hello and sorry for the delay to report back. It seems that in arm architecture there are no frequency option it takes them from the architecture, from what I've read it is 100Hz with no option to change that. So what I did was simply uncheck the tickless kernel option. @vincele that's what I thought too but it seems this is not the case. @goldfish_paris the new patch for RT doesn't succeed for some reason so I'm stuck to .108 which is not a great problem for me. I do not have the expertise to try to fix it so whenever someone comes with a solution it will be most welcome, but so far it is n't urgent for me. Thanx again for all the info.

Thank you very much I will test tomorrow and report back!

Thank you for your reply. I have the build enviroment set up, I did not know about the RT patch for latest kernel. I 'll look in to that and let you know what happens. The thing is that in kernel menuconfig which is invoked by the build script there is no option to set up tick frequency. There is just one option to setup tickless kernel or not (I 'm wondering what will happen if unchecked since no tick frequency options are available). From a little diging around in varius .config files I could find there are no CONFIG_HZ=100 or 250 or 500 or 1000 lines neither CONFIG_HZ_100=y or n or not set. I tried to set this up in linux_sunxi/.config but it seems it get overwriten by the script. Could you point me to the proper .config or .config template being used by armbian? Thank you

Hello Everybody I'm using olimex olinuxino lime2. I'm to expiriment on real time linux. I could build the kernel with the real time patch by disabling newer kernel patches, .108 and on, but I would really like to have a ticking system. There are not options for this in the kernel menu configuration. Just tickless system. That may cause some extra delays on realtime processes. Is there a way to configure tick frequency at 1khz? Thank you for your time
