Can also say that the chip os 4.4 has some obvious faults, has played with the unit some days now. And find two faults. One when i flashed the unit, that the apt database file be corrupt with just zeros. Have not find why.. but when i flashed the unit some more times with the same image file, the fault disappear. And when you tries to change the uboot settings for the display settings to change from ntsc to pal, the settings will be overwritten then it boots.
Have not get the hole picture how the chip work.
Lets do some more investigation, but i hope that it's more funny, than doing the error correction for the NTC.
