Hello,
Hi
I am having an embedded linux system and wanted to use any RTOS on it. Can I use Free RTOS? My project has 2 tasks , one is producer and another is consumer working parallely. I'm afraid I don't understand what you are requesting and I hope that someone else understand more clearly. But I'll still explain my understanding. You want to run a RTOS upon Linux OS, doesn't make it too much OSes? Then I have several questions: Do you really need a Real Time Operating System, can't you run your project in Linux userspace?
I can do that but Linux is not an ROS afaik. Even though i dont have strict timing requirements , its like a sensor on i2c(producer) and then another consumer tasks which not only feeds on this data but also tell the i2c sensor by sending some commands to it.
Have you tried Linux RTOS extension (again I'm no expert and haven't tried them but you can look at Xenomai)? I will explore this.I was thinking if i can use Posix thread to have two tasks one reading sensors and another sending commands to it.But then again i am confused if using a posix thread full fills the requirement of RTOS. The reason I want to use RTOS is , I am porting a Microcontroller code using RTOS (free RTOS) to Linux and afaik FreeRTOS doesnt work on Linux. FreeRTOS is a standalone OS and depending on your system there may be an example running on your architecture in parallel of your embedded Linux. For example, on one of my project with have an ARM Cortex-A7 with Linux running in Normal World and FreeRTOS running in Trusted world. This is interesting , do you have something to share?
I have seen Free RTOS used in microcontrollers handling this , how can this be done in Linux(which such APIs if not Free RTOS).
HTH
