Hi,
I am working with Visual Micro. Actually the hardware debugging fails with a ESP32 Dev-kit and a ESP32-PROG. The upload works via the ESP32-PROG device.
Do you have any ideas for this problem.

Thanks in advance, Andreas

thanks for your help 

It is a ESP32-WROOM device

greetings, Andreas

..thanks for your effort 

Andreas

thanks, I have downgraded to ESP32 core 2.0.0.
Now it seems that the debugger is working.

I have one more question:
In my example code I have set a breakpoint at bb=45, but it seems, that the debugger is not stopping (the red breakpoint circle has no yellow fringe)

example code:
/*
Name:            vMicro_debug_test.ino
Created:      07.03.2022 19:11:50
Author:      andre
*/

// the setup function runs once when you press reset or power the board
void setup() {
     int bb = 0;
     bb = 45;
}

// the loop function runs over and over again until power down or reset
void loop() {
     int zz = 0;
}

..thanks for your answer, but the debugger is still not stopping on the breakpoint.

Do you have another idea?

Greetings Andreas

I have found from much trial and error that if I run and start debugging with the esp32 only connected to the esp-prog and the esp32 *disconnected* from the usb input that it will start most of the time and stop at any set breakpoint. After the esp32 starts downloading only then reconnect the esp32 to the usb input to get the serial up. Once it runs one time as described above, I can then permanently leave the usb connected to the to the esp32 module and do a faster upload through the serial port.

Also to note that I randomly see the usb driver for the debugger revert back to the windows default and loose contact with the debugger. I often have to reuse the zadig utility to restore the configuration. When debugging I keep the windows device manager running and check that there is only one com port listed for the debugger and that there is an additionally entry under usb devices for the debugger.

Happy debugging!

Andreas,

Try changing these two lines:

  int bb = 0;
     bb = 45;

To:  "volatile int bb = 0;  bb = bb + 1;"

Then put the breakpoint on bb = bb + 1;

Good luck.
