I’ve been using the GCC ARM Embedded toolchain for STM32 development on linux for a while now. It’s maintained by ARM, it’s available for linux, windows and osx, and it’s just a zip of binaries. Untar, add to your path, and you’re golden. With the new 4.7 release (2012q4) it includes some decent code size improvements, and is generally just a one stop shop for getting a toolchain.
However, the linux builds don’t have python support in GDB. This isn’t necessarily a bad thing, but people are starting to put together some nice tools that plugin to GDB that rely on python support. There’s some experimental SWV/SWO support, there’s some neat support for printf without printf and, what I’m trying to do, dump a lot of data buffers straight out of ram on the target device for analysis in python.
So, I tried building it myself. I first tried just downloading recent gdb sources and adding python support, after setting the target to arm-none-eabi. but….. that didn’t play well with openocd, so I went back to trying to build the G-A-E provided sources instead.
Here’s what I needed on Fedora 17 x64
This then replaces step 5 from the provided instructions…
$ cd [extracteddir]/src [dir]/src$ tar -xf gdb.tar.gz [dir]/src$ cd gdb ./configure --with-expat --with-python --target=arm-none-eabi make -j5
That got me a working gdb with python support…
