thanks again Pedrhom Nafisi.
for currently i managed to work in ros2 the driver with xWR6843AOP mmwave radars.
but while upgrading to latest version from the radar_toolbox_1_20_00_11.
it works and crashes.
i wish to use updates version to use the software reset command.
and if possible to use from that radar toolbox the obstacle detection example. that also crashes.
thanks for you help until now.
