Dear Allan Wang, In message 880531.39933...@web52905.mail.re2.yahoo.com you wrote: Thank you for your help. My answer to your questions are between the lines. Attached is the dts file I use. No, there is no attachment. Which exact version of U-Boot are you running on this board? = version U-Boot 1.1.6 (Oct 25 2009 - 13:26:41) Um... why don't you update? This is really historic stuff... What is your exact boot command? I tftp the cuImage to address 0x20 and bootm to boot. Which boot arguments do you pass to the kernel? bootargs=$(bootargs) console=ttyS0,$(baudrate) Please provide complete answers, and not only the snippets that seem important to you. For example, what is the $(bootargs) above? Maybe you provide a full boot log right from reset/power on, including the output of the printenv command on your system. The u-boot sets it to 115.2k. the dts file is set to 115.2k. Here is the bo ot parameter: baudrate=115200 Arghhh.. Please provide the actual output fdrom your system, not just some parts you copy. What does your device tree look like? I attached my dts file. No, it's missing. 2. It pakics when mounting the root file system(NFS): (gdb) bt #0 panic (fmt=0xc0290e94 VFS: Unable to mount root fs on %s) So what is the %s argument here? Which sort of root file system are you trying to mount - NFS, ramdisk, UBIFS, ... ? I try to use NFS for the root file system. Then you can also run a packet sniffer (like wireshark) to see if any NFS requests actually get sent to the targte, resp. where it stops).

EP440XS board boot problem(Note:similart to Sequoia)
I resend my message since my last message has wrong coding. I am new to the list. I am still newbie to embedded linux. I have bought an ep440xs board which is similar to sequoia board. u-boot is working. I am trying to make it run linux. I have the following problems and need your help. Thank you very much: I am using linux kernel 2.6.30.4. I encounter 2 problems: 1. After console_init() is called inside start_kernel(), the console starts printing garbage like: Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled serial8250.0: ttyS0 at MMIO 0x1ef600300 (irq = 16) is a 16550A �� � �� �. 2. It pakics when mounting the root file system(NFS): (gdb) bt #0 panic (fmt=0xc0290e94 VFS: Unable to mount root fs on %s) at kernel/panic.c:70 #1 0xc02d8ce0 in mount_block_root (name=0xc0290de4 /dev/root, flags=0x8001) at init/do_mounts.c:272 #2 0xc02d9084 in prepare_namespace () at init/do_mounts.c:415 #3 0xc02d81ec in kernel_init (unused=value optimized out) at init/main.c:885 #4 0xc000de60 in kernel_thread () There is a patch for Sequoia board to delete /chosen part in sequoia.dts, is /chosen required?
