which ulp are you talking about? what esp variant are you using. There are different ulp's for different variants. For example the esp32s3 has the classical ulp/fsm that is programmed in assambly but also has a second variant that can be compiled with a normal riscv toolchain. For the first variant you can find some examples in the riscv-ulp directory. If you want to see how you can interact with it from your normal application you can have a look inside the std-demo from ivmarkov here.

@Vollbrecht I'm sorry if I wasn't clear. I'm using esp32s3.I clone the std-demo of ivmarkov you mentioned, but unfortunately cargo check suggests me
no method named `load` found for struct `esp_idf_svc::hal::ulp::ULP` in the current scope
--> src/main.rs:1357:13
I'm not sure what's wrong with that
from esp-idf-hal.
you see that he is using a specifc sdkconfig file for the s2 here in the project and he mentiond that this example assume s2. Some of the methods are only availabe if ulp support is enabled via sdkconfigs. You can see the flags that are checked in the source code of ulp. So this needed to be set in the sdkconfigs with the appopriate names simmilar how its done in the demo's sdkconfig

I seem to have found the problem, my esp-idf version is 5.1.1 and the ulp compile condition requires a major version number of 4.

@Vollbrecht I solved this problem by referring to ivmarkov's demo and calling esp-idf-sys directly, thank you very much for your answer.
