Done, took a look into the video which is not very useful as is for Arduino in Arduino IDE. About the files needed to program the esp32 ulp, well is a tutorial for MAC and again for Arduino IDE… not useful for the reason of this purpose. I’m using Windows.
Also, took a look into the issue in espressif32 and the last comment basically says it all:
I have never used platformIO so I’m really not sure whats going on for you. The .s files are unique to how I differentiate between the ulp and xtensa assembly files for Arduino. Xtensa assembly is not the same as ulp assembly so I you need the binutils compiler files but again I have no idea how platformIO compiles it’s files so you will have to drill down on that first, maybe they have a verbose mode you can glean on how they compile and build your programs and go from there.
If you have a working example using PlatformIO using ESPIDF framework, then that will be useful.
