So with the following command the booting should appear? jailhouse cell linux zynqmp-zcu102-linux-demo.cell Image -d inmate-zynqmp-zcu102.dtb -i rootfs.cpio -c "console=ttyPS1,115200" "jailhouse cell list" shows the non root cell running, but tsecond serial line port does not show anything. -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
