New page

It is very simple to overclock your explorer

Lets say you want to boost the speed up to 532.5mhz?

cd /usr
vi speed

now type the fallowing in the new file ( press i to insert)

532500000

now press the Escape key and type :x

to speed up your system it is as easy as typing the fallowing

cat /usr/speed > /sys/devices/platform/lf1000-gpio/cpu_freq_in_hz

enjoy

-Once you have tested your overclock, and are sure that it is stable, and you haven't made any typos...
-You can actually get the startup script to automagically set the cpu freq for you!

 It is important that you test your chosen cpu frequency first using the procedure in section 1, or you might be left with an unbootable device.

 Now just reboot, and your Leapster Explorer will automatically boot at the faster speed.  Again, '''this is dangerous''', so test it first with the above method. I cannot stress this enough.

 At 164MHz the display went blank, and serial port stopped responding.
 At 600MHz a kernel panic occurred.
