Which esp-idf version did you use? You can get the Version with: $ git describe

In the begining with esp-idf v4.2
And with esp-idf 3.3 realease
can't finish "build"

I tried with the firmeware for the camera F but it does not work.
M5camera V1.0.0

I try with ESP-IDF (Windows 10)
5stack-cam-psram-master\m5stack-cam-psram-master\wifi\wifi_sta\firmware\Camera F
I am sure there is not much missing
