booting on embedded planet RPX_LITE-DW (823e)
Hello,
I'm using the ELDK from www.denx.de/ELDK for the ppc_8xx target -- it was very easy to
download and setup !
I'm trying to build the 2.4.4 kernel that comes with ELDK (..eldk/ppc_8xx/usr/src/linux).
My board is a RPX_LITE-DW (w/ a 823e PPC) from embedded planet.
I have a couple of questions regarding:
* building a kernel with a ramdisk image
* loading a kernel image via tftp on the RPX_LITE
_Building a ramdisk image:
I know how to build the ramdisk image, however, I do not know how to tell the kernel to
use the ram disk image. How is this done? Do I copy the image to
usr/src/linux/arch/ppc/boot/images or to mbxboot ? Do I use "make zImage.initrd" ? Any
other gotchas ?
_Loading a kernel image:
I believe I have the tftp setup correctly. I downloading the image and jumping to its
start like this:
>> t
>> Load using tftp via Ethernet
>> Enter server IP address <10.0.0.1> :
>>
>> Enter server filename <ppc-zImage> :
>>
>> Enter (B)inary or (S)record input mode <S> : B
>> B
>> Enter address offset : <FFF80000 hex> : 180000
>> 180000
>> .512.1024..2048....4096
>> Total bytes = 2270744 in 3565728 uSecs
>> Loaded addresses 00180000 through 003AA617.
>> Start address = 00180000
>> >g
>> g
>> [Go 00180000]
Is that a good starting address? How do I know what the starting address should be?
Needless to say my serial connection hangs after the "Go 00180000" command, so I do not
know what is happening.
Any help would be greating appreciated.
Cheers,
Curt
