booting a kernel over tftp - hibernick - 03-08-2018
Hi ,
I have configured u-boot on my rock64 to load boot scripts over tftp and it works well.
What I'm missing is a little understanding how to setup kernel boot over tftp.
I've got kernel image compiled using ayufan-rock64/linux-build repo.
It's there linux-build/kernel/arch/arm64/boot/Image
System.map shows that these addresses:
Quote:ffffff8008080000 t _head
ffffff8008080000 T _text
ffffff8008080800 T __exception_text_start
ffffff8008080800 T _stext
ffffff8008080800 T do_undefinstr
I'm not sure whether they are physical but u-boot doesn't use MMU
Can I use this kernel for booting over tftp or I have to use another configuration for this.
If yes then what load address and entry point should I use for mkinage:
Quote:mkimage -A arm64 -T kernel -O linux -C none -n 'Kernel Image' -a $load addres -e $entry point -d boot-image linux-build/kernel/arch/arm64/boot/Image
What memory layout does rock64 have?
To be more specific, what is RAM start address?
Does it matter where I load kernel image in u-boot:
Quote:tftpboot 0x02000000 or tftpboot 0x8000
Thanks a lot in advsnce
