Hi All,

I'm working on a stripped-down mpc8541 board (that has just a serian and twe enets). I have an issue on delay calibration. In fact at boot time, I see the following linux printk message on the serial console:

.... Calibrating delay loop... 83.20 BogoMIPS (lpj=166400) ....

The value seems reasonable. What freq is the core running at (guessing 833Mhz). My 1.5Ghz 8572 has a bogomips of 150.

Seems that the value is about a tenth of the core frequency. I observed similar on TQM8548. Although I know, that the value is bogus (as the name tells), do you know the reason, why it isn't the core frequency?

Thanks.

Kind regards, Jens

Thanks for the information... this means less work form me... at least for this day.

ciao

luigi

Please read the FAQ:
