Hello everyone, I am a beginner VxWorks, has just started, recently met some problems when using auxiliary clock, want to ask next everybody, wish you glad,
I know X86 auxiliary power to the power of the clock must be set to 2, the default maximum is 8192, looked up some information, in the config in the BSP folder. The modified the maximum is 16384 h, at the same time in the system engineering of Tornado2.2 configuration also added auxiliary clock system, and will also assist in project file configuration of Tornado2.2 clock change the maximum values of macros to 16384, but after running the program, sysauxclkrateset (16384) returns false, and then I will modify the maximum of 8192, to run the program again, sysauxclkrateset (8192), return true, the program is running normal, want to ask next everybody, what's the problem, how to solve? Thank you for your attention!

Hello, may I have your problem solved? I had a problem when adjust the auxiliary clock frequency, could you share some of the specific steps? thank you

Clock Settings and vibration, under VxWorks sysauxclkrateset (value), the value value not appropriate is too large, the larger the value, from hard to soft real-time system,

Don't understand why you want to set up such a high frequency, want to set high value, change the crystals, in before consider x86 CPU support does not support such a high frequency,
