Other Parts Discussed in Thread: TM4C1294NCPDT
I was testing the drag-n-drop configuration of the XDS110 on the AWR2944EVM by using the following command:
xdsdfu -c 4 -r
This worked but now I cannot put the device back into configuration 1 (default) as I cannot get the XDS110 into DFU mode.
I have read the following in the readme:
In the case that your XDS110 fails to enumerate as a USB device, or it fails to enter DFU
programming mode, you can attempt the following steps to force it into DFU mode to recover:
1. Ground the JTAG TDO pin of the XDS110's Tiva CPU. This is pin 97 on the 128 pin
device. (Check the TM4C1294NCPDT datasheet for the pin location; it is located on a
corner and easy to access.)
2. Unplug and re-plug the XDS110 into the host computer while the pin is grounded.
3. The XDS110 should now be in DFU programming mode.
4. Remove the connection to ground while the XDS110 remains powered.
5. Use the xdsdfu utility to update the firmware as detailed above
Is pin 97 accessible on the AWR2944EVM to ground it? Is there any other way to get the XDS110 back into a default state?
Thanks,
Mark
