AT91SAM9X25 AT91SAM9G25 OpenWrt compilation and debugging pitfalls

Compiled LEDE-17.01.7

18.06.8

19.07.3

These release versions

I found that except for the LEDE branch, the others could not run. When it came to the UBI file system, an ECC return -74 error occurred.

No reason found

No problems with using LEDE branch

The openwrt system LEDE branch can be started normally. It can run on AT91SAM9G25.

WEB can also update NAND's kernel+dtb+rootfs (squashfs+ubi)

The effect is similar to that of Nuvoton NUC980 running openwrt, but AT91SAM9G25 is faster, 400MHZ
