FreeRTOS and AT91SAM7A3

Posted by Nobody/Anonymous on November 18, 2005
Dear freeRTOS users,

I would like to port freeRTOS for AT91SAM7A3 for IAR Workbench. I start from the AT91SAM7S64 version, now I have the com0 working and so the IO leds are flashing. Usb doesn't work I'm trying to understand what I have to change...Does anybody have any suggestions as starting point?

Are the register locations identical between the two sam7 chips? Maybe you have to use a different include file?

The AT91SAM7A3-EK uses a combination ESD protection and pullup in one small package. This needs, if I remember correctly, to be enabled by pulling one pin high.

I had to modify the USB startup code to do this. My board uses the same device, but isn't one of the eval kits so it'll have a different setup.

Hope this helps
