I would like to ask your help regarding this RTC problem on my new IBoard Pro made by Itead Studio.
Asking directly to them took months and still NO answer.
My problem is when RTC battery attached to the board, the time/RTC is error and it is not running.
This is what I’ve got on the serial window:
RTC is NOT running!
But when I remove the battery, the time is fine, update and incrementing (as long power connected to the board only).
I quote earlier post on Itead studio forum about removing 1M resistor near the x-tal clock.
" please connect 0R between the crystal and the 1M resistor, and remove the 1M resistor."
Since the X-tal has two 1M resistors on each leg and my board (version unknown?) have 0 R unconnected, Do you know what should I do to fix this bug??
Thank you for any help,
