Hello laurent: You propose to me: "Try to upgrade to a recent kernel. 2.6.14 is more than 5 years old."
It isn't possible to use a newer/newest kernel. I tried to compile different versions of kernels (2.6.18, 2.6.20, 2.6.22, 2.6.24....2.6.38 ) and basically is impossible for some reasons: 1) the toolchains is very old (3.3.2 version). I wrote to ARTILA's support tech asking about a new toolchain because I need to compile a newer kernel and your answers was: "this is the last toolchains for your board, you must to use this". I download different versions of ARM's toolchains (like code sourcery lite version http://www.codesourcery.com/sgpp/lite/arm and others more), if I well I can to compile a c or c++ file, when I try to compile or I upload to my target the the executable, isn't working. 2) Russell King ( he supports the ARM Linux kernel community http://www.arm.linux.org.uk ) on your site wrote this: <<Downloading an ARM patch: You only need this step if you are using a kernel prior to 2.6.0-test2. There are no -rmk or -vrs patches for later kernels.>> I suppose that recent versions of kernel has support for ARM architecture, but, when I tried to compile different versions of kernels, always I obtain different errors. 3) On ARTILA ftp site, the "last kernel version" is 2.6.14-M5 kernel version update to september 15 / 2010, I think. (for me it's a bad joke to say "last kernel version" to a 2.6.14 version). I read something about URB and I don't know what I must to be for to solve this error. If you have some idea about how to proceeded I will appreciate very much.
