TE0720 rtc mapping

Hello,

I'm having trouble to use the provided RTC on my TE0720-03-2IF module which I'm using on a custom carrier. I don't know how to reach the I2C bus to which the RTC is connected to from my bare metal application. And in Vivado I don't know to were I must map the IIC_1 peripheral to, to make the bus visible for the ARM. The next page:

https://wiki.trenz-electronic.de/display/TE0720/I2C+Peripherals

states that: 'It is recommended to map PS I2C1 via EMIO to this I2C bus.'

I activated the IIC_1 peripheral in the ZYNQ_processing_system in the (existing) block design but cannot figure out were to connect it to... Propably I'm missing out something very obviously.


Thanks in advance!

Hello,

you can use our reference design:

I2C1 to  RTC is connected over System Controller IP on external PL IOs.
