How to use online clock tool generate BOARD_BootClockFROHF48M() function?

hotashu — Tue, 04 Jul 2017 08:07:20 GMT

I use online clock generate tool to generate clock configuration file.

I want to generate configuration files like BOARD_BootClockFROHF48M(), BOARD_BootClockFROHF96M() . But in generated clock_config.c/h, those functions are not there, only BOARD_InitBootClocks() and BOARD_BootClocksRUN()

please tell me how to proceed to generate other functions that I need. Thanks.

Hi hotas,

- About " BOARD_InitBootClocks() " , it just a function name ,and it is matching with the code of SDK project,

when we create a simple SDK project, it will includes the function of " BOARD_InitBootClocks() "in main.c file:

- After you configure clock on MCUXpresso clock tool, the code in clock_config.c and clock_config.h

will be changed automatically refer to your configuration. For example :

Hope it helps

Have a great day,

Hi,

The problem is that your configuration is for plain processor but not based on board.

for example,

BOARD_BootClockFROHF48M() can be generated for configuration "LPCXpresso54680", but not for "LPC54608J512 "

According to developer "The pre-set configurations are available and tailored only for boards, if you would use a processor that does not have any board available, you would need to add functions and configure clocks manually in clocks tool."

you can switch configuration in "MANAGE" tab.

Have a great day,
