I have been using a few E28 boards from across the way with great success. I now have one which is behaving oddly and I suspect that I have corrupted the MM firmware as I have been more adventurous in using memory access.

I can see and access the E28 using MMedit on com4.

When I run pic32prog as per following it reports "target not found"

pic32prog -d ascii:com4 micromite_V5.04.05.hex

I have pressed the button and both leds are on. what am I doing wrong?
I have tried 2 different E28 boards. One a virgin still with the test prog insitu.

Cheers, Alastair

Have you tried using Rob's excellent GUI front-end for pic32prog.exe?
You can download this from my website here:(with Rob's permission to host it)
PIC32PROG GUI
(scroll down a bit...)

REBOOT YOUR COMPUTER - A full power-off and on again reboot.

Bill Gates often seems to get his USB handler confused, and I have found that a reboot will clear this issue a-lot of the time. This is if you are plugging in and removing USB-serial adaptors. At a certain point, Windoze just refuses to see the COM port at all, and just reports: 'The USB device has malfunctioned and Windows does not recognise it.'

Reboot, and the problem goes away.

Now, I know you say you can talk to it fine on COM4, so that does not seem to be the issue, but I want to be sure.....

G
I was using pic32prog via the command line as per my first post.

Thanks for the link to the gui. This looks a lot like the MPlab interface and is much easier and reduces the likelihood of spelling mistakes.

I have been out & about today and just returned tired & highly likely to s..ff up anything I try, so it is for first thing in the morning.

thanks again.

Cheers, Alastair

Rob,
Yes. Sorry for being slow in posting.

You are responsible for my success. In the early morning I tried again using the command line approach. No go.

I then used your GUI shell and had instant success. The command line insisted there was no target but your routine found it with no change.

Would like to know what the problem was but too much to do to spend time atm.

thanks
alastair

ps reflashing did solve the E28 problem so I must have poked somewhere I shouldn't !Edited by Alastair 2017-10-16
