Uh, I copy the above note to this thread to continue:-) The turth is that I ported denx 2.4.24 successfully on my board and try to port it to 2.6.x. To my understanding, UART init was bad for some reason. It was auto configured as 16450 rather than 16550A as 2.4. Besides, ttyS0 iomem base address in 2.6 is different to the one in 2.4 although they have the same serial address setting. I wander which kind of possiblity coud lead to this result or even better to point out some useful printk locations to me. If possible, could you pls show me a right 2.6 boot process of sandpoint X3/2? I wanna to find out some nice hints of it. This is the first time to me so hard to debug a kernel before normal console. Thanks a lot, Sam _________________________________________________________ Do You Yahoo!? 150??MP3???????????? http://music.yisou.com/ ??????????????????? http://image.yisou.com 1G??1000??????????? http://cn.rd.yahoo.com/mail_cn/tag/1g/*http://cn.mail.yahoo.com/event/mail_1g/
