Hi dears
I have the same problem. When I do a "shutdown -h now", the RTC hwclock becomes corrupted. If I unplug/plug the power adapter directly It keep the time.
I tried a RPI2 and a RPI3 with the last Jessie update and upgrade and fake hwclock removed and two diferents RTC
Best regards.

How to read I2S audio input
Hi
I plan to connect an ADC to RPI through the I2S port. I need to read the audio input from I2S to do a audio capture.
I have the Raspberry PI 2 B with Raspbian Jessie.
What steps I have to do to read the digital audio from the I2S port.
Thanks in advance.
