Hi,

I change the default pins(8675-->3102) in pca10040.h

but my spi still cant work

Typically this is in the board file (boards.h), in your case I expect you can find it in pca10040.h.

thank, i flipped over my DK and see

and follow https://devzone.nordicsemi.com/f/nordic-q-a/55367/disable-uart-of-nrf52

after disable all uart-relateds in the sdk_config.h and Exclude nrf_drv_uart.c from build it works

but now i want to use uart for other function

I change the HCI_UART_ PINS in sdk_config.h and also PIN_NUMBERs in pca10040.h

but my spi dont work this time

do you know how to change the default uart pins?

If you flip over an nRF52-DK you can see the default connection and usage for GPIO's, for instance pins 5-6-7-8 are by default setup to be used as UART pins. Likely you have exported your project from the nRF52-DK, and these pins are still assigned to be UART pins.

Best regards,
