TMDSEMU110-U: XDS110 Debug Probe toogle reset fail

The xds110reset does not affect the TRST pin. Per documentation, it affects the nRESET or nSRST pin, depending on which adapter you are using.

The reset line controller is the board or system reset pin on the debug header. Asserting this pin should cause a hard reset on the target device, similar to pressing a manual reset button. On the TI 20-pin header, this is pin 15 (nSRST). On the Cortex-M 10-pin header, this is pin 10 (nRESET). And on the ARM 20-pin header, this is pin 15 (nSRST). This reset is not available on the TI 14-pin header.

The XDS110 is 20-pin header.

Tried on pin 15(nSRST). There was not votage level(zero volt) change as well.

Have you tried just issuing "xds110reset" or "xds110reset --action toggle --delay 3000", without the serial number specified? From user guide:

Examples: How to reset the target using an XDS110:

xds110reset

xds110reset connects to the first XDS110 it finds. It then toggles the board reset line, holding it asserted for 50 ms.

How to toggle the board reset, holding asserted for 3 seconds:

xds110reset --action toggle --delay 3000

The given delay is the time between asserting the reset and releasing it. The --delay option is only used when the --action option is toggle.

Same result.

Let me see if our CCS team can comment on this one.

Hi Alan,

I am working with engineering on this. I'll keep you posted of any updates.

Thanks

Hi Alan,

Just a quick (non)update that we are still looking into this. Sorry for the delay.
