It does not crash now, but I use different GDB now (the most recent linaro toolchain), and now OpenOCD says: > (gdb) target remote localhost:3333 > Remote debugging using localhost:3333 > Remote 'g' packet reply is too long: > 0000000000000000000000000000000000000000000 > 00000000000000000000000000000000000000000000000000000000000000000000000000000010 > 00000000000000000000000000000000000000000000000000000000000000000000000000000000 > 00000000000000000000000000000000000000000000000000000000000000000000000000000000 > 00000000000000000000000000000000000000000000000000000 It also does not crash with -rtos auto.

However I also tried with CodeSourcery's GDB (a little older) and OpenOCD crashes after connecting with GDB.

I hope that it helps a bit to make RTOS support work for me too... BTW I see that OpenOCD does not want to work with GDB new via command line, but it works perfectly fine via Eclipse's GDB Hardware Debugging... 4\/3!! ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
