Hi Shankari, Thank you so much for your reply. I did as you asked me to do, But still I got this error message "arm_A15_1: Error connecting to the target: Connect to PRSC failed" Then I realized that I have been connecting the wrong target core ************************************************************************************************************* First of all, In the Code Composer Studio - Device Debugging menu, For 66AK2xx devices The core name I think I should connect is Texas Instruments XDS2xx USB Emulator_0/arm_15_0 instead of Texas Instruments XDS2xx USB Emulator_0/arm_15_1 Because I think there is a core name difference betweeen 66AK2xx devices and other devices(Ex: TCI6638K2K device) 66AK2E05 Device Debugging core options TCI6638K2K Device Debugging core options Note : 1st image is the core options for 66AK2E05 device and 2nd image is TCI6638K2K device As you can see, the TCI6638K2K device core name stands as coretexA15_1, coretexA15_3, coretexA15_5, coretexA15_7 whereas in 66AK2xx devices its arm_A15_0, arm_A15_1, arm_A15_2, arm_A15_3 So I should select arm_A15_0 core for 66AKExx devices ??? If I select that core I can able to load U-boot binary successfully from CCS :) Please clarify me whether the things I said regarding the core selection is correct and correct me if I am wrong. Cheers. Thank you sooo much for the steps. Regards Sarjoon.
