Re: [seL4] Get real time clock data (and timer) from I.MX6

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 The stand alone version is no longer updated.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. On 29/06/2016 1:39 pm, Norrathep Rattanavipanon wrote: 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? https://github.com/seL4/libsel4platsupport/blob/master/src/mach/imx/timer.c Thanks, Oak On Tue, Jun 28, 2016 at 5:17 PM, Norrathep Rattanavipanon <<mailto:nrattana@uci.edu>nrattana@uci.edu<mailto:nrattana@uci.edu>> wrote: 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?
