Just ran into a similar problem. I have several M52235EVB boards and,
having such good luck getting the uTasker server software running on them,
attempted to do the same on my M52233DEMO boards.
From the CW 6.4 IDE, I could attach to the on-board BDM interface but,
when I attempted to erase flash, prior to loading the uTasker srec file,
it complained that it could not write to memory.
-target processor was 5223x
-connection was PEMICRO-USB
-target initialization cfg file was C:\Program Files\Freescale\CodeWarrior for ColdFire V6.4\E68K_Support\Initialization_Files\M52235EVB_PnE.cfg
But, I noticed that the right flash xml plugin file was not set (via LoadSettings button).
You have to navigate to these files in C:\Program Files\Freescale\CodeWarrior for ColdFire V6.4\bin\Plugins\Support\Flash_Programmer\Coldfire\???.xml.......(of course!)
That did the trick...flash erased, uTasker loaded, app runs just as on the M52235EVB.
Of course it didn't help that whoever manufactured these kits for Freescale put the
wrong documentation in both kits (what's a MPC5566EVB manual doing in a M52233DEMO kit?)
and left out CW registration cards on BOTH M52235EVB kits....but guess I'm just being picky.
Cheers,
McP
