The BDI2000 for Codewarrior is connected to the JTAG port of the Sandpoint X3. I used the Codewarrior to load the linux kernel to the SDRAM of the Sandpoint X3. Of course, I used GCC to compile Montavista Linux kernel. (I heard that BDIgdb is the best tool for Linux kernel debugging. I'm considering purchasing BDIgdb. Currently, I have a problem of enabling mmu. After the initial boot part of the Linux finishes setting up BATs and enables the mmu, the address translation is not done properly. So, when the kernel jumps to 0xC0000000, it jumps to physical address 0xC0000000. It crashes there. I suspect BDI2000 with Codewarrior does not support mmu.

If you are, look in Documentation/kernel-parameters.txt for more info. Mark ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
