I don't use DINK32. I use Codewarrior v.6.0 with BDI 2000. I'm trying to load the zImage.initrd on the SDRAM and directly run the kernel without using bootloader. I use MontaVista's hardhat linux. I configured the linux to work for Sandpoint. I use BDI2000 to initialize the bridge chip, which are less than 10 instructions long. After initialization, I can read/write sdram. And then I upload zImage.initrd at 0x800000. It successfully decompresses the kernel and jump to 0x00000000. >>From there it works fine until it enables MMU and jump to 0xC0000000. When it jumps to 0xC0000000, it only finds garbage there. All FFs at 0xC0000000. I checked the register MSR and BATs. They look OK. But address translation doesn't seem to occur. I think I need to do more initialization before I upload zImage.initrd and run it. Could anybody tell me what should i do? Thanks, Dong-In Kang ** Sent via the linuxppc-embedded mail list.
