事先烧写“分享一个 5寸的 800x480 的 f1c100s 固件, 感谢 @xm1994”帖子里的固件可以正常开机进入kernel。
下载linux代码：
git clone https://github.com/Lichee-Pi/linux.git
git checkout nano-5.2-flash

参考“U-Boot的编译和填坑”：https://whycan.cn/t_2179.html
编译出来zImage和dtb文件进行烧写替换，开机后log停在 “Starting kernel ...”，屏幕黑白条纹一直闪烁刷新。

log如下：

sf - SPI flash sub-system

Usage:
sf probe [[bus:]cs] [hz] [mode] - init flash device on given SPI bus
                                  and chip select
sf read addr offset|partition len       - read `len' bytes starting at
                                          `offset' or from start of mtd
                                          `partition'to memory at `addr'
sf write addr offset|partition len      - write `len' bytes from memory
                                          at `addr' to flash at `offset'
                                          or to start of mtd `partition'
sf erase offset|partition [+]len        - erase `len' bytes from `offset'
                                          or from start of mtd `partition'
                                         `+len' round up `len' to block size
sf update addr offset|partition len     - erase and write `len' bytes from memory
                                          at `addr' to flash at `offset'
                                          or to start of mtd `partition'
sf protect lock/unlock sector len       - protect/unprotect 'len' bytes starting
                                          at address 'sector'

device 0 offset 0x100000, size 0x10000
