Is it possible to use the ICD-U64 to program a PIC24HJ128GA204 using a hex file generated by mplab 8.76 ?

CCS load is able to program the chip using this hex file (generated by mplab 8.76) but pro ...

Not sure if this is a familiar topic or not.

I'm using the CCS TCPIP stack for tx/rx udp packets on PIC18F67J60 and it works quite well enough.

But when I have had coding issues, and set brea ...

I toggle an LED in my while(true) loop.

In some act of desparation, I took a 67J60 that I ordered along with the extra 86J65's. This part is on the CCS eval Ethenet board, and works great.

I ha ...

I would expect 1, or 2, but I've not found either. Nor #3 having checked with scope.

For #5 I do have more 86J65's arriving today. Will try another one.

So far #6 is winning Smile

Very similar to what I use with the ENC28J60 on another design.

And for the e ...

For this 3.3V project to get a few extra I/Os I've used the PIC18F86J65 Ethernet chip rather than the 67J60 (that does work). On the proto I've got all the Vcc, Vss pins (exactly the same set off pins ...

Thanks for the reply- I will check out your suggestions today.

I'm a bit baffled by this problem, having used PIC controllers for several years.

Running the PIC18F2525 with ENC28J60. UDP only IP's all hardwired for now. Adjusted the example code so that I can ...

OK, problem resolved itself soon after posting Smile

I can hardwire it in

I'm using the CCS ENC28J proto board. Not sure how the dest mac address is set.

Ethereal indicates that it is currently 39:01:01:04:02:7b?

I am using loader.c - this works fine for small programs with addresses < ~0x1500, and has worked fine for any size program in the past. The acctual program is less than 0x7000

Another tiresome loader question I'm sure.
