Debug DM385 issues by using CCS5.3

I am using CCS5.3 to debug the DM385, but I always had a problem below:

CortexA8: Trouble Reading Memory Block at 0xffffffd0 on Page 0 of Length 0xd: (Error -1205 @ 0xFFFFFFD0) 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). (Emulation package 5.0.872.0)

CortexA8: Trouble Reading Memory Block at 0xffffffd0 on Page 0 of Length 0x30: (Error -1204 @ 0x3D5B) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.872.0)

CortexA8: Error: (Error -1204 @ 0x3D5B) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.872.0) CortexA8: Unable to determine target status after 20 attempts

CortexA8: Failed to remove the debug state from the target before disconnecting.  There may still be breakpoint op-codes embedded in program memory.  It is recommended that you reset the emulator before you connect and reload your program before you continue debugging

Need help. Thanks.

    Hello,

    Please provide more details on how you got this error message. What exactly were you doing before this error message happened?Also provide which emulator you are using.

    I'd also suggest updating to CCSv5.4 and see if that helps.

    Thanks

    Hello,

    I am new to CCS and the DM385. I am trying to configure CCS5.5 for debugging the DM385 and I am having similar problems.

    Since the DM385 doesn't show p in the list of targets, how should CCS be configured for this device? I aI814x should be selected as the target for programming the NAND memory but when I try to test other simple programs, it gives me errors writing to the A8 core.

    Any help would be appreciated.

    Thanks
