Hi Oak,

What sort of timer are you looking for? We do not currently have any drivers on or in seL4 for the I.MX6 that output real time, if by real time you mean wall clock time.

The real-time branch, which is tickless, has an in kernel driver for the 64 bit global timer [1] which counts time since boot and uses this to schedule periodic threads.

Thanks, let me know if I can be further help.
Anna.

Hi,

I was wondering if there's any real time clock implementation for I.MX6 in sel4.

And if there isnt any, what would be the best way to use a timer in sel4 (since I saw many implementations of those)?

through sel4platsupport_get_default_timer?

Best,

Oak
