Flash Application using external JTAG

[Dakshk]

Hello,

Have anybody try to flash the binary files using any external jtag connector. Previously I have tried to debug using it but Now I want to flash application binaries into a fresh board.

I am using ESP32C3 board and Jlink EDU( Segger ) V-11.

I am getting the following output when I am following steps given here: https://docs.espressif.com/projects/esp ... up-openocd

Code: Select all

Thank you.

I have the exact same problem. Were you able to find a solution?

[nitro_orava]

I figured it out. Here's my situation for those of you reading in the future.

I am using a seeed studio esp32-c3 module with VS code IDF. which I assumed to have jtag because the IDE told me it was able to connect the JTAG.

The issue is that this board can not be programmed via jtag from the USB, you have to use the UART mode. I was able to program it after setting the flash method to UART, removing power from the board, pressing down the button labeled B, plugging power back in, and then using the IDE build and flash commands normally.
