Hello, all I built linux 5.4.0 and made initramfs using busybox. I added the initramfs inside the linux kernel. The init file in the intramfs executes shell. After kernel boots on a arm64 virtual machine, I'm in the busybox shell. Now after I get file from outside world(using tftp), I cannot run the executable except the commands provided by the busybox. I guess there should be some people doing this all the time in this email list. How can I execute an executable file inside busybox? Of course the executable was compiled using proper cross-compiler. (it's arm64 virtual machine and I can run the executable on ubuntu-20.04 on the virtual machine. The difference is that now I'm trying to run it on vanilla 5.4.0 on the virtual machine) Thank you and any comment/advice will be welcomed.
