Dockstar Pinout SDHC Card and I2C

@mindsmith

Did you look into the RTC?

[mindsmith]

yes here it is, you must connect the 32.768 kHz crystal, the two resistors you have to remove, because this are 0 Ohm to ground resistors. I realise the i forget the RCT Battery pins, i will measuring it today and update you.

Now here the new Picture for the RTC Pinout.
RTC_XOUT
RTC_XIN
RTC_AVSS (is connected to the system ground)
RTC_AVDD (Pin for the RTC Battery)

thanks mindsmith

Cool! Thanks!

No Problem, all information for free
But please share the information too, if somebody do something with it (I2S Audio, uBoot with SD-Card Support, or something else)
Thank you to all.

Nice to see progress with RTC !
A step by step guide on how to fix up clock would be nice

Had an error in one picture, here the right one. Sorry about it.
There was an writing error on MPP[16].

Hi All! I'm wondering how to enable the on-board S/PDIF audio output. Do I need to do more than solder 2 wires to the pins #37 and #38 or what? I read the Marvell documentation and it says those pins output minimum voltage is 2.4V. Wikipedia says that S/PDIF minimum input voltage is 0.2V. I don't want the magic smoke to escape from my AV equipment, nor the Dockstar.

Thank you if you can help me.

I'm not an expert in this matter, but a resistor divider might help. Are we sure it's really s/pdif and not something else like AES3? Anyway, this page might help identify a easy resistor circuit that could work, if it really is just a matter of voltage levels.
