Is there any FreeRTOS port for the AT91SAM7X512 available ? I've successfully running AT91SAM7X256 with arm-elf-gcc (GCC) 4.2.1 and FreeRTOS 4.6.1 and want to use AT91SAM7X512 as well.
Best Regards. ozzy
RE: FreeRTOS support for AT91SAM7X512Posted by Dave on November 12, 2007 All you need to do when moving from a x256 to an x512 is change the linker script to be correct for the larger ROM/RAM sizes. You can use the same port.
RE: FreeRTOS support for AT91SAM7X512Posted by saiberion on November 12, 2007 There is no explicit port for the X512. But I think you can use the X256 code on an X512 nearly without any changes. The X512 differs to the X256 just in size of flash and ram, so adjust the ram size in the linker file properly to be sure.
As far as I know the chips of the SAM7 series are nearly identical. the biggest differences are between chips that have another letter before its number, e.g. the S-series only has one 32 PIO port wheres the X-series has 2 PIO ports and additional peripheral. Within a "lettered" series the chips differ in flash/rom/ram size.
RE: FreeRTOS support for AT91SAM7X512Posted by linux-ozzy on November 22, 2007 Hello ....
Thanx for the help. I successfully ported FreeRTOS for AT91SAM7X512. It is working very well. Maybe it could be possible to add a demo application for AT91SAM7X512 to FreeRTOS source in the next release.
Best Regards. ozzy

thanks in advance, saravanan

I'm still waiting for a reply to the question "which ARM926 processor are you using". Without that answer no more information than has already been given in other replies exists. It has already been stated that the two should be compatible, so it is down to what other changes need to be made. Without you giving information on which device you are using we can only guess. Atmel, ST, TI, FPGA, which?
RE: FreeRTOS support for AT91SAM7X512Posted by sara on November 30, 2007 Hello, Thanks for your quick reply.I am using freescale ARM926EJ-S processor.Where Can i modify the codes of STR91x(ARM966E-S) for my processor.If you having any further information ask me.
regards, saravanan
