Flashing the M52223EVB - Connection Problems

[PopsStack]

I have been trying for some time now with no success. I have tried flashing both Stationery built code as well as the CMX provided USB Mass Storage stuff to the M52223EVB (Rev B Board). I have religously followed (I think) the Targeting Coldfire (PDF) document.

Each time I try do an erase I get a message saying failed to write - error in connection. So I presume it can't be a badly built project cause the erase must happen before attmepting to load the Flash.

I then tried to use the Hardware Diagnostics option - I get:

" Connect Failed : Can't conenct to PE micro via USB "

There must be something simple that I am missing out on.

Does the J1 jumper of BDM_Config or JTAG have anything to do with this. I have tried both - same story.

All my code generated under Console Debug gets things like the PIT, ADC etc running quite nicely.

Maybe I have not read an important document prior to this??????

That tall building down the road looks like a good option - I am getting desparate.

I got very brave and did some serious fiddling - used the 52221 XML file - noting that this one had diffierent mem start address - then did an erase - I nearly fell off my chair.

Then tried to use the 52223 file - also worked. Very confused.

Maybe I should manually change the mem address settings in the 52223 file to start at 0 and keep the rest to look like the 52221 file.

Once I had managed the erase I loaded the USB Mass Storage stuff - it does not see the memory stick when I do a Dir etc nor recognizes the connection - are there any jumpers that I need to change other than the Host one.

OK, let's try this: go to the flash programmer (Tools | Flash Programmer). Select the Target Settings panel. Choose 5222x from the Target Processor pull-down menu, and PEMICRO_USB from the Connection pull-down menu. Now select the Erase / Blank Check panel and try to erase the memory.

Note: I went to the pemicro web site (www.pemicro.com) and downloaded their drivers and installed those. I don't have a Coldfire board, so that's about as far as I can take this. HTH. Sorry if you've covered this ground already.
