Kernel - arch support(mips)

Kernel - arch support(mips)

[Domcan Sami]

Hi all,

I am trying to compile a program using a MIPS-LINUX cross compiler(gcc). I've set up a connection between my i386 Linux machine and a MIPS(RM7000) processor. This is again connected to a WinNT Terminal where there should be an output from the MIPS processor.

I have 2 kernels in my Linux machine under the directories:
1) /usr/src/linux - kernel version 2.2.14
2) /root/kernels/linux - kernel version 2.4.14

I am using a boot image generated from the older kernel for booting. The problem is the older kernel doesn't support MIPS architecture. What should I do to upgrade my kernel so that it supports MIPS architecture & that I'll be able to cross-compile my programs properly.

Please provide more information:

1.  What is your target platform -- e.g. make of model of the board or
    computer that has the RM7000 processor on/in it?

2.  Does the target support Linux, does it have a ROM monitor, or is it
    a raw embedded target (e.g. requires crt0)?

Searching on Google, it looks like you have a EV64120A-7000 made by
Galileo Technology, Inc..  It is a PCI card that plugs into a PC, and
includes the PMON ROM monitor in flash.  Galileo appears to have been
sold to Marvell (www.marvell.com).  I don't see support or search links
on the Marvell web site.  I don't see Galileo or EV64120A on their
product page.  I suggest you send them an e-mail asking if and what
support is available.


I was going to recommend the SDE-MIPS toolkit by Algorithmics, but I
don't see your board in their Programmer's Guide.  Try asking them if
they support it:

    http://www.algor-uk.com/


To be blunt, trying to make an older, slower, and unsupported board work
is going to be difficult.  It might not be possible.  If you can, get a
current, complete, and well-supported MIPS development system -- board,
ICE/JTAG, ROM monitor/ embedded OS, development toolchain, etc..
