ESP32 Forum

I am trying to set up a debug environment for the ESP32-WROOM-32 adafruit devboard with a Segger J-Link on Linux. I have followed the steps using the following links:
1. https://esp-idf.readthedocs.io/en/v2.0/openocd.html
2. JTAG and ESP32 connection: https://gojimmypi.blogspot.com/2017/03/ ... esp32.html

I have doubled checked the connections. I am powering the board via USB.

I get the following error on the terminal.
Please help. Thanks.

Hi rohit,

This looks like it may be more of an issue on the Linux system than in openocd or ESP-IDF. If you look at the kernel log with a command line "dmesg", do you see any message from connecting the J-Link? Do you see the J-Link in the output of the command "lsusb"?
