nRF52840 PIN 0.19 does no work for SPIM CLK

[Mathangopal]

Hi. I am trying to use PIN 0.19 as my SPI CLK but it is always low.

Previously, I tried to change the pin to 0.26 and it works.

Is there any other configuration required for this pin?

 

Appreciate the help.

Thank you.

Hi,

Did you measure the pin on the pin header on the DK? This pin is connected to the QSPI External memory on the DK, and is not connected to the pin header. You can connect it by soldering some solder bridges, as described in the link.

Best regards,
Jørgen

Yes I did measure the pin and it is always low. I did not know it is connected to the QSPI External memory. Thanks for the info.
