UART example change clocks

liqingfa — Fri, 31 Mar 2023 07:29:05 GMT

when i testing the example LpuartFlexio_Uart_Ip_Example_S32K344 , I change the clocks of "CORE_CLK" and "QSPI_MEM_CLK" to 160 Mhz, Result run to "FALSE", I donot know why, but it seem have no relation to UART and Flexio module, them base on "AIPS_PLAT_CLK" and "AIPS_SLOW_CLK"。if i want change clocks to 160Mhz, what to do it can work.

Hi @liqingfa,

The FlexIO module is clocked by the core clk.
