I'm trying to launch Weston 10.0.3 on my RISCV development platform which does have a support for GPU and provides a pre-build SDK for launching Weston. Upon Launching Weston i'm noticing errors as below and unable to proceed further, and noticed error as "Error: cannot enable output 'DSI-1' without heads", although i'm not exactly sure if that's the main reason for this issue, But any suggestions are welcome.
