Need help with JTAG on ESP-WROVER-KIT-VE
Posted: Tue Sep 28, 2021 8:51 am
Hi,
I try to use the JTAG debugger on my ESP-WROVER-KIT-VE in an Arduino and the esp-idf environment with Visual Studio Code and PlatformIO. I wrote a small program to test the debugger:
And my configuration file:
I set the jumper according to this (https://docs.espressif.com/projects/esp ... r-kit.html) guide to enable JTAG:
JP2:
RXD <-> TXD0
TXD <-> RXD0
MTMS <-> TMS
MTDO <-> TDO
MTDI <-> TDI
MTCK <-> TCK
The board is powered over USB.
I got the following output when PlatformIO starts OpenOCD:
What is wrong here? Why does the Debugger not start?
Please note: I have already asked in the PlatformIO forum, but they can´t help me.
