Hi everybody !
I tried again to reach the promised 1.7GHz through this omap5.dtsi modification :
operating-points = < /* kHz uV */ 1000000 1060000 1500000 1250000 + 1700000 1290000 >;
Found those values here : https://github.com/omapconf/omapconf/blob/master/arch/arm/mach-omap/omap5/op...
I tested on both EVM and IGEP, 4.7.4 vanilla, and it now works (failed one year ago with IGEP's 3.8.x) : cpufreq stats: 1000 MHz:9.10%, 1.50 GHz:7.29%, 1.70 GHz:83.61%
$ time echo "scale=5000; a(1)*4" | bc -l @1.0 GHz : 1m26.008s @1.5 GHz : 0m56.667s @1.7 GHz : 0m50.420s
Under long make -j3 , the average temperature is only 2~4 °C more, but I have glued far better heatsinks on both my boards. No crash so far.
Thought this info may help here to expand ways of testing.
To add redundant information, I fuel the EVM with 12V and never encountered any crash @1.5GHz .
Cheers, LS
