Blackhawk XDS100v2 ARM does not reset TM4C1237D5PM

Hi,

I'm using the Blackhawk XDS100v2 ARM JTAG Adapter to load my program on the TM4C1237D5PM via Code Composer 6.

I have a hw watchdog on my board which is resetting the target once I try to load my program on the target. The Adapter should reset the watchdog to prevent the watchdog from resetting during the program load. I probed the system reset line (nSRST) of the JTAG Adapter and it is not pulled down before loading the program.

(The test reset line (nTRST) gets pulled down)

I tried to find a setting in CCS6 to trigger the system reset line before loading the program. Since I'm using the ARM version of the Adapter I can't use the EMU0 and EMU1 pins to enable the wait-in-reset mode.

Does anyone know a way to trigger the system reset line when load a program in CCS6?


Thanks,

Alex
