Re: [Gumstix-users] Modules for USB webcam on verdex

[nptlnik <ni...@ne...>]

Hello,
 I am attempting to do the same thing with OpenEmbedded in bitbake, is there
any information that would help compile the files from there?  I am also
using a custom kernel to boot from the mmc (uSD) card.

Cheers,
Nikolaus
