@Ouss4 I think I have find the reason:
CPU1 have not generate swi interrupt anymore.
As esp32 only have two software interrupt bit:
`#define ESP32_CPUINT_SOFTWARE0 7`
`#define ESP32_CPUINT_SOFTWARE1 29`
I select ESP32_CPUINT_SOFTWARE1 for CPU0 swi interrupt .
As the ESP32_CPUINT_SOFTWARE1 have interrupt level-3.
But ESP32_CPUINT_SOFTWARE0 is interrupt level-1.
I'd like to know, CPU1 must use another sw interrupt pin to generate
interrupt in ESP32?
