The following output from the test connection points at a hardware problem (either with the emulator, JTAG cable or C28xx target):
[quote user="Sunil Kumar Behara"]The test for the JTAG IR instruction path-length failed.
The JTAG IR instruction scan-path is stuck-at-ones.
The test for the JTAG DR bypass path-length failed.
The JTAG DR bypass scan-path is stuck-at-ones.[/quote]Are you able to try a different target or emulator to determine the cause of the error?
