Iam trying to build the ulp example given in esp-idf v4.0, its giving me the error:
fatal error: ulp_main.h: No such file or directory
image
Documentation explained that binutils-esp32ulp toolchain should be installed during ESP-IDF setup with CMake build system and Build system generate ${ULP_APP_NAME}.h and ${ULP_APP_NAME}.ld files, but in my case these files are not generated. Also when i build my code it open esp32ulp_mapgen.py file
