LPUART FreeRTOS peripherals config incomplete

koj — Thu, 06 Mar 2025 17:07:46 GMT

While configuring the LP_FLEXCOMM LPUART peripheral in FreeRTOS mode, the srcclk field is not populated correctly.

The clock source frequency is selected in the drop down list but doesn't appear in the peripherals.h nor the resulting config.

lpuart_rtos_config_t LP_FLEXCOMM2_rtos_config = {
.base = LP_FLEXCOMM2_PERIPHERAL,
.srcclk = 0UL,
.baudrate = 115200UL,

No errors are reported Problems windows.

Hi @koj

The srcclk value in lpuart_rtos_config_t is used to config the SOURCE CLOCK for LP_FLEXCOMM,

If you use the LP_FLEXCOMM2.

Please config the clock for LP_FLEXCOMM2 first.

That is exactly what I did and the generated code is incomplete.

There is a bug in the tool.

Here's the output from peripherals.c where you can clearly see the timingConfig in the YAML is configured but that config is not applied to the .srcclk.

Hi @koj

Thanks for your information, i will report this issue.
