In circuit serial debugger with ICD-U64 on DSPIC33EP256GP504
PostPosted: Thu May 17, 2018 4:45 pm     Reply with quote

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.
