We noted a problem usign the UART1 and 2, we develop a simple linux application that opens a serial port at 460200 BAUD but the measure of period oa a single bit is around 410/420 KHz (about 10% less).
This behaviour corrupts the comunication with the second uC (that we use). The bit period of this second uC is correct.
We are using the uboot and the kernel released with the sdk 5.02.
We haven't change any initialization register, but it seems that tha internal PLL was not locked and so it derives.
Can help me to resolve this issue.
Thank's
