F29H85X-SOM-EVM: UART max speed

Lenio Cacula
Genius 17020 points

Part Number: F29H85X-SOM-EVM
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

SysConfig limits the speed of the UART to 921600 baud. The datasheet mentions in the UART section 6.19.9, "Programmable baud-rate generator allowing speeds of up to 12.5Mbps for regular speed (divide by 16) and
25Mbps for high speed (divide by 8)". Is the speed mentioned in the datasheet achievable? If so, does it need to be manually configured outside SysConfig?

Thank you!

    Hi Lenio,

    On the F29H85x device, you are correct, the max baud rate of the UART peripheral would be 25Mbps. It looks like the Sysconfig has a dropdown with all the standard baud rates going up to 921600bps. However, to input baud rates higher (or non-standard), you can select "Custom" and type in a specific baud rate, like below:
