5.1.1 Issue 1 - Embedded XDS110 Connection to AM64x Target in CCS

Applicable EVM Revisions: All

Issue Description: On some EVM, the embedded XDS110 (U59) has been shown to fail initial target connection to AM64x target in CCS after first EVM and XDS110 power cycle. No problem exists when using an attached, external emulator over the CTI20 header (J25).

This failure mode can be encountered by following the steps below:

  1. XDS110 USB is attached between host PC and XDS110 USB port (J28).
  2. EVM power is enabled and the AM64x is brought up in no-boot mode.
  3. In CCS, an initial CCS target connection to the M3 DMSC core is then attempted.
  4. CCS errors out with the below dialog complaining of a DAP connection error to the target core.
    1. Hitting retry results in the same error message.

Workaround 1: After the connection issue is encountered, users can unplug the USB host connection to the XDS110 emulator through USB port (J28) and then plugin the USB cable again. This power cycles the XDS110 and clears up the connection error.

Workaround 2: After the connection issue is encountered, users can toggle TRSTSN through the XDS110 debug command-line utility xds110reset found in the CCS XDS110 utility directory.

In the Windows OS installation, for a default installation of CCS version 10.11, this tool is found in the directory C:\ti\ccs1011\ccs\ccs_base\common\uscif\xds110> .

This command can be executed on the Windows command prompt/terminal when the embedded XDS110 is powered on and connected to the host PC. A similar tool is available under the Linux OS install of CCS.
