Having a problem debugging my code on my ESP32 C3 01M using vMicro and ESP Prog with Visual Studio 2019.
I updated the usb driver "Dual RS232-HS (Interface 0) using Zadig 2.7.765.

I would like your help to understand and solve the issue.

Here the full Micro Build output window:

Thanks for the report.

Can you confirm the full model of the ESP32C3 board you are using?

They are often setup for the onboard USB debug probe, which means external probes do not work without altering the fuse bits on the board (which cannot be undone):

Hi,
The full model name is ESP-C3 01M.

Thanks for the information, so this is just the ESP32 C3 01M without a full dev board built around it.

Can you confirm the connections are the same as on the page below:
https://www.visualmicro.com/page/ESP32C3-JTAG-Debugging.aspx

You will also need to add the local board.txt entries shown on that page as well to allow the debugging/upload to work.

Hey,

The JTAG wiring is correct.
I do burn the fuse DIS_USB_JTAG and now I get another error:

Does this link help?

Can you confirm you have added the local board.txt file (vMicro > Add Code > Add Local Board.txt), and the below entries:-

[code]debug.toolingsystem=gdbscript
# Most stable OpenOCD Version for newer ESP32 Boards
tools.openocd.debug.path={runtime.tools.openocd-esp32-0.10.1-2021.07.21.path}
tools.openocd.program.path={runtime.tools.openocd-esp32-0.10.1-2021.07.21.path}
tools.openocd.upload.path={runtime.tools.openocd-esp32-0.10.1-2021.07.21.path}
[/code]

Just to update on this (now we have the same exact chip setup, with the DIS_USB_JTAG fuse burned):

Upload via ESP-PROG:
There appear to be issues with this in all environments leading the ESP to constantly reboot, we will update when there is progress on this.  The only alternative we know at present for this is to use a USB-TTL Serial adapter and set the Upload tool to "No Programmer (Default)" (ensure GPIO9 is held LOW to upload via Serial)

Debugging:
We have successfully had this working with the additional board.txt entries from the documentation page, and then after upload via Serial, using Debug > Attach to Process.

Can you show an image of your wiring if you still have issues so we can compare to our setup?
