Perhaps this helps, perhaps not, but the Cortex-M architecture from ARM defines, as required, a build in debug unit. I can build a standalone JTAG/Development tool for it[1] on a $3 breakout board, and program/debug it for free using GCC. It has been a pleasant side effect of competition in the embedded space that proprietary (and expensive) tooling has become a problem for getting a chip adopted and so there is more pressure to support open source solutions.
