Getting Started with Infineon XMC4500 Relax Lite Kit and DAVE 3 IDE

Infineon Relax Lite Kit is a 10 Euros development kit based on Infineon XMC4500 Cortex M4 MCU with 160 KB SRAM and 1 MB flash, and featuring 2 USB OTG ports for debugging and powering up the board, 3 buttons (including reset), 2 LEDs, and 2 headers (through holes) giving access to the signals from the MCU such SPI, I2C, I2S, UART, CAN, ADC, DAC and PMW. The kit if available online via Hitec, but unless you live in Germany, this is not an interesting option, as international shipping costs over 100 Euros. So you’d better check local distributors in your country. The package only comes with the board, and you’ll need a USB to microUSB to power the board. To get started, simply connect the board via the USB cable to one of the USB OTG connectors, and to a Windows PC. The power LED (green) should lit up, […]

Linux 3.7 Release

Linus Torvalds has announced the release of Linux Kernel 3.7: Whee. After an extra rc release, 3.7 is now out. After a few more trials at fixing things, in the end we ended up reverting the kswapd changes that caused problems. And with the extra rc, I had decided to risk doing the buffer.c cleanups that would otherwise have just been marked for stable during the next merge window, and had enough time to fix a few problems that people found there too. There’s also a fix for a SCSI driver bug that was exposed by the last-minute workqueue fixes in rc8. Other than that, there’s a few networking fixes, and some trivial fixes for sparc and MIPS. Anyway, it’s been a somewhat drawn out release despite the 3.7 merge window having otherwise appeared pretty straightforward, and none of the rc’s were all that big either. But we’re done, and […]

Open Hardware System on Module Project

“JM” has started working on a system-on-module project with the goal “to create a whole range of SoM boards and motherboards that can handle a large number of embedded projects”. He has just released schematics and layout files created with Kicad for a dual NXP LPC1764 SO-DIMM module and the baseboard under GPL3 license. The next goal is to release an AllWinner A10 SoM and corresponding baseboard. Kicad is an open source schematics capture and PCB layout software that can run in Windows, Linux and Mac. If you want to read the schematics or try it out, you can freely download it. In Ubuntu you could just use apt-get:

sudo apt-get install kicad fped

1	sudo apt-get install kicad fped

The hardware files for the module and carrier board are available here. JM explains that the LPC module and baseboard have already been manufactured and tested, so it could just be a matter of adapting the module for AllWinner A10/A20. […]
