Keep in mind that this is a  board-specific  configuration  which  is
intended  for  the MicroSys CPU86 board only. If it actually works on
your hardware you are really, really lucky.

Usually it just means that your console is not where  you  configured
it. For example, on the CPU86 board you include this code:

...
#elif   defined(CONFIG_CPU86)
#define CONFIG_SERIAL_CONSOLE_PORT      2
#else
...

which maps to SCC2. Do you really have your console port on SCC2?


I think it is generally a BAD idea to copy some  board-specific  code
without  checking CAREFULLY what you're doing. You tried, and you got
what you deserved: a non-working system ;-)
