Hotfix linker error #83

Closed maxgerhardt closed 2 years ago

maxgerhardt commented 2 years ago

Trashes a8 register by loading the target function, then does a call using that register.

As described in https://sourceware.org/binutils/docs-2.32/as/Xtensa-Call-Relaxation.html

No idea if this works, just for reference.

To properly fix this error, please recompile that rtc-board.c file with the -mlongcalls option!

See #82

Completely untested. Might crash and burn.

Noooo, people reported it still doesn't work after these corrections in #82!! Was this tested on hardware before merge?

maxgerhardt commented 2 years ago

Please recompile the library with -mlongcalls properly from source!
