The eclipse based CodeWarrior for MCU10.2 comes with many unique extensions of the eclipse platform, implemented by Freescale. One of these featured mentioned in my post is the ability to inspect the registers in an offline mode: The Offline Register view. How is this different from the Registers view?
My post in “An error occurred…”: Applied Debugging Rules gives some hints about how to isolate and solve some debugging problems. But here is a case where the tips did not help: I had this dialog with “Failed to resume target process” for my HCS08 project again:
As shown in Tracing FreeRTOS with a Hardware Probe: I have a nice hardware probe to trace out events from my application. But what about to use the target memory as trace buffer? New devices have much more on-chip memory, so this could be an attractive option. That was on my list of future extensions, but then the news came in: Percepio announced their collaboration with FreeRTOS+Trace: exactly what I needed!
It is using the same concept as the FreeRTOS Trace Probe: the trace hooks provided by the FreeRTOS API. But instead streaming it off the target as with the FreeRTOS Trace probe, it is using a RAM buffer on the device. The real cool thing is: the Percepio trace viewer is very, very nice!
I was running into that dialog while opening my S08 project:
Target Task Error: “Error importing task.”
Hmm, that’s weird: the target task framework complains about a target task, but in my project I’m not using any target tasks?
Using an RTOS is an excellent thing: it provides services and allows to scale my application. But it adds complexity. With many tasks, queues and semaphores it is hard to have an overview what is going on. To get visibility, Martin Bucher has developed in a bachelor diploma work the FreeRTOS Trace Probe.

Creating an eclipse managed make project with MCU10 is easy: Starting the wizard with File > New > Bareboard Project and after a few clicks I have a project. I don’t need to worry about all the files in the project structure, until……..well, until I need to put the files into a VCS.
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
