Thanks Alex,
That makes some sense :)
I will try the u-boot.bin with qemu and will try to load haiku_loader than..
I think we need to debug how to emulate all the blob with in one mmc image
in qemu-system-arm. That should be first Step/Task.

Hi All,
I am trying to run haiku over Raspberry Pi. I builded the image
for
haiku-rpi1.mmc and tried running over Qemu. but got crashed.
I tried :
_qemu-system-arm -drive if=sd ./haiku-rpi1.mmc -machine
realview-eb-mpcore -cpu arm1176 _
it resulted :
qemu: fatal: Trying to execute code outside RAM or ROM at

Looks like the address which it is trying to load is invalid. Or
the
command parameters are wrong. Well with latest QEMU we also have
machine as raspi2, I have builded it and will use tommorow.
But i am looking forward for some suggestions/understanding/Ideas,
I
would like to contribute in its development.
We never got much progress under qemu. (there wasn't anything even
remotely
close to the Raspberry Pi target CPU when we started dev)
This just gives a blank screen + no serial output under a later qemu
version:
qemu-system-arm -drive if=sd,file=haiku-rpi2.mmc,format=raw -machine
raspi2 -serial stdio -m 2048
I will try this command.
You might want to try giving it a known working u-boot image, then
trying to load our haiku_loader.ub from the mmc.
Can you elaborate this more.? Do you mean i must boot some other
non-haiku uboot over qemu, and then load our?
How can i get haiku_loader.ub from builded mmc? ?
The haiku_loader packaged for u-boot is within the mmc image
(which is pretty much a hard disk image with a partition table)
We actually package the u-boot inside the mmc image as well.
The pre-compiled u-boot binaries come from here:
https://github.com/haiku/firmware
The problem is while qemu-system-arm emulates a raspberry pi 2, it doesn't
emulate all the system firmware blobs that are part of the soc. So you
have to
manually fire up the u-boot code, then start the haiku_loader which has
already
been wrapped to launch from u-boot.
