FreeRTOS port for ARM&EVA

Posted by vmo on January 9, 2008
Hi,

I am new in embedded programming. We want to put the FreeRTOS on this ARM&EVA board, which has an ARM9 based MCU module. At this point we couldn't find a detailed documentation on how to do that, i.e. the porting process and the installation. Any advice is welcomed.

Thanks,

Victoria

Did you see this page? http://www.freertos.org/FreeRTOS-porting-guide.html

There is not much difference between various ARM ports so it should not be a big problem.

Hi,

Thank for your answer. The time is an issue for us, so we would like to know how difficult and how much effort it will take a new FreeRTOS port for this specific platform.

Thanks,
Victoria

You can always ask for a quote for a port from the FreeRTOS site.

Hi again,

I have some additional info about the platform that we are using (ARM&EVA): it is an ARM9 based platform that has an AT91RM9200 32-bit RISC @ 200 MIPS. I am wondering if there is a port for this, or if there is a different one but which we can use as a start point (because starting from scratch is quite difficult..) and what are the first things that we should change there..

Thanks,

Victoria

Start with an AT91SAM7 demo they should be very similar. You will need to setup the linker script and configure the clocks and external bus interface. The port code should not need much if any changes.
