Is this really right?
What is the reason?
Unification. Otherwise every device would have its own boot flow.
Must i really use grub2 with efi?
Yes.
Why not selected in Bootloader like in x68 at startup?
I have done this under lxqt.
I have select grub2 with efi.
And after reboot the screen is black and no chance to login.
That sounds like a bug, you should report it.
yes it is a bug.
I'm a step forward.
First failure/bug is that "grub2 with efi" is not selected when start
yast bootloader.
Second failure/bug is, that when switch to "grub2 with efi" all kernel
paramters for raspi are gone.
Before: loglevel=3 splash=silent plymouth.enable=0 swiotlb=512 cma=300M
console=ttyS1,115200n8 console=tty root=UUID=xxxxxxxxxxxxxxxxxx rw
After: splash=silent quiet showopts
When i insert swiotlb=512 cma=300M console=ttyS1,115200n8 console=tty rw
to kernel parameter at boot time i came up.
But what is plymouth.enable=0?
What is swiotlb=512?
What is cma=300M?
Need i really console=ttyS1,115200n8 console=tty?
Need i rw?
