STM32F4Discovery examples for GCC on GNU/Linux
TweetSTM32F4DISCOVERY is an ARM Cortex M4 development kit.
I don’t plan to write again a toolchain setup instruction for this board. You can install toolchain and flash tool as per instructions provided in the below link
http://recursive-labs.com/blog/2012/05/07/stm32f4discovery-chibios-linux/ Read the section – Building the toolchain on Debian using “Summon Arm Toolchain”
While installing the toolchain I got an error zlib.h: No such file or directory. On a Debian system you can remove this error by issuing apt-get install zlib1g-dev
The ARM toolchain is build using summon-arm-toolchain script. This toolchain also installs a free GPL V3 based firmware library known as libopencm3.
As I mentioned above, the summon arm toolchain will also install libopencm3. libopencm3 generates some header files during installation. These header files needs python yaml support. The build might stop because of this. You can fix this issue by running apt-get install python-yaml
You can find examples for STM32F4DISCOVERY from https://github.com/libopencm3/libopencm3/tree/master/examples/stm32/f4/stm32f4-discovery

LPC2148 (ARM 7) Test bench setup
Tweet
This is my LPC2148 (ARM 7) test bench setup.
The LPC2148 header board was bought from Rhydo Labz. You cannot directly power up and start to use. It lacks communication interface. To flash the controller, you need a serial port or a JTAG port. Since this board doesn’t have these port connectors, you need to solder them. So it might be hard for a newbie.
Instead of this board, you can try the BlueBoard which has all the port connectors. I will recommend this for a newbie. I hope that board is worth for its price.
The next thing which you need is a power supply to power the board. You can build your own power supply (If someone needs to know how to build a power supply, I will write a tutorial. But please put a comment in this post saying that you need the tutorial.) ,or you can buy 5V DC power supply (adapters).
Once the board is powered up, it can start to execute your code in its memory. But a fresh controller wont be having any code in its memory to execute. You need a programmer to load the code into its memory. But the LPC series controllers have built-in serial boot-loaders. These boot-loaders can get the code from the serial port and write into its flash memory. So you don’t need a programmer.
To program the controller using the serial boot-loader, you just need to connect the controller to the host PC and the host PC needs to run a serial programmer software. You can get a lot of serial programmer software for LPC controllers. Some of them are
So thats all. Power up the board and connect the serial port to the controller. Run the serial programmer software in the PC. You controller will execute the code flashed into its memory.
But wait. From where you can get the hex file to flash into its memory? Its simple. You just need a cross-compiler. To the cross-compiler, you just need to feed your C source file. It will compile and give you *.out files, which later can be converted into *.hex files.
I will soon try to post a wiki page about how to compile and flash the code into the memory.
Electronic Design and Fabrication with gEDA
Tweet“Electronic Design and Fabrication with gEDA” is my first article in LINUX For You Magazine.
This is the first time I am forgetting to blog about my article. Actually it was published in last month(NOVEMBER 2009) issue. Please read it if possible.
This article mainly gives a quick introduction about gEDA. I have also given some snaps of my designs.
