Hi Bernie. I have sent you directly a flash driver upgrade for the CodeWarrior / HI-WAVE debugger. The driver gives the possibility to program directly from...
And don't you have the advantage that XGate runs effectively parallel to S12X, so you can have one doing half the work at the same time the other one does the...
The method below would it work for the S12X? If it does not then what is it? I am trying to program S12X in linear memory map but would not work. ... $4000 to...
Hi Gilles, I got your file and put it in the correct folder. I changed the files as follows: NAMES END SECTIONS RAM = READ_WRITE 0x1000 TO 0x3FFF; /* unbanked...
It turns out that I was setting the prescaler value in ATDCTL4 to 0 for a bus clock frequency min-max of 1-4 MHz and this was causing a problem. I changed the...
... Yeah, but. In my application, the XGATE has to run deterministically for long stretches. I have to be very careful what I let the CPU do so that it doesn't...
Hey. Is there an initialization sequence necessary to be able to read EEPROM (byte-erasable) on reset? Here's my situation: MC68HC912B32 microcontroller. 1....
I would guess that the additional copy code generates enough delay that you are not getting to your code which disables the COP. In BDM mode the COP stats up...

Hey Dave, thanks a lot for the reply. The very first thing the code does is shut down COP though. And when I remove the copy routine from the code, it works...
