【求助】f1c600上烧录f1c100suboot和kernel报错unrecognized/unsupported processor

xichuangxue · 2026-09-25 12:17:30

各位大佬，咸鱼买了一片f1c600的板子，原本是nor Flash到手后换成128M spi Nand了。
编译了榴莲派的boot和kernel, 在手头的f1c100s上正常运行。但烧录到f1c600上后，启动kernel报错如下。万能的坛友，有知道原因和解决方案的吗？

原本以为是uboot和kernel macheine ID不一致导致。但相同IMG 烧录到f1c100s上是可以正常启动的，且打印的mache ID也是41069265。故排除了这个原因。

uboot中bdinfo如下：

Linux 内核识别 CPU 时失败：

f1c600 有几个 otp 寄存器不同，你跟踪一下这个log

感谢晕哥指导。
debug 下来发现不是 otp 寄存器不同导致。说明下debug过程。
让AI找关键打印，AI review code发现这里不存在问题。建议排除zImage完整性。于是按下面验证。

---------------------in pc 
crc32 zImage
57b3bf67
---------------------in f1c600
=> mtd read spi-nand0 0x80008000 0x120000 0x560000
=> crc32 0x80008000 0x4e3688 
crc32 for 80008000 ... 804eb687 ==> 0f74d416
---------------------in f1c100s

=> crc32 0x80008000 0x4e3688 
crc32 for 80008000 ... 804eb687 ==> 57b3bf67

然后通过串口加载zImage，发现可以正常启动。

现在确认了是板子上的 zImage有问题。
烧录前有整片擦除，试过烧录到其他地址，发现还是一样。
目前怀疑是板子上的spi nand有啥问题(但没有证据)。

xichuangxue · 2026-09-28 21:39:48

破案了，原因是 f1c600 使用的uboot和kernel 原本不支持 MX35LF1G24AD这颗flash, 虽然改代码中ID，可以起来，但读写还有问题。
替换成W25N01GV后，可以正常烧写和启动。
另外请教下，看论坛中的帖子中有的说 f1c600 是64MB in chip DDR，有的是说是32M，到底是多大？

原来如此，又学到新知识了，感谢分享。
