HI,
I tried following the suggested article and this time I had different problems. Previously I had done the same thing following a similar article and the ESp32 was being recognised ok by the openocd on the raspberry pi. This time, I am getting a different error which I forgot to write down.
Unfortunately I have had to stop trying for a short time due to work. I will try again in a few days and report back.
regards
Justin.
This morning, I decided to buy a proper debugger, but the raspberry pi is still something I would like solve eventually.
With custom gdb mode, i couldn’t find where to enter in the target remote command. I tried the -interpreter mi argument though with both options without success.
With the gdb devices, this ( see below ) is what gets reported under windows when I tried the sysfsgpio-raspberrypi interface (The command is basically the same as the one I run on the raspberry pi). I noticed when I build openocd, I have to use the –enable_sysfsgpio for make as it is not preselected. There was another device in the VisualGDB list, but I was trying random ones to see if any expected a network address, and can’t remember which one.
With VisualGDB, I am assuming that the openocd running on the PI is basically acting as a GDB server. I can understand why that one needs the sysfsgpio-raspberrypi.cfg interface configuration in order to communicate through the gpio pins, but why does the openocd running under VisualGDB (windows 10) need to know about it?
