Ok, you are probably new to Eclipse, and want to do the fun part: Creating an Eclipse Processor Expert project in CodeWarrior for MCU10.2. Cool! Here are some steps and tips to make it smooth from the beginning…
I have mentioned in MCU10.2 released a new feature in CodeWarrior: support for the USB Universal Multilink FX from P&E Microcomputer Systems. Two Multilink FX arrived last week at the University, and finally I had my hands around it. The first thing which came to my mind when I saw the picture of the device on the P&E website: the black boxes are back!
Can I hope for a “Special FX Edition” in that box with cool sunglasses and a flash stick to erase and reprogram FLASH memory of microcontrollers? That would definitely make the flash erasing and programming easy and fast, as in the movie. 🙂

At the University the lectures started, and as well all the bachelor diploma and industry projects. So I am running out of my TWR-MCF52259 boards as they are used by my students. No problem, as I have one remaining board in my shelf. I plugged the board into my machine, but YIKES! Look at this:
Chinese OSBDM?
Yikes! Flashing failed!
All I wanted to do was to re-flash my boot loader on the TWR-LCD board with the ColdFire V1 MCF51JM128 on it. Trying to this gave me a P&E Connection Assistant dialog: Continue reading
Ahhrg! Again, my microcontroller stopped in an interrupt. And I have no clue why?
Using Processor Expert in MCU10 is a great thing as it takes care about the vector table. Usually the default settings for code generation are fine, but not in my case here. If you run into a spurious and unexpected interrupt, you stop in the Cpu_Interrupt() handler:

I use a Intel processor to write this text, and this processor is is using Little Endian for the byte order. This is about Endian, not Indian :-).
Many processors I have programmed were Big Endians. With the addition of Freescale Kinetis (an ARM Cortex M4) and DSC in MCU10.2, I have a daily mixture with Big Endian (S08, ColdFire, …) and Little Endian (DSC and Kinetis).
The term “endian” is described nicely in the IEN 137 written 1980 by Danny Cohen:
“ON HOLY WARS AND A PLEA FOR PEACE“.

I just have run across a problem: I received a project for the S08QE128, and when I started a debug session with MCU10.2, the debugger was showing “no source available”. Ahhrg. Something must be wrong…
No Source Available?
Well, at least I can debug on assembly level. But this is not the point. I have the sources, but somehow the debugger does not find them?
