It seems an extra library is required, located here: https://github.com/ntfreak/openocd/blob/master/tcl/mem_helper.tcl

wget https://raw.githubusercontent.com/ntfreak/openocd/master/tcl/mem_helper.tcl;

I ran into that issue, but the library is included in more recent versions of openocd. I think I was on 0.10.3. I guess the PR linked here just means this will work with 0.10.0, which is more widely available in package managers?

Sorry if this is not the correct place for this but I'm new to all this - I'm trying to follow the instructions here https://airbreak.dev/firmware/ and I'm using wsl on windows as I don't have a linux machine. I was able to get the hardware connected, install openocd (version 0.10.0, I don't know how to get another version).

When I call this command: sudo openocd -f interface/stlink-v2.cfg -f 'tcl/airsense.cfg

I originally got the error: tcl/airsense.cfg:75: Error: invalid command name "mrh"

So I used wget to download mem_helper.tcl. But now I get:

mem_helper.tcl:7: Error: invalid command name "read_memory"

Is there another tcl file to download or am I doing something more fundamentally wrong like the wrong version of openocd

FYI: I worked around this by using Debian instead of Ubuntu. When I installed openocd I got version 12 instead of 10 and then it worked.
