Hello, I am trying to run Linux on a EST's SBC8260 board.
First thing I have tried is using ppcboot to load the Linux kernel image. - ppcboot version is 1.1.6 - Linux version is 2.4.4 - the one that comes with ELDK from Wolfgang. (as a side question - is it enough if I do the 'make est8260_config' or I need to do menuconfig as well after that?) First I have used the Linux kernel image, one in arch/ppc/coffboot and converted using mkimage tool (with parameters -a 0x0000_0000 and -e 0x0000_0000) ppcboot is running on my board and I have loaded linux image (the converted one). After that I have executed ppcboot 'bootm' command, and got the message 'Loading Kernel Image OK' -- (?? this is strange though - should it not say here Uncompressing Kernel Image ?) After that nothing happens on my serial console. So I tried to use the BDI2000 to debug this. I skipped the ppcboot, and loaded the Linux Kernel Image (now the one from arch/ppc/mbxboot) into the RAM directly. After setting the PC and doing a 'go' I got the message that the 'Target has entered debug state' with 'Debug Entry cause (reserved 0)' I am not sure how much this helps, but by doing a 'objdump' on the image file and comparing the last PC after the 'go' command, it seems to be stuck somewhere is 'serial_init' section. BTW, I also tried compiling the Linux Kernel with '-g -ggdb' option. Should not the image size in case I compile with and without this options differ, because when I compare images in these two cases they are the same. I wanted to use this for gdb debugging. What am I doing wrong in this process(es)? Regards and thanks Dejan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
