Compiling and running simtrace firmware with a recent toolchain - simtrace

9 Mar 2018

Hi,

The simtrace firmware is in the OpenPCD git repository at:
...
  git://git.osmocom.org/openpcd.git 
I used the last revision at the time of writing:
...
  dc2983d firmware: Makefiles: enable changing toolchain

With a fairly recent gcc version:
...
  $ arm-none-eabi-gcc --version
 arm-none-eabi-gcc (Arch Repository) 7.3.0

 This is free software; see the source for copying conditions.  There

 PARTICULAR PURPOSE. 
Compiling the firmware the usual way works, with many warnings:
...
  $ make BOARD=SIMTRACE DEBUG=1 TARGET=main_simtrace \
 CROSS_COMPILE=arm-none-eabi- [...]

Installing that firmware went fine:
...
  $ sudo dfu-util -d 16c0:0762 -a0 -D
./main_simtrace.bin -R
 dfu-util 0.9

Here's what I have on the serial port:

So it gets reset in a loop.

I can get it to work with the following diff:
