ESP32 debugging with Segger Jlink

[Karim1993]

ESP32 debugging with Segger JLink worked fine for me an Ubuntu 14.04 machine with the binaries provided. I just faced the issue with clock frequency which was later resolved.

Could you please first verify if you are able to debug from the command line, before using Eclipse? Please follow these instructions: https://docs.espressif.com/projects/esp ... index.html

you mean that "GDB debugging".

I built the openocd from source by following steps from https://docs.espressif.com/projects/esp ... linux.html

Then the command openocd -s . -f interface/jlink.cfg -f board/esp-wroom-32.cfg

Thanks,
Karim

Hi,
i followed the procedure which you have given in the link
Steps followed....

step 1-----> cd ~/esp
step 2-----> git clone --recursive https://github.com/espressif/openocd-esp32.git
step 3-----> sudo apt-get install make
sudo apt-get install libtool
sudo apt-get install pkg-config
sudo apt-get install autoconf
sudo apt-get install automake
sudo apt-get install texinfo
sudo apt-get install libusb-1.0
step 4-----> cd ~/esp/openocd-esp32
./bootstrap
./configure
make

step 5----->openocd -s . -f interface/jlink.cfg -f board/esp-wroom-32.cfg

this is what am getting
"Warn : Unexpected idcode after end of chain: 627 0x00000000
Error: double-check your JTAG setup (interface, speed, ...)
Error: Trying to use configured scan chain anyway...
Warn : AUTO auto0.tap - use "jtag newtap auto0 tap -irlen 2 -expected-id 0x00000000"
Error: auto0.tap: IR capture error; saw 0x0000 not 0x0001
Warn : Bypassing JTAG setup events due to errors
cpu0: Current bits set: none

Correct me if I am wrong and any suggestions on where I am going wrong is welcome.
let me know how to solve this.

thanks

hi Ningappa BS

Are you able to debug with Openocd and JTAG ?
