Problem replacing external crystal oscillator.


hi all,

i working on project involves uart communication @ 460800 baudrate. this, 16mhz clock frequency wasn't apt. replace external oscillator 14.7456mhz crystal oscillator.

but can't arduino (mega2560) board communicate pc.

what should make pc recognize arduino new crystal?

thanks!

recompile bootloader correct clock frequency , upload using programmer .
