A configuration script may want to check the reason why examine fails e.g. device has security lock engaged. tcl/target/kx.cfg and klx.cfg is modified to use the new event for testing of the security lock of Kinetis MCU Change-Id: Id1d3a79d24e84b513f4ea35586cd2ab0437ff9b3 Signed-off-by: Tomas Vanek <vanekt@fbl.cz> Reviewed-on: http://openocd.zylin.com/4289 Tested-by: jenkins Reviewed-by: Antonio Borneo <borneo.antonio@gmail.com>
