Re: Uploading problem in OSK5912

[Jose Manuel Cano Garcia <jcgarcia@uma.es>]

Hi,

In the howto from oskfordummies a 2.6 kernel is recommended. Anyway, I 
supose you just have to recompile the kernel with jffs2 filesystem 
support and reflash it to the osk 5912 board.

Nevertheless...why are you reflashing the board if you are using the 
original montavista preview kit? Why not just download a .tar file with 
your application to the board original filesystem?
