I am working on an example project(SAMC21 Xplained pro) using "Atmel Start" -> EDBG UART. Below are the clock settings from the example and it works great.
now I changed the clock settings to this
and I am facing "Framing Error" problem
Nothing else is changed in the project except the clocks and the Baud Rate is 115200. I presume the clock settings are correct since I didn't get any error/warning notifications.
If I change the CPU clock as show below then it is working again. I am not sure why higher CPU clock is causing such a problem.
Any suggestions would be great.
