Re: [U-Boot-Users] u-boot kernel parameters

In message 43E8ED18.2050208@sbcglobal.net you wrote:

1. Pass a boot command line 'console=/dev/ttyS0' from your bootloader

or have it compiled in via 'make menuconfig' Check your custom serial driver for the exact TTY device template name (i.e., /dev/ttl0, /dev/ttyAS0).

Alternatively, try using a post mortem dump of the lug buffer to see what might have been prited to the console buffer. See the FAQ for details.

4. Make heavy use of on-board LED indicators by calling ioremap() and

poking your virtualized hardware register location to flip on the LED indicators.

I strongly recommend *against* doing this, at least unless you know *exactly* what you are doing (and then you don't need this because you will use a BDI2000 anyway). I've seen to many reports of "Linux crashes when enabling the MMU" that were cause by exactly such attempts.
