Thanks for your advice again! From my perspective, whether it was caused by Linux version or not. And I execute 1.git clone https://github.com/siemens/linux.git 2.git checkout -b jailhouse-enabling/5.4-rpi 3.git reset --hard 57e5db56e9c9511c4371c61065334a689af60a72 //I want to clone this version 4.make menuconfig 5.make && make modules_install && make install However it is failed and still not to enable rpi4.cell. My solutions is right or not. By the way, according to your advice, I need to alter the jailhouse.dts right? If I can get your generous help, I will appreciate !
