AM3517 uptime issue (goes forward 2^17 seconds)

Other Parts Discussed in Thread: TPS65023

Hi All,

We are using TI PSP 03.00.01.06 (Kernel 2.6.32) on Variscite board SOM-AM35.  The uptime (and also the system clock with date command) goes forward of exactly of 2^17 seconds without any user interaction/application. We normally notice this time warp after 2 days since when the terminal is on. RTC continues to be ok.

We also discovered that when we issue the command   "cat /proc/timer_list",  at the end of the list the value of  max_delta_ns  is exactly our time warp in seconds

max_delta_ns: 131072454787401

 

Furthermore, we noticed that in comparison to other arm architerctures (PXA) in the source code clockevents.c (kernel/time/) the function clockevent_delta2ns uses the value

KTIME_MAX instead of LONG_MAX.

Do you know if is there anyone else who noticed the same problem ?

Thank you in advance. I look forward to hearing from you.

Kind regards,

Paolo.
