My
sdkconfig.defaults
file is always ignored. And it takes so much time before I figure out why. I never haveCARGO_TARGET_DIR
unset, because I don't want to fill up my source code folders with build artifacts. Thisembuild
caveat is poorly documented. It would be great if theesp-idf-sys
documentation would mention it.I would add a link to a reference on why this is needed if I had one. But I can't remember where I learned about this workaround. I learned about it a long time ago but then I forget about it every time I pick up esp programming.
