经评估过;
2. SDK7.3我打算研究下, 如果可以SPL -> UBoot.img启动成功, 那我会对比下和当前SDK9的差别;
3. 目前我正在做的是在SDK9基础上, 修改SPL阶段代码, 加入了starterware 中有关的SPI Flash 读取代码, 绕过DM 驱动, 目前初步读取到了FLASH ID;
,
youlin cao：
[反馈] 关于 2. 我有误解, 是借用SDK7.3的deconfig, 不是直接使用SDK7.3, 否则配置spi deconfig 启动依旧报错

[反馈] 经过调试 , SDK6.0.3在新增configs内容后(如原贴所示) 未能支持SPI probe命令
