case about nRF54L15 SPI and P2

[peter.min]

Hi,

How to implement two sets of SPI on the NCS v3.0.0 nRF54L15 P2 port? If it can be achieved, please provide the corresponding IO ports for these two sets of SPI.

Kind regards,
Peter.Min

Hi Peter

You can follow the pin assignments "dedicated function" tab in p.841-843. 

For reference, you can use the following config with for example SPIM20 and SPIM21:

SPIM20:

CS -    P2.00
CLK -  P2.01
SDO - P2.02
SDI -   P2.04

SPIM21:

CS -    P2.10
CLK -  P2.06
SDO - P2.08
SDI -   P2.09

Best regards,

Simon

Hello Simon,

Could you please review the latest post under this private ticket  (Missing Ticket) 

359159

In particular, the question about your recommended SPIM21 configuration NOT working in BLE companion configuration

SPIM21:

CS -    P2.10
CLK -  P2.06
SDO - P2.08
SDI -   P2.09

Could you please explain from the https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/chapters/pin.html

which exact section would explain why the above recommendation would NOT work?

Thank you and kind regards,

Jamal
