Then I generated the BSP for linux 2.6. I found that there are some differences from the older version, e.g. there are some files such as XMakefile, xps_connected.cud, etc. I am confused with this. So could you please give me a hand on how to use such a generated BSP to build my linux 2.6 kernel? I cannot find any guidance on how to do that. Thanks for your help.
