CCS/TMS320F28377D: memory map error while trying to program the device

Part Number: TMS320F28377D

Tool/software: Code Composer Studio

Hi

i try to program my board (new board) with the CCS debug mode, but i get the following error:

c28xx_CPU1: file loader: verification falied: values at address 0x0...082028 do not match  please verify target memory and memory map.

i tried to program the board with the Uniflash application and it works.

any ideas?
