not sure what should be our action here? You are free to use the ULP if that will help you cause.

I cant use ulp because is not enabled by default , i've tryied to compile arduino core myself but i failed , it compiled but then when flashed resulting in a core panic store prohibited :
command i've used
`git clone -b release/v4.4 --recursive https://github.com/espressif/esp-idf.git
cd esp-idf
./install.sh esp32s3
. ./export.sh
cd
git clone -b release/v4.4 https://github.com/espressif/esp32-arduino-lib-builder
cd esp32-arduino-lib-builder/
sudo ./build.sh -t esp32s3 -b menuconfig

./build.sh -t esp32s3 -A idf-release/v4.4 -I release/v4.4`

ulp_fsm is not included for -S2 and -S3 in 3.0.0. Does that issue go in lib-builder @me-no-dev ?

[me-no-dev]

Does that issue go in lib-builder?

Probably yes, if all that is needed has to be enabled there. Can fsm_ulp and riscv_ulp work together? if not, then the RV is preferred.

assigning to 3.0.5 milestone, lets resolve this ticket.
