https://devzone.nordicsemi.com/f/nordic-q-a/124205/i2c-does-not-work-with-p0-02-and-p0-03-on-nrf54l15dkFirst, I can use I2C with SCL on pin P1.11 and SDA on P1.12 with NRF54L15DK. But then, when I try to change SCL to P0.03 and SDA to P0.02. I2C does not work anymore. The log for logic analyzer shows that there is only 1 pulse on the SDA pin.
