I am just updated to svn 1881 to use with my STM32 and jlink(yellow v6.0). I had been using 1183, which worked every time, but was unbearably slow. Revision 1881 is lightning fast compared with the old revision. I am however seeing a few issues.
It takes 5 or six tries to get my program to download into flash. I either get a segmentation fault at startup or an error while writing the code to flash. I have attached examples of both problems below along with my configuration file. I am away this weekend but would be able to get a debug build running to try some things out next week. Great work on the speed up! $ sudo /usr/local/gnu-arm/bin/openocd -f ../GNUTools/openOCD/newLPM.cfg -c init -c "sleep 200" -f flashAll.script -c "reset run" -c "shutdown" Open On-Chip Debugger 0.2.0-in-development (2009-05-22-09:47) svn:1881 BUGS?
