ADM5120: linux-2.4.31-adm.diff.bz2 does not support PCI bus?

Hi,

I am now working on a board with ADM5120 processor and want a kernel newer than 2.4.18, so I tried the linux-2.4.31-adm.diff.bz2 patch against vanilla 2.4.31 (http://www.linux-mips.org/wiki/ADMtek#Linux_2.4) but failed to compile it with PCI Bus support (It compiles OK without CONFIG_PCI). The compile error looks like this:

......

Is PCI Bus supported by this patch? Or, is there any new kernel availible for ADM5120?

Thanks very much.

Hi,

2005/7/13, IHOLLO <[email protected]>:

Did you turn on New PCI bus code(CONFIG_PCI_NEW)?

Yoichi

Thanks Yoichi, that is exactly what you suggested, turn on New PCI bus code(CONFIG_PCI_NEW) then the kernel can be compiled now.

Here is another question: What CPU type should I choose to compile applications for ADM5120? the spec says it is MIPS32, but I can not run MIPS32 applications on my board while MIPS-I executable works just fine.

#file busybox (works fine. compiled as mips-I)
busybox: ELF 32-bit LSB MIPS-I executable, MIPS, version 1 (SYSV), dynamically linked (uses shared libs), stripped

#file busybox (can not execute this program. compiled as mips32)
busybox: ELF 32-bit LSB executable, MIPS, version 1 (SYSV), dynamically linked (uses shared libs), stripped
