Enable 4 SPI instances in nrf52840

[Shreya J B]

Hi,

I am using nrf52840. we have already used 3 SPI instance (SPIM1, SPIM 2, SPIM 3). wanted to use one more SPI instance i.e. SPIM 0. but if I enable this I am getting                                                                                                                                                                                                                                                                                                                                                             " 'NRF_DRV_SPI_INSTANCE_SPI_INSTANCE_0' undeclared here (not in a function)" this error. 

can you please help us to solve this issue.

Thank you,

Hello,

Which pins are you using for setting SPI0 as instance? Are the pin numbers correct in overlay according to the board connection?

Sometimes other peripherals also use the same pin as SPIs. Have you checked if there is any overlapping of pin using?

Thanks.
