When I write the same image to a STM Primer using RFlasher 7, it only takes ~3 seconds. I also tried to use OpenOCD's RLink interface: 7.241484 kb/s. Much slower than the native RFlasher application. BTW: I also had a "too many retries waiting for DTC status" problem with OpenOCD's RLink interface. Setting the retry count to 10 in rlink.c:526 fixed the problem (maximum used was 7). I'm using a cygwin build on Windows XP SP3. Could you fix that in svn? _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
