I have seen that lot of arm boards are having qnx rtos but all were like cortex-a or cortex-r ,but the soc i have is having cortex-m3 ,so before investing lot of time in this os ,i want to be sure whether at the end it will work with cortex-m3 or not , or should i give it a shot.
Hi sam1234,
It seems like there is no port of QNX Neutrino to Cortex-M(3). For ARM CPUs this RTOS works only on the application processors ARM720, ARM9, ARM11, ARM Cortex-As and the related CPUs StrongARM and XScale.
... should i give it a shot.
In my opinion it depends on your specific need. If QNX Neutrino is more important to you then you can opt for Cortex-A instead. You can use the Cortex-M3 that you have on other project. On the other hand, if it is more practical for you to use your existing Cortex-M3, you can try other RTOS which can run on Cortex-M3. Here are some: eCos, FreeRTOS, Nucleus, RTXC Quadros, ThreadX, μC/OS.
