Re: your mail (yosemite + 2.6.x issues)

Do you load the kernel first and then do a "go"? If you load the kernel first using the "load" command, then you should come back to the PMON prompt where you can type a "go". I was not clear about it from your email below.

Thanks

Thanks Ralf, now I can compile the kernel.  But, I don't get any serial
console output when I try to boot it.  Actually, I get a single line that
looks like this:

Loading file: tftp://192.168.2.39/vmlinux (elf)
0x80100000/2288188 + 0x8032ea3c/111372(z) + 4125 syms|

I have found PMC's "yosemite_defconfig" file and I am using it as the
".config". I have tried using CONFIG_PMC_INTERNAL_UART=y and I have also
tried commenting it out.  Either way, I get no console output.

Thanks for the help!
Bryan

I would like to use a 2.6.x kernel with my Yosemite/HalfDome board.
Somehow, I am unable to compile the kernel. I have tried the 2.6.10


kernel


trees from ftp.pmc-sierra.com and also the latest 2.6.12 snapshot from
linux-mips.  I am using the 3.3.x cross compile tools from
ftp.pmc-sierra.com .  The 2.4.x kernels from PMC compile fine.

In the case of 2.6.10 from ftp.pmc-sierra.com, my error looks like:
Make[3]: *** [drivers/char/agp/backend.o] Error 1



Configuring AGP support for a MIPS kernel is obviously nonsense. Disable CONFIG_AGP.



In the case of 2.6.12 from linux-mips, my error looks like:
drivers/net/titan_ge.c1950: error: 'titan_device_remove" undeclared
here (not in a function)



Whoops, a bug. The function indeed doesn't exist even though it should, will fix that. You will hit this bug only if compiling the titan driver as a module, so workaround set CONFIG_TITAN_GE=y. Which for the typical titan-based device seems to be the preferable choice anyway.
