mipi_csi2_rx_subsystem was not initialized!

[shantaramj]

Hello folks,

I am building Pcam-5c petalinux project. For this we are using zybo-Z7-20 and referring following github link:

https://github.com/Digilent/Zybo-Z7-20-base-linux

Software versions:

Vivado ver. 2018.2
petalinux ver. 2018.2

I am getting following error message in linux boot log.

Linux boot log :

Thanks in advance

Hi,

That project is only compatible with 2017.4. We're working on updating it to a newer version but it a complex process and we don't have an estimate yet.

Okay, Thanks.
