Step-by-Step: Updating OSBDM/OSJTAG Debug Firmware

Posted on by

While new Freescale boards come with the OpenSDA debug firmware, I still students using boards with the OSBDM/OSJTAG. And with new CodeWarrior tools, it might be that there is a new OSBDM/OSJTAG firmware, and when I download to a board with an older firmware, the tool will prompt me to update the firmware. To me, after doing this several times, not a big deal. But for someone who sees this the first time, it might not be that easy. So to avoid any further questions, here we go with a step-by-step tutorial how to update the OSBDM/OSJTAG firmware.

So I have a graphics driver for a Nokia display (see “Zero Cost 84×48 Graphical LCD for the Freedom Board“), I have a joystick shield (see “JoyStick Shield with the FRDM Board“) and I do have a Freescale Freedom board: why not creating a simple game for it? Snake!

Replicating an Eclipse Update Site for Offline Usage

In my post “Constructing a Classroom IDE with Eclipse for ARM” I outlined how to build a DIY Eclipse distribution. That way I can build an archive/zip and distribute to my students: it saves them a lot of time, and they do not need to download things from the internet themselves, as I can give them the thing on a memory stick. But what if I want them to give them the update site files for offline usage too? For example CodeWarrior has an online update site:

How can I make a local copy of it to use in my classroom?

For some time I’m using the Nordic Semiconductor nRF24L01+ transceiver successfully in many projects (see “Tutorial: Ultra Low Cost 2.4 GHz Wireless Transceiver with the FRDM Board“). Since that tutorial things evolved a lot with the introduced RNet Stack. To honor the popularity of the Nordic Semiconductor nRF24L01+, Freescale has put a socket on the FRDM-K64F board. So time to make a new step-by-step tutorial how to use the nRF24L01+ with the FRDM-K64F.
