[U-Boot-Users] When starting linux, nothing happens

[U-Boot-Users] When starting linux, nothing happens

[jescythe]

i don't know if the problem is with my configuration of u-boot or the
linux image.

# bootm bfc80000
## Booting image at bfc80000 ...
   Image Name:   linux kernel image
   Created:      2005-11-03   9:22:24 UTC
   Image Type:   MIPS Linux Kernel Image (gzip compressed)
   Data Size:    1234499 Bytes =  1.2 MB
   Load Address: 80080000
   Entry Point:  80080000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK

Starting kernel ... <hangs indefinitely>



Any help will be deeply appreciated.

Hi,

Check your baudrate console on your serial conf file...or the start
address... I feel the problem is in the linux image...

Well, I'm not familliar with the MIPS system but the load address and
entry point look suspicious. According U-Boot README and my own
experience they should be either 0 (newer linux kernels) or 0xc (older
one). Did you use mkimage on your own?

Any further notes/debugging statements also are appreciated. Please try
to enable boot progress report (CONFIG_SHOW_BOOT_PROGRESS) to make sure
that not u-boot is the culprit.

Also good point to look for (rtfm): use linux image map file
(System.map) for log_buf and try to read from given address -> some 
information what might have gone wrong *before* the kernel was able to 
establish a terminal connection. This requires some debugging facility.

Please tell us something about the environment (embedded, console etc).

ok.
