Hello,

We are using a custom board with device Xilinx Zynq 7030.

We are using Analog devices reference design for zc702 board available on analogdevicesinc github. 

We are trying to bring up the Linaro ubuntu Desktop form PS Side on the HDMI port connected to the PL side.

We first are trying to run the HDMI Transmitter via non-os code provided by analog devices.

 

When we run the no-os driver code of adv7511 transmitter then the code gets stuck in the HAl_PlatformInit() function.

I read on the community that this is because the vc707 and zc702 boards contained an i2c switch on the i2c bus and this may cause problems on custom hardwares that don't.

As there is no source for HAL_PlatformInit() function we are not able to debug as well.

 

Is there any workaround this issue?

We need to make HDMI work from non-os and from Linux as well. Please could you guide us in this matter.
