ADSPSC835W-EV-SOM, No autobaud response for CCSFP tool

Thread Summary

The user encountered a 'No autobaud response' error when attempting to boot the ADSPSC835W DSP processor using UART0 and the CCSFP tool. The issue was resolved by following the board modification steps in Chapter 3.11 of the CrossCoreSerialFlashProgrammer_UsersGuide.pdf and adhering to the boot procedure in Chapter 3.10.1.

Product Number: ADSP-SC835
Software Version: CrossCoreUtilities-Rel1.8.0,

The ADSPSC835W DSP processor can boot using UART0, which corresponds to the 0x3 hex-switch position. After pressing the reset button, the processor should enter the UART-BOOT stage.

To download data in this mode, a special tool called ccsfp—located in the CrossCoreUtilities-Rel1.8.0 package—is used. The procedure involves three simple steps:

  • Select the appropriate COM port

  • Choose the desired LDR file

  • Click the Start button

However, this procedure failed due to a "No autobaud response" error. After a few second the fault red led indicate the error.  I kindly ask for help. The CCSFP software and booting in UART mode work without any issues with the EV-SC594 board.
