Hi Jason: I am sorry that another problem appeared. After the /bin/sh ran, I can't see anything from console. I open the compile switch "SERIAL_DEBUG_INTR" in uart.c, then I can see the following message on console: THRE...rs_interrupt_single(0, 2)...end. THRE...rs_interrupt_single(0, 2)...end. . . . It means that the transmit interrupt is triggered, right? But why I can't see anything? And can you tell me that when shell outputs message to console, which function it uses in uart.c? I think it should be rs_8xx_write(), right? But I found that this function was not called before interrupt happened. Thanks! LiuTao
I'm glad to hear you resolved your problem. If I can lend you any other assistance, let me know, I have gone all the way through porting the kernel to a custom 860 board now and are familiar with solutions to some stumbling blocks.

I found the problem in uart.c, the BRG is setup incorrectly. I have resolved the problem. Now, I can see message from console port. Thanks. LiuTao
