I just finished building new inchworm+ programmer. When I tried to conect it to my computer I get whole bunch of errors most of which I do not know what they mean. My MPlab is 7.52.

Here is part of it:
ICD0133: Firmware does not support command (0x1).
ICD0082: Failed MPLAB ICD 2 operation
MPLAB ICD 2 Ready
Downloading Operating System
ICDWarn0054: MPLAB IDE has lost communications with the MPLAB ICD 2. Would you like to attempt to reconnect?
Connecting to MPLAB ICD 2

ICD0082: Failed MPLAB ICD 2 operation

If anybody can help i will appreciate it very much.
Thank you Jirka

I am using serial port COM1, I did reboot after setting FIFO off and both IC's feel cool. Vdd is 4.87V and Vpp is 12.91.

Seems like the firmware is not working properly. If you have a simple Tait or JDM programmer, you could try and program the PIC again with a good hex file.

I tried to download OS from MPLAB and this is the result:

ICDWarn0054: MPLAB IDE has lost communications with the MPLAB ICD 2. Would you like to attempt to reconnect?

If I say yes then it just repeats sequence.

I do not understend this: "Failed to write 10 of 28656 bytes " 877A has only 8K memory doesn't it?

And than:'The operation completed successfully+Download Operating System Failed

Why this "' - USBCOM = 0x0)" when I am using COM1 ?

Thank you for your help

Thank you for your reply. I can program 877 but not 877A. I am in B.C. mountains and it took two weeks to get your kit here.If you point me to right file, if it is possible to use 877 in inchworm+, then I'll try to do it myself.
Thank you Jirka

I will try that.Thanks to all of you.
