TMDSCNCD28335: I have error after execution of program.

Hi Virendra,

Here is some info on how to debug the error that you are seeing.

Generic FTDI failure

This is a very unusual error and its exact reason is not entirely characterized. It is reported on the following e2e forum threads:

• https://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/564965
• https://e2e.ti.com/support/microcontrollers/c2000/f/171/p/424273/1514372#1514372

This error is generated by TI's USCIF driver or utilities.

The value is '-150' (0xffffff6a). The title is 'SC_ERR_FTDI_FAIL'.

The explanation is: One of the FTDI driver functions used during configuration returned a invalid status or an error.

In this case, a procedure of resetting the JTAG debugger using dbgjtag was reported to being effective to restore communications.

1. run the 'Test Connection' script in the CCSv7 target configuration tab → FAIL with log shown in previous post (error code -150)
2. run dbgjtag tests WITH reset (integrity, broken, path length, given data) → all tests FAIL with same failure code (error code -150)
3. run dbgjtag tests WITHOUT reset (integrity, broken, path length, given data) → all tests PASS
4. run dbgjtag tests WITH reset (integrity, broken, path length, given data) → all tests PASS
5. run the 'Test Connection' script in the CCSv7 target configuration tab → PASS
