serial program load fails

Other Parts Discussed in Thread: TMS320F28035

hi all,

I am using tms320f28035 device and I want to download program to it serially.

I am using CodeSkin C2Prog software.

I am able to enter in the boot mode.

here is the message I get from console... 


*** PLEASE RESET TARGET IN SCI BOOT-LOADER MODE ***
Connecting with target (autobaud)... OK.
Bootloading... OK.
Please wait...
Connecting with target...
-Chip ID: 0xBF
-Chip Rev: 0x01
OK.
Unlocking target... OK.
Loading... OK.
Connecting with target...
-Flash API version: 100
OK.
Erasing flash... [A] failed (no response)!


as you can see that device connection is ok.(chip id gets detected, however I have no idea how to verify that with datasheet !!!)

And device is able to unlock also.

But i am not able to download the flash.

As the device gets connected I don't suspect hardware.

Can you please share any suggestions?
