Hello everyone,
I have an initramfs file that want to be called via initrd in Barebox.
I have configured my boot script as below:
#!/bin/sh
global.bootm.image="/mnt/mmc1.0/Image"
global.bootm.initrd="/mnt/mmc1.0/initramfs"
global.bootm.oftree="/mnt/mmc1.0/Image-fsl-imx8mm-evk.dtb"
global.linux.bootargs.dyn.root="root=/dev/mmcblk1p5 rootwait video=-32
fsck.repair=yes"
But when I call this boot script, initramfs is not executed and only Linux
Kernel and device tree are loaded and system boots.
I have done this process on imx6 board previously and my initramfs was called
successfully via initrd.
Is this feature not available for imx8mq/imx8mm? Actually the function
bootm_load_initrd is never called.
Best regards,
Reyhaneh

[Sidenote: bootm.verbose shows some extra boot info]
The bootm handler code for arm64 is in arch/arm/lib64/armlinux.c
There's no loading of an initrd there, unlike arch/arm/lib32/bootm.c
so I'd assume it's indeed not implemented, but I don't think it's difficult
to add though, maybe you want to write a patch? :)
Otherwise, you could always have the initramfs embedded in the kernel image.
Cheers
Ahmad

Hi Ahmad,
yes, you are right. We can embed initramfs in Kernel. I will try to implement
initrd for lib64 in Barebox. Then, I will post it here as a patch :)
