P0.00 toggled on SDCard read

I can't see any particular reason for why P0.00 should behave like that. Is it possible to send the project, then maybe I can take a look at it.

Best regards,

Edvin

I might also mention that this only happens with SDC access - the display using SPI is fine. It almost feels like a DC pin is getting toggled on transfer or something.

I'm using a custom board. Clock source is set to the internal RC.

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,

Edvin
