Hi,
Just for the kicks I decided to try cross-building for arm-none-eabi
with newlib.
Basically, LIBS="-lc -lnosys" ./configure --host=arm-none-eabi,
disabling eventloop and file jimtcl modules (and making its final
linking step manually since it doesn't honour LIBS), adding few stubs,
I got it built and linking. Neither TCP/IP stack nor USB ACM are
included but adding lwIP for ethernet version or libopencm3 usb
library for a USB variant wouldn't be too hard.
The conclusion so far: full OpenOCD seems to be too big to fit
embedded flash of current commonly used microcontrollers but it also
provides unmatched functionality. Sacrificing some features it can
probably be made to work on 1M devices such as STM32F40[57]; an
STM32F427 (2M) board might be able to run it all.
