HZ value in embedded Linux

HI,
How can i find the value of HZ in a working embedded ARM Linux from busy box? is there a command for that?
thanks in advance

Hi,
The HZ value, has, as far as I know, nothing to deal with busybox, since it's a kernel parameter. What you can do is to get the kernel config file if your kernel export it, if so you have it into the /proc/config.gz file or you can use the "extract-ikconfig" script. Else, maybe you have a /proc file with this information, I don't know but I think that google + proc + timer frequeny will answer.

Hi, and thanks.
actually what i meant with BusyBox, is using the shell commands to find out the values of HZ, that already is used by the running linux.
bcoz i know how to find the HZ value in kernel source or during configuration(e.g. make menuconfig).
more over i did not manage to find the "/proc/config.gz"
any help?

to get the value of HZ for a running linux, write a module that read HZ value.
just

include asm/param.h

unsigned int myHZ;
myHZ=HZ;
printk("System's HZ = %d",myHZ)


cheers
