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
