I have a Samsung vacuum cleaner, Navibot model 8845. The CPU oscillator pins show 1.4 V and 0.9 V. CPU supply voltage is 3.3 V. I have changed the ceramic resonator of 8 MHz still CPU clock is not working. Should I use quartz crystal instead of resonator?
I will appreciate help as the battery, charger, all the motors and sensors etc. are working.
thanks ,
regards,
