we’re having problems running one of the UARTs (UART1?) on the AM3517 dev board at 921.6 kb. The measured rate is closer to 1Mb, about 8% high. We believe it’s causing us communication problems. It almost sounds as though the driver is loading the wrong divisor value, or similar. At lower speeds (e.g. 230.4 kb) the frequency is ok and within 1% or so.
