RE: [Ltib] Can't get: linux-2.6.16-mx31-sdio.patch at./ltibline599.

[Sesto, Vin]

Hi Steve

I noticed on http://www.bitshrine.org/gpp/

There exists an rpm named

tc-fsl-x86lnx-armeabi-nptl-4.1.1-3.i386.rpm

Does this contain the crosstool and would this allow me to do what I
need to do? I am not having any luck.

Thanks.

Vin

Hi Vin,

The best place to look for patches is the crosstool project...

Without actually doing the modifications it's difficult to give exact
details of the changes that would be needed, and I'm pretty overloaded
at the moment... :-(

Best regards,

Steve
