[U-Boot-Users] PPCBoot vxworks question

[Timothy Canham]

I am new to the list and new to PPCBoot/UBoot, so apologies in advance 
if this is old territory. I am trying to load a vxworks kernel located 
on an external server, using the typical vxworks boot loader. i.e., the 
vxworks boot loader loads a kernel from a remote server using rsh and 
jumps to it. From what I can see, PPCBoot has the bootvx command, but it 
appears to require that the vxworks kernel already be loaded to work.

Can someone post the equivalent procedure to duplicate in PPCBoot what 
the vxworks boot loader does?

Well, I don't know what the VxWorks bootloader does, but I know
PPCBoot/U-Boot.  In order to get any of the boot[x] commands to
work, it assumes you have the kernel image loaded into memory
already.  For example, to load and execute the Linux kernel, here is
one method assuming you have a properly functioning Ethernet i/f and
a tftpserver.

tftpboot 400000 linux-ppcboot-image
bootm 400000

The first line loads the kernel image into memory at my chosen
address of 0x40_0000 and the second line transfers control to it.

The other thing you must do for this to work is to put the PPCBoot /
U-Boot header on your kernel image using the mkimage utility that
comes with U-Boot.  The README file in U-Boot distribution contains
this info and much more!
