Texas Instruments XDS110 User Manual page 18

Functional Description and Operation
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.
xds110reset provides the following features:
• Toggle the board reset with configurable delay.
• Assert or deassert the board reset line.
• Choose which XDS110 to use by serial number
Installation Path:
.../<CCS Install>/ccs_base/common/uscif/xds110
Usage:
xds110reset<command> <...>
Supported commands:
• -a <NAME>, -action <NAME>
Choose an action to perform. NAME may be assert, deassert, or toggle. If not specified, toggle is
executed by default.
• -d <VALUE>, -delay <VALUE>
Set the asserted time for the reset toggle in milliseconds. Has no effect if action is assert or deassert. If
not specified, delay is set to 50 ms by default.
• -s <TEXT>, -serial <TEXT>
Select the XDS110 probe by serial number. TEXT is the serial number to use, up to eight characters. If
not specified, the first XDS110 found is used.
• -h, -help
Show help for these commands, and exit.
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.
3.7.3.2 Firmware Maintenance Utility - xdsdfu
xdsdfu is a command line utility that provides several features for examining and maintaining the firmware
of the XDS110 debug probe. While the XDS software stack includes an auto-update feature for ensuring
the latest firmware is always flashed, the user may need to manually examine or update the firmware.
xdsdfu also allows the user to view and set the XDS110 probe serial number.
xdsdfu provides the following features:
• Report the XDS110 firmware version and serial number
• Place the XDS110 into flash programming mode (DFU mode)
• Download the bootloader into the XDS110
• Download the firmware into the XDS110
• Set a new serial number into the XDS110
• Reset the XDS110 to restart the firmware
