Seems you use the wrong toolchain.
Y17 ext is wrong path.

Also you need to make clean and then make first befor you type make wp76xx

Hi. Nice to meet again.
The cross-compilation chain I use is “poky-swi-ext-glibc-x86_64-meta-toolchain-swi-ext-armv7a-vfp-neon-toolchain-swi-ext-1.7.3.sh”

I executed bin/legs first, then executed make, but there is still an error.

make[2]: *** No rule to make target ‘user_docs’。 停止。

HI.

I changed the environment variable to the following and it succeeded! I tried this yesterday, but I didn’t succeed, so amazing. Thank you for your reminder
