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
