Dear
I am wondering how to get valid RX data with TX2 SOM UART2 RX Sampling Timming.
Below is an example waveformserial - UART receiver clock speed - Electrical Engineering Stack Exchange
Do beware that higher speeds will have need for some aspects being more tightly controlled. Are you having issues with a speed in excess of 115200? If so, can you try with two stop bits?
Hi,
Hi,
As its already mentioned, its possible that based on divisor the actual baud rate may be settled to a lesser value. This happens when the divisor is set by either on lower or upper bound of the actual required divisor.
For example:
Source clock Rate: 408 MHz
Required Baud Rate: 4 M
Required Baud Frequency: 64 MHz
Actual Divisor Needed: 6.375
Recommended Baud Frequency: 65.28 MHz
New Divisor Needed: 6.25
Nearest Possible Div (lower side): 6
Nearest Possible Baud Frequency: 68 MHz

Hello oliver30sgx,
Based on your earlier comment of achieving ~7.3 Mbits/S on UARTC (J17) when setting to 8Mbits/s.
Yes its correct. TX2 uartc hardware limits this based on supported tolerance range, clock parent and divisor.
PLLC4_MUXED clock can be used to achieve exactly 8Mbits/s. But UARTC has no support of this clock source.
To achieve exactly 8Mbits/s baud rate on TX2, you need to change to another uart port which has PLLC4_MUXED as possible clock source and set the clock source accord…
