Simple free rtos app

Posted by ghostrider on July 12, 2012

Could any one please show me a link for a simple application using free rtos that can run on EVK1100 using AVR Studio 5.1. I have used the ASF application provided by AVR studio but it doesnt seem to work on h/w. Would be highly appreicable if anyone could guide me.

Thanks in Advance.

I have downloaded AvrStudio 6 (Latest version) and tried to use the toolchain to build the Freertos (V7.1.1). I am getting the following compilation error when built for GCC (EVK1100). I'm really kind of doubtful if the FreeRtos has ever been ported for AVR32 EVK1100.

c:\FreeRTOSV7.1.1\Demo\AVR32_UC3\AT32UC3A\GCC > make

avr32-gcc (AVR_32_bit_GNU_Toolchain_3.4.0_332) 4.4.3

There is a known issue listed for the AVR32 ports (http://www.freertos.org/a00104.html?1#knownissues), which will be updated soon. For now, please use the Atmel Studio distribution, which you can find with Atmel Studio 6, or http://asf.atmel.com
