Hello all,
hope someone can help.
I’m trying to debug an ESP32 devkitC_V4 board with a Segger J-Link Plus debugger.
I’ve followed several tutorials and made some steps, but now I’m unable to proceed.
The code I’m uploading on the board is the famous “Hello World” example.
I’ve been able to lower the connection speed down to 500kHz.
Changed the USB driver with Zadig
When I press F5 and start the debug, this is the outcome:
Open On-Chip Debugger v0.10.0-esp32-20190708 (2019-07-08-11:04)
