It is possible to configure u-Boot at build time so that it will ignore
any character from the console and always do autoboot. a u-Boot
configured in this way is used, for instance, for secure boot.
Since you do not know the options your board u-Boot was built with,
the best solution is to perform a JTAG recovery with CodeWarrior.

Check your RCW to ensure you are not doing a secure boot.
