BB xM rev c ethernet

zamek_z · August 15, 2011, 6:34pm

Hi All,

I have a BB xM rev c and I want to compile a new kernel, because I need
S-video.
I use buildroot to build system. S-video is working well, but ethernet
cannot. I checked a working Ubuntu distrib which modules is loaded?
( Unfortunately all my checked working kernel didn’t contains
/proc/config.gz, so I couldn’t get a good .config for kernel compile. )

I found only 4 modules:

smsc95xx
rtc_twl
twl_4030_madc_hwmon
gpio_keys

I found 3 config settings (I couldn’t found gpio_keys , but I think so
it isn’t relevant) in kernel config, but when I compiled it, ethernet
couldn’t works

My question is that: what magic is in ethernet config in BB xM rev C?
What modules do I need to use for Ethernet?

Well you should at-least post your current .config...

Double check that these are enabled... (smsc95xx is on the ehci port)

CONFIG_USB_ARCH_HAS_EHCI=y
CONFIG_USB_EHCI_HCD=y
CONFIG_USB_EHCI_TT_NEWSCHED=y
CONFIG_USB_EHCI_HCD_OMAP=y

Yes, all of them is set to y.
here is my .config:

Nothing obvious, the .config looks fine when compared to mine..

Any chance are you using a gcc-4.6 based arm cross compiler?

No, I am using gcc 4.5. I can select
gcc4.2
gcc4.3
gcc4.4
gcc4.5
gcc4.6
or gcc snapshot

Buildroot can use external toolchain (codesourcery). I switched to it, but its result is very buggy, I cannot login as root
