Hello,
after loading the OpenSDA firmware
http://www.keil.com/appnotes/docs/apnt_232.asp
and setting up user access to the HID device
/etc/udev/rules.d/99-hid.rules:
# Allow access to OpenSDA
KERNEL=="hidraw*", ATTRS{idVendor}=="c251", ATTRS{idProduct}=="f002",
MODE="0666"
and enabling cmsis-dap
./configure --enable-cmsis-dap
and recompiling, I can start OpenOcd on the frdm-kl25z board.
Trying to attach to the debugger however says:
Info : accepting 'gdb' connection on tcp/3333
Warn : Cannot communicate... target not halted.
Error: auto_probe failed
Error: Connect failed. Consider setting up a gdb-attach event for the target to
prepare target for GDB connect, or use 'gdb_memory_map disable'.
Error: attempted 'gdb' connection rejected
After connecting to the device in telnet and giving the halt command, gdb
can connect, even after stopping gdb/openocd and restarting
Adding a halt command in the gdb-attach event like
$_TARGETNAME configure -event gdb-attach {
echo "Halting target"
halt
}
helps, but this will alway halt the device on gdb connect. Is this the right way
to go?
Bye
