Porting FreeRTOS on OpenRISCPosted by Hi-all on March 23, 2011 Dear all. Currently I'm porting FreeRTOS-6.1.0 on OpenRISC(or1200). I've already found source code designed by "mattzz" and "Tzu-Chien Chiu" But, as far as I know, they are not actually preemptive scheduling. Please let me know where can I find some example. Thanks in advance. Email: shyou@eyenix.com RE: Porting FreeRTOS on OpenRISCPosted by Ivan on March 23, 2011 Hi, I'm working with FreeRTOS 6.1.0 on a RX62N. I don't quite get what you mean by "not actually preemptive scheduling". From my code walks through FreeRTOS and my testing with interrupts thus far, FreeRTOS does have preemptive scheduling. Hope it helps :) Cheers! RE: Porting FreeRTOS on OpenRISCPosted by Hi-all on March 23, 2011 Hi. I mean, the source code designed by "mattzz" and "Tzu-Chien Chiu" does not support preemptive scheduling. They didn't yet apply context switching in interrupt service routine. So, I requested some other porting examples of the source code for FreeRTOS, on OpenRISC. Thanks. RE: Porting FreeRTOS on OpenRISCPosted by Richard on March 23, 2011 I am not familiar with the code you are referring to, or the OpenRISC architecture - but would say it would seem to make perfect sense to have FreeRTOS running on an OpenRISC and if somebody does have a port then please upload it to the FreeRTOS Interactive site. I can make a special OpenRISC forum there if necessary. Regards.
