Hi,
I need to stream audio/video through Raspberry PI so I applied a/m chip. Initially it should work on my PCB made according to the datasheet. However at the very first start-up I have such observations :
1. current consumption from 1.8V is approx. 30mA
2. I2C port doesn't work at all (RPI commands say "no such device")
3. CSI lines (clock and data) stay at 0.2 - 0V level. No activity there.
4. Vrefp and Vrefn are 0V
5. Crystal works at expected frequency
So what to do next ? First samples were taken from Digi-Key.
Best regards
Jacek
