Hi Oak,
For an accurate timer at user level you can use the gpt driver here :
https://github.com/seL4/seL4_libs/blob/master/libsel4platsupport/src/mach/i…
Note that a while ago we combined a lot of our library repos, so libsel4platsupport is not
part of the larger seL4_libs. The stand alone version is no longer updated.
Cheers,
Anna.

Thanks Anna.
We are looking for a way to get timestamp (wall clock) that can be used in the userland
for authenticating an incoming message from remote server.
I see that the real-time clock driver is not implemented yet but an accurate timer would
do the job too.
So any recommendation on which timer implementation to use?
Would this one work?

Thanks,
Oak

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
