Other Parts Discussed in Thread: TMS320VC5505

I'm using  the CCS V4.2.4.00033. After loading the program, I find that CCS can't open the memory window. If I do it, CCS will give a error. error is "C55xx: Trouble Reading Memory Block at 0x1 on Page 2 of Length 0x7e: (Error -1069 @ 0xFC) Device memory bus has an error and may be hung. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Release 5.0.429.0) ".

Anybody knows the reasons?

    Hello,

    Is the address location you are trying to view indeed valid memory? Is the debugger memory map enabled? What exact device are you using?

    Thanks

    Hi

    Thanks for the post.

    I uses the TMS320VC5505  ezdsp and I can make sure that the address is valid. Two days ago, it can run correctly. But now  it has a error. Besides the address is the peripherals'  registers. About memory map, I don't know where it is and how to enable it. Can you tell me how to do it?


    Thanks again,

    Regards,
