First of all, thanks for Jan give me advice. I accept his advice and obtain some information. (NOTE: I just used the new project and I never changed the configs/arm64/rpi4.c) when I execute jailhouse enable rpi4.c the error is JAILHOUSE_ENABLE: Invalid argument and then I see some information from the putty jailhouse:request_mem_region failed for hypervisor memory I don't know whether this error caused or not. Because I can run successfully using old project and it also warn this problem. And I execute the followed command sudo jailhouse config check configs/arm64/rpi4.cell the message is: Reading configuration set: Root cell: Raspberry-Pi4 (configs/arm64/rpi4.cell) Overlapping memory regions inside cell: None Overlapping memory regions with hypervisor: None Missing PCI MMCONFIG interceptions: None Missing resource interceptions for architecture arm64: None So what should I do ? If I can get your generous help , I will appreciate. Yours, Hongpeng Cao. -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
