Look at the dts files in build/zephyr, there is stuff enabled on i2c1 or spi1 interface. You can have only one enabled on a shared peripherial.

oh yes, but unfortunately, I have the same error

CONFIG_TFM_SECURE_UART1=n
CONFIG_TFM_LOG_LEVEL_SILENCE=y

/opt/nordic/ncs/v2.5.0/zephyr/include/zephyr/toolchain/gcc.h:87:36: error: static assertion failed: "Only one of the following peripherals can be enabled: SPI1, SPIM1, SPIS1, TWI1, TWIM1, TWIS1, UARTE1. Check nodes with status \"okay\" in zephyr.dts."
   87 | #define BUILD_ASSERT(EXPR, MSG...) _Static_assert(EXPR, "" MSG)

I don't know if it's important but I tri to use PO.23 and P0.24 for uart1

Hi Simon,

It seems there’s a mismatch between your KConfig symbols and your device tree. In prj.conf you’re referring to UART0, but in your overlay you’re referring to UART1.

Best regards,
Benjamin
