PC pointe a error value after power on

jian zong1

hi,

my 6678board is not EVM board . yesterday i connected core0 and opend the memory watch windows . i found the value in DDR was always changing and the PC value pointed an address 0x70366DD8 . i think the PC value should be ox20000000.

after i loaded an .out file to core0. and ran it . the data in ddr still appeared . i could not run my program normally .

so how to explain the phenomenon and make it pointer a normal address?

IS the dsp running a flash prgram ?

Hi,

Have you using .gel file for initalize the 6678 board? If you using .gel file means that will initalize the DDR. For more information refer EVM .gel file in MCSDK package.
MCSDK Path: "\ti\mcsdk_2_01_02_06\tools\program_evm\gel\"

If you want to use DDR memory on your appliction means you need to initialize the DDR memory before the DDR access.

Thanks,
