I’ve been meaning to pick up a micro-controller and work on it again. About 5 years ago when I first encountered Arduino, I spent sleepless night learning about it, and creating things from DIY weather station, world clock, light sensor, etc. Fast forward to the current days, I almost forgot everything I learned. But we can always re-learn, or can’t we? Tonight, I found an Stm32 Nucleo F401RE micro-controller, and I want to start by updating the firmware on it (admittedly, this is the easiest thing to do)....

Not too long ago, upgrading firmware on STM32F4-Discovery board required it to be performed on a Windows machine. That annoyed the heck a lot of people, myself included. There’s a very good news for Linux and Mac users. Now, you can do it from your favorite OSes. Since I’m so excited about this, here’s a short article on how to do just that. First download “STSW-LINK007” from <www.st.com/web/en/catalog/tools/PF260217>. At the time of this writing the file is called: stsw-link007....

Having trouble uploading compiled code to K20D50M board? There’s a new firmware that (should) fix this. A few weeks ago, I’ve updated the OpenSDA firmware on my Freescale FRDM-K20D50M to v114 only to find out that it no longer let me uploading any compiled files to the board. At first I thought my board was faulty, but felt relieved to hear that Erich Styger, an mbed expert, confirming this v114 firwmare also affected his K20D50M....
