openocd+gdb combo

openocd+gdb combo

[Schneider, Maximilian]

Hello,

I have written a relatively complex but very useful external loader+gdb python script for a piece of memory connected to one of the many chips we use.
I can now use openocd to connect and subsequently gdb with the aforementioned loader and script to read/write/erase !

However It is still a pain to have to start an openocd session before being able to launch the gdb command.

Is there a known way to package openocd and gdb together so that I can get convenient calling conventions like bellow?
./read_the_thing > memory_dump.bin

How would you recommend creating portable installations of gdb so that they can be shipped quickly to the unfortunate windows users?
I can imagine writing an extra tool that manages the sequencing of openocd+gdb but I would need executables I can run without installation to make it palatable for my colleagues.

Best Regards,
Maximilian Schneider

I was facing similar problem a year ago. Took me a bit to figure
out how to make a .zip you can download, unpack wherever you want 
and use, including working python.

If you think it would help, I can try to extract the build script 
from my CI and share some time later this or next week.
