In circuit serial debugger with ICD-U64 on DSPIC33EP256GP504 |

I am using a board with DSPIC33EP256GP504, and programming with the ICD-U64 (latest HW and FW revisions). I am using compiler version 5.070. The device programs fine and runs, albeit with a few bugs I need to resolve. However I can't get the debug (ICD) mode to work, it comes up with an error stating there are 1447 verification errors, and the likely cause is 'failure to properly erase'.
I have the following fuses set:
Code: |
#device ICD=3
#fuses DEBUG
#fuses NOJTAG
|
Am I missing something obvious?
I have tried different ICD-U64's as we have a few of these, but all report the same error.
Thanks in advance for any ideas or answers. |

OK, I don't use either but I'll take a stab at it...
Does ICD=3, mean it uses the 3rd set of pins to interface the PIC to the debugger hardware ? If so, confirm you've got the correct connections.
I'm sure those famliar with your equipment will respond but it mght take awhile...

Yes, ICD=3 means using the 3rd programming port, and yes I've got the right connections, as i can program and verify the device.
However today I managed to get it working. I updated the Firmware of the ICD-U64 from 3.21 to 3.26, and ran a delete chip from ccs load, then after that the debugger started working. I'm not sure either of these things were really the solution, but for now it is working. |

Recent chips in some cases need really new firmware. I've had a couple recently that needed to be updated to the very latest releases to work. Almost certainly the firmware update was the key fix.
Glad you have it sorted. |
