Q1:my ESP32 module boot from ESP32 error?, how to fixed it?
ino@ino-VB:~/esp/esp32/esp-idf/examples/01_hello_world$ make flash

and Bootloader have a console read input function, Why this function not open to esp_idf SDK?

module auto recovered after a power cycle , I have no idea why it happen!

Q1: No idea. You don't really give us much to go on.
Q2: Because the console method is pretty specific to the Basic-interpreter; it also does some more things than just check the console. Also, the Basic-interpreter is unpacked to RAM before use; you can't just call its routines from ROM.

@ESP_Sprite,

I got Q1 issue again,
when attached JTAG & UART both, UART log work abnormal.

Check your esp32.cfg; you should configure the right flash voltage there. Also please keep OpenOCD running while JTAG is connected. The problem you may be running into is that GPIO12, which is also TDI, on bootup sets the flash voltage. OpenOCD should normally take care of setting that toi the right voltage level, if so configured, but it can only do that while it's running.
