No console output after switching from earlycon to ttyPS0

Hi

 

I use a Microzed-Board with a Zynq 7Z020. I created a new PetaLinux project based on the Microzed BSP from Avnet.

Then I added the hardware description file from Vivado and builded that project. When I boot that on the Microzed the console output stops after switching the console from earlycon to ttyPS0.

 

I already checked the DeviceTree properties of the UART1 and doesn't found any error. (UART1 is used for console output on Microzed)

Does anybody have an idea where the problem could be?

 

Used Tools:

- Vivado 2017.4

- PetaLinux 2017.4

Hi

 

May be you can try including the device tree bindings header for the PHY in the system-user.dtsi.

rHi

 

Thanks for the reply.

I could fix the problem meanwhile. The reason was a not clocked GPIO-Block in the PL. The XGpio-Driver could not communicate with the logic and blocked the boot process.

 

Kind regards 

 

Stefan
