cpu speed

cpu speed

[AlessandroPPC]

Dear all,

I 've a MPC8260 board with 2.4.18 kernel version and nfs root fs . First I
have configurated it with cpu_clock = 133 MHz, cpm_clock = 100 MHz and
bus_clock = 33 Mhz with good results.
Then I have changed this configuration with cpu_clock = 166 MHz, cpm_clock =
100 MHz and bus_clock = 33 Mhz with bad results.
With cpu clock at 166 Mhz I have several error but typically "Illegal
istruction " error message is send on the console.
I have checked the bus timing (memory read/write access) with no difference
rispect to cpu_clock at 133 MHz.

Can be a cache problem ?

Tanks to all,
Alessandro.

I have strong doubts about tools like this - amazingly well though how
it may actually do the job in a certain setup. Building a monolithic
block of software first, and then rip it apart again just doesn't seem
right to me.

If you're really short on memory, you should consider using an
alternative library solution like uClibc.

Just my 2 cents.

Marius
