Hi, I'm using uClinux with kernel 2.4.32 and compiler 4.11-30 from Codesourcery on a M5208EVB. I compiled dhrystone using the following CFLAGS : CFLAGS="-O2 -Wa,-memac -Wa,-mcpu=5208 -mcpu=5208 -DNO_PROTOTYPES=1" (I also tried with much more complete CFLAGS).
I ran dhrystone on this board and got this poor result : Microseconds for one run through Dhrystone: 40.1 Dhrystones per Second: 24937.7 which means 14 DMIPS (the CPU runs at 166MHz and is expected - by the shortform - to give up to 159 DMIPS). I understand the OS eats a few DMIPS but I don't understand why I only get 1/10th of the expected CPU power of this CPU. Do you have any idea of what could be wrong ?
