JTAG flashing on the ESP32-C6-DevKitC-1 V1.2
Posted: Tue Sep 24, 2024 7:21 am
Hi,
I am trying to use the JTAG port of my ESP32-C6-DevKitC-1 V1.2 for flashing.
I can connect to it just fine using:
But things go wrong when I do.
The output is:
Some things I have found out:
- Different cables produce the same result.
- flashing with UART/esptool via works
Any ideas why this is isn't working as documented in https://docs.espressif.com/projects/esp ... -debugging?
Thanks
Moritz
