MCF52259 Demo Board UART ISR Warning Message.

Hi All,

I have been trying to do uart isr by copying and pasting from cf init file. I cannot just use p.e. because it won't let me do continous adc. Therefore, I am copying and pasting from different files. I don't have it working yet and I am getting this warning message when I compile:

"__InterruptVector(.vectortable) in file M52259DEMO_sysinit.c is referenced but has not been written.

Check your linker command file."

Could you help?

Thank you,

FWFan

Also, this is my internal_ram.lcf.
