4 Common Error Codes

This section lists several common error codes that Code Composer Studio shows during a Test Connection operation, an attempted connection, or an attempt to load code to the device. If the problem is not solved by the corresponding debug steps, search TI's E2E™ forum for any other threads with the same error code.

See the How to test your JTAG connection with CCS link for Test Connection instructions, and see also the Manual Launch instructions to manually connect to the device and load code.

Use the following flow when debugging error codes:

  1. Test Connection to verify that the JTAG signals are connected correctly
  2. Connect to the device using the previous instructions for a manual launch
  3. Load code to the device
