So, I'll answer this question by myself: The problem is the ulp_riscv_delay_cycles function: void static inline ulp_riscv_delay_cycles(uint32_t cycles) { uint32_t start = ULP_RISCV_GET_CCOUNT(); /* Off with an estimate of cycles in this function to improve accuracy */ uint32_t end = start + cycles -...

Hi, I made a very simple ULP (RISC-V) test program for an ESP32-S3 module (ESP32-S3-WROOM-1) on a lilygo T7-S3 board. I'm using the latest ESP-IDF 5.2.2. My test program is based on the "examples\system\ulp\ulp_riscv\gpio"-example, so take the configuration from there. The problem is that the functi...
