Hi Chunbin, If you look thorugh https://github.com/ARMmbed/mbed-os/blob/master/targets/targets.json NUCLEO_F429ZI has "extra_labels_add" field, that has STM32F429ZI, which is your particular target.
The way to follow this is os/targets/TARGET_STM/TARGET_STM32F4/ and then under TARGET_STM32F429xI/, you have TARGET_DISCO_F429ZI and TARGET_NUCLEO_F429ZI. Assuming you have TARGET_NUCLEO_F429ZI, look in PinNames.h. If you want to configure a different pin than you may have to specify a json file as described here: https://os.mbed.com/docs/v5.9/reference/configuration.html. Though, I don't think that is what you are trying to do here.
Hope this helps. Please let us know if you have any further questions.
Thanks,
Naveen, team mbed.
