Hi all,

I have an ST10F269 TQFP package and when I run with a 32MHz resonator, I can only flash using ST10 Flasher V2.0 at 19200 Baud. When running at 24MHz, I can flash up to 57600 Baud. Any ideas? Thanks.

With a 32MHz clock you need a divisor of 11.5 or 17.4 to get 157600baud so the nearest whole number probably creates too great an error for your PC to read it.

24Mhz however can generate 57600 almost exactly...

see page 88 of the ST10F269 data sheet
