jlink openocd error ?

[tabulous]

have progressed, apparently there is an issue with xtensa-esp32-elf-gdb.exe, and one needs to set an environment variable TERM to value xterm i.e.

set "TERM=xterm"



So i now have this, gdb connects to the

Hi

I am using Esp32 with Jlink and Jtag connection. I face the same error that you are getting every time i try to flash the esp using openocd in command prompt. Whats weird is for every 10 times i try to flash the code , randomly one time the code gets flashed successfully. I dont understand why its behaving like that.
Please let me know if you find any solution for this error.
