Hi all.
If I make the following program:
int main() {
while(1) {
__WFI();
}
}
Then flash-program it and flash-program it again, the second flash-programming
will fail (for me at least).
In order to get my device up and running again, I'll have to run OpenOCD as a
server, issue
> reset halt
several times, until I see something like ...
target state: halted
target halted due to debug-request, current mode: Thread
xPSR: 0x01000000 pc: 0x080002e4 msp: 0x2001c000
-Then I can manually do a flash write_image erase myfile.elf
Is this "wfi-problem" a known issue ?
When things like the above happens, I sometimes get into further trouble; my
debug-adapter won't respond or if I'm very unlucky, my OpenOCD won't quit.
I also often have to ...
1: Shutdown OpenOCD - sometimes by ^C
2: Turn off power to my device
3: Disconnect my lock-pick (or stlink if I'm using that one)
4: Re-connect my debug-adapter
5: Turn on power
6: Run OpenOCD again
... in order to "reset" libusb.
(2 & 3 can be swapped, 4 & 5 can be swapped)
I /have/ to disconnect the adapter, because usblib is still connected to it,
thus it's not sufficient to restart OpenOCD.
Love
Jens
