Hello,
Besides an RTX task polling, is there any glue that interconnects an FIQ with an RTX task?
Details below and thank you for your help, Lonnie
Details I have a peripheral driver (ARM Cortex) that is asynchronous and triggers an FIQ when it receives data. The FIQ analyzes the data (checks to see if it had received the correct closing sequence). Now, somehow I need to inform an RTX task that the complete set of data has been received.
Since FIQ cannot call RTX functions, how can I inform the task that there is data ready? I can only think of polling.
Unless, there is some way to mate an RTX software interrupt to the peripheral?
