MCUXpresso ConfigTools generated files

Hi,

I am working on evkmimxrt1020_lpspi_interrupt_b2b_master project. In the clock_config.c file there is a big section labelled as the following:

/*******************************************************************************
********************** Configuration BOARD_BootClockRUN ***********************
******************************************************************************/
/* TEXT BELOW IS USED AS SETTING FOR TOOLS *************************************
!!Configuration
name: BOARD_BootClockRUN
called_from_default_init: true
outputs:
- {id: AHB_CLK_ROOT.outFreq, value: 500 MHz}
- {id: CAN_CLK_ROOT.outFreq, value: 40 MHz}
- {id: CKIL_SYNC_CLK_ROOT.outFreq, value: 32.768 kHz}
- {id: CLK_1M.outFreq, value: 1 MHz}
- {id: CLK_24M.outFreq, value: 24 MHz}
- {id: ENET_500M_REF_CLK.outFreq, value: 500 MHz}

...

I have two questions:

1. I don't see any of the settings in the section in any of the C functions. So how does these setting take effect?

2. I open the clock config tool and without changing anything just click update the project button the new clock_config.c is different from the original one, why is it?

Thanks!

Hi Tom,

That section is used by the MCUXpresso Config tools, the configuration shown there is implemented in the BOARD_BootClockRUN(void) function:

I have tested opening the clocks tool for the evkmimxrt1020_lpspi_interrupt_b2b_master project, clicked on Update Project and there was no change in the source code, what changes are you seeing?

Hope it helps!

Hi Carlos,

Here is my setup:

SDK_2.x_EVK-MIMXRT1020 version 2.4.0 Manifest Version: 3.3.0

Example project imported: evkmimxrt1020_lpspi_interrupt_b2b_master

The clock_config.c from the SDK example and the preview code from the clock config tool are attached.

Thanks!
