Compiling openocd-esp32 on Raspberry Pi

Is there any news on this topic? I tried installing openocd-esp32 on a Pi Zero but compiling fails. Compiling the 'generic' openocd version actually succeeds however?

Hi,
I split your post off into a new topic because it relates to compiling rather than running openocd-esp32.
The extract of the build output you posted doesn't go quite far back enough to see the original error. If you copy some more of it then we may have some better clues.
It may come down to a build dependency missing. If you're on Raspbian, running "sudo apt-get build-dep openocd" (install build dependencies for Debian's openocd package) may help. Also it may help to re-run "./configure" and look for any warnings in the output.

I forgot to enable the putty log file...oops! I started over and here is the resulting log:
http://pastebin.com/dl/rUjWFruV It is not the same as the first time though. Now the problem seems to clearly visible.
This seems to be the offending line:
Code: Select all
rtos_freertos_stackings.c: In function 'rtos_freertos_esp108_stack_read_voluntary':
rtos_freertos_stackings.c:375:22: error: cast increases required alignment of target type [-Werror=cast-align]

I changed the '__CLANG__' code in rtos_freertos_stackings.c to get it to compile with GCC. Unfortunately, after compilation I am running into the same problem as
bbx10node in the
original topic. The output is 100% consistent after several tries.

That actually looks somewhat sane, believe it or not. You probably interrupted the processor at a point where only CPU0 was running, causing all kinds of problems trying to get info from CPU1. Aside from these, OpenOCD seems happy.

Oke, I adjusted the esp32.cfg file and OpenOCD is happy now. Using the Pi-Zero as an RNDIS/Ethernet Gadget, I can now run debug commands from Visual Studio Code on my W10 laptop. Thanks for the help!

Which plugin for VS Code are you using to set up remote debugging? I'm eager to try it, but the only plugin I found was very much alpha quality at this point.

I am currently using just the 'default' ms-vscode.cpptools. Maybe I just don't know what I am missing out on since my previous c experience is limited to the Arduino IDE.
