Open OCD fails on MAC OS 11.5.2 (OCD-407) · Issue #179 · espressif/openocd-esp32 · GitHub

Environment Problem Description

Steps to reproduce the behavior:
Hi ,

I am trying to setup the debugger on ESP WROVER E Kit and I have ESP Prog . I realized that this version of mac does not support kext but dext. I have the beta version downloaded from site and ran it in my application folder .

I have the port recognized as

cu.usbserial-14220
cu.usbserial-1423100
cu.usbserial-1423101

tty.usbserial-14220
tty.usbserial-1423100
tty.usbserial-1423101

When I run open OCD I still get the below error . I am trying this on Command line. Am I missing something ? Is there any documentation I can refer to ?
