RE: Using SPI00 interface with nRF54L15 custom development board

Hello,

Thank you for your response. Actually, I knew that there are some restrictions on using the pins, but I may have made this mistake.

Ok. I got it. I can't change it then for now. I may try a new version.

Hello,

You need to follow the description in the Configuration table here:
https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/spim.html#d1428e920

For SPIM00 it says: Use dedicated pins on GPIO port P2.

Then going to:
https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/chapters/pin.html#ariaid-title2

For SPIM00 it says: "SPIM00 Has dedicated pins on P2. For 32 MHz operation, the pins must be configured using extra high drive E0/E1 configuration in the DRIVE0/1 fields of the PIN_CNF GPIO register."

The actual pin might depend on the package variant, so you need to checkout in specific for your variant:
https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/chapters/pin.html#ariaid-title4
https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/chapters/pin.html#ariaid-title5
https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/chapters/pin.html#ariaid-title6

So, you can't change MISO or MOSI in this case if P2.04 is SPIM SDI (=MISO) and P2.02 SPIM SDO (=MOSI) for the package variant.
