P0.00 toggled on SDCard read

[hamster]

Using the sdk15 and softdevice 132 v6, I'm setting up an app to read and write to an SD card that uses SPI1 (SPI0 is used by a display).  Everything is working great, except that an LED that I have connected to P0.00 gets toggled on during SD card reads.  It works well to show SD card activity, unfortunately that LED is to be used for a different function.

I cannot seem to find anywhere in the setup or config that specifies an activity indicator or some other pin other than SCK/MISO/MOSI/CS, which are all not P0.00.  Any hints?

I also set the BSP_LED_0 to something other than pin 0, but it did not suppress this issue.

Hello,

Do you use the DK, or a custom board?

I assume that you use a custom board, because on the DK, P0.00 and P0.01 is connected to the LFXTAL.

Do you have an LFXTAL on your board? In that case, what pins are they connected to? If not, do you use the RC Oscillator instead of the LFXTAL?

P0.00 is not by default connected to any of the LEDs, so you shouldn't have to worry about BSP_LED_0 (It is usually set to P0.17).

 

Best regards,
