Just a quick one. I built a system on my little atom box for 64 bit linux and ran it under qemu. Next, I think I'll get an Rpi and try building for that. Ken On 9/15/2012 4:52 PM, Kent A. Reed wrote: On 9/13/2012 12:03 PM, Kenneth Lerman wrote: I've just started looking at the yocto project

Point of view is everything. You said: the D5252 is almost a factor of 6 faster than the Rpi for this benchmark I would have said the Rpi is only a factor of 6 slower for this benchmark :-) It's also a factor of 20 smaller (a guess) and uses a factor of 20 less power (also a guess).

Michael, I took a quick look at the code and am wondering why there is a call to delay within the loop. The delay function is called with a value of n (default value is ten) which causes a loop incrementing a counter n times. What effect does the delay constant have on the timing? It's also

The last time I looked at HAL, it was limited to a very short command line. If it were possible to supply it with more information, we could build some truly generic HAL components. Four decades ago, when I worked at Bristol Division of ACCO (later Bristol Babcock), I built a HAL-like system.
