And I'm encountering a few problems.=20 1. When I directly download zImage.elf to the RAM and boot from there, I = see the kernel starts booting, but it complains about not being able to = mount /dev/sysace/disc0/part2 and thus kernel panic happens.

When I tried to boot the zImage (sitting in the flash) from u-boot = file (generated from the same source code as uImage.elf), as soon as it gives = the control to the kernel, no messages would come. I checked to make sure = that I had the right serial port setting (console=3DttyS0,9600), but still = nothing shows up. Here's the output of what I had (I turned on some extra debug msg in = u-boot) ------------------------------------------- ### No HW ID - assuming ML403 DRAM: 64 MB FLASH: 8 MB In: serial Out: serial Err: serial Hit any key to stop autoboot: 5 =08=08=08 4 =08=08=08 3 =08=08=08 2 = =08=08=08 0=20 =3D> bootm 0xffa00000 ## Booting image at ffa00000 ...

Lastly, whenever I issue a reset command in u-boot, it just locks up = and hangs. I have to do a hardware reset every time. I'm wondering if the = reset vector is going to a wrong place. How would I check that? I'm fairly new to the whole embedded domain. Please feel free to help. = It would be much appreciated! Thanks. Aleck
