Bootloader to Application switching troubles ....

Hello,

I have a home-made bootloader on a lpc2378 that upgrade the firmware
from a SD card. It works well except there's some troubles that
appears when the application is launched.

The interrupt vectors seem to be well remapped to RAM, since the
software part that used interrupts are OK.
But , I have trouble with the UART for example : no or random
characters are sent. I seems like there's troubles with the clock
settings.

Is there particular points to consider when you set the clock
controller twice ? (at the boot time and in the startup of the
application)

Thanks in advance !
