I am wondering how to properly configure the LPUART clock frequency on a KL17. I see in the driver where I can set the clock source:
* 00: Clock Disabled
* 01: IRC48M
* 10: OSCERCLK
* 11: MCGIRCCLK
Currently we have IRC48M, but since this seems to be an internal clock, we believe it may be inaccurate because we're seeing occasional junk characters on UART. I could change it to OSCERCLK, however with a 32K oscillator we won't be able to properly hit 115200 baud.
Btw this is using KSDK 2.0
Hello Kenneth,
You can refer to the demo under KSDK :boards\frdmkl43z\driver_examples\lpuart
If still can not work , please tell me the part number of your chip, and show the code about
how to configure.
Hope it helps
Alice
