Fix thermal issues

Just registered to say thank you for this. My orange pi was freezing up after few GB of sftp transfers - nothing but toggling power would make it responsive.
I was linked the sunxi page and tried it out. Now it works perfectly and stays at 59-60 at max.

Hi all,

Could anybody help me with this error?

orange@OrangePI:/tmp/cpuburn-arm$ ./cpufreq-ljt-stress-test
The cjpeg and djpeg tools from libjpeg-turbo are not found.
Trying to download and compile them.
CPU stress test, which is doing JPEG decoding by libjpeg-turbo
at different cpufreq operating points.

Hi bronco,

First of all, thank you for your script.
It ran sucessfully and the change was effective as expected.

Before script:
orange@OrangePI:~$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq
1536000
1536000
1536000
1536000

After script and reboot:
orange@OrangePI:~$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq
1200000
1200000
1200000
1200000
But, based in your script I was thinking that the result of my last command should be 1296000 instead of 1200000
;extremity_freq = 1296000000\max_freq = 1296000000\
min_freq = 648000000\
LV_count = 8\
LV1_freq = 1296000000\
LV1_volt = 1340\
