Hi,

I have a project that compiles fine under IDF V3.3.

When building under IDF V4.0 beta 1 I got the following error:
e/GitHub/esp-idf-v4.0-beta1/components/unity/include -IY:/VM/Share/GitHub/esp-idf-v4.0-beta1/components/ulp/cmake/-IY:/VM/Share/GitHub/esp-idf-v4.0-beta1/components/unity/unity/src -IY:/VM/Share/GitHub/esp-idf-v4.0-beta1/components/ulp/cmake/-IY:/VM/Share/GitHub/esp-idf-v4.0-beta1/components/wifi_provisioning/include -IY:/VM/Share/GitHub/esp-idf-v4.0-beta1/components/ulp/cmake/-IY:/VM/eclipse-workspace/tmp108logger/components/esp-si7021/include -o CMakeFiles/ulp_main.dir/sensor.ulp.S.obj -c sensor.ulp.S

Is there a way under IDF V4.0 to build ULP code using seperate assembler files?

Are you using latest ulp toolchain?

When using the cmake idf v4.0 the ulp toolchain is embedded.

If you have already set up ESP-IDF with CMake build system according to the Getting Started Guide, then the ULP toolchain is already installed.

Building using legacy GNU make build is older and works.

Any idea how to use multiple assembler files using CMake? That could also solve the problem.

message only exists in the old toolchain. It was removed here https://github.com/espressif/binutils-e ... 8bff1e18e1 Do you have an older version installed that may still be in PATH?

Hi,

Yes the esp32ulp toolchain was configured twice in PATH.

I builds now using CMake.

Thanks
