ESP32-H2 Risc-V cpu extensions


Does the CPU implement the zicsr (control and status register access) extension? The instructions I've got are csrr, csrrw (from FreeRTOS).


Solution

  • I was expecting the Technical Reference Manual to mention zicsr; however, it does go into considerable detail about the CSR features of the processor, so I have considerable confidence.

    Also, come to think, the IDF package obtainable from Espressif includes FreeRTOS ...
