I'm having problems trying to recompile parts of the kernel/boot code to = allow me to single step through some broken code. It appears that the code in /boot/... seems to be compiled without = 'debug' info, other than the kernel. I need to debug the loader code, and am having difficulty rebuilding = only 'ubldr' and attendant common/library files. And of course, needless to say the board I'm working on is not a = currently supported/ported-to powerpc board. The freescale designator is: p1020wlan, and while it resembles a p1020rdb=85 it is sufficiently = different as to disallow that board's configurations to just 'work'=85 As a note note=85 it would seem that FreeBSD still has not really gone = 'embedded', since there doesn't seem to have an 'easy' mechanism for = just copying compressed kernel image out of rom, into ram, and jump to the = start entry point. There's also only vague references to what the kernel expects in the 'parameters' passed from the boot loader. Any help appreciated. John Clark.
