Setting 115200baud on QE128 using internal oscillator

abhijit_78 — Thu, 17 Jul 2008 12:00:59 GMT

Hi,

I need to set 115200bps on my QE128 board using internal oscillator. I am using processor expert to generate the code and have set internal oscillator freq to 36KHZ to get a bus clock of 9.216MHZ which can then easilty generate the required baud rate of 115200.

However, the actual bus clock that i get is 8.35MHZ and hence the baud rate is also not correct.

Pls suggest.

Thanks.

Thanks for the information.

I am now able to communicate at 115200baud.
