Hello guys,

for the board STM32F407 I want to add pin PA8 25 MHz clk output to Etherent Phy. So that I add the following sentence (1)

 

HAL_RCC_MCOConfig(RCC_MCO1, RCC_MCO1SOURCE_HSE, RCC_MCODIV_1)          into the pinmux.c.

 

The rest of code in pinmux.c I copied from stm32f4_dico, except I configure OTG_HS_DM / OTG_HS_DP as virtual port.

 

The compiling fails at the last step:  `HAL_GPIO_Init' is not defined.

[129/134] Linking C executable zephyr/zephyr_prebuilt.elf
FAILED: zephyr/zephyr_prebuilt.elf

collect2: error: ld returned 1 exit status

 

The pinmux.c is attaced here. the compile is successful without adding the sentence(1).

 

Do you have any idea? or how can I check it further?

Thank you!
