Sorry Ralf, I did an error with the dtb. It works with the inmate-zynqmp-zcu102.dtb. However, I do not achieve to see the non-root linux console. I have tried with ttyS0 and ttyS1, but nothing appears. How can I access to the second cell? -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
