Hello,
I have some issues to do work a VL53L1X with NRF54L15 dev board.
Here are my codes
# Configuration de la Console (Sortie sur Port COM USB) CONFIG_SERIAL=y CONFIG_CONSOLE=y CONFIG_UART_CONSOLE=n # Désactivation ABSOLUE de RTT (sinon rien ne sortira sur l'UART) CONFIG_USE_SEGGER_RTT=y CONFIG_RTT_CONSOLE=y # Driver Capteur CONFIG_PRINTK=y CONFIG_GPIO=y CONFIG_I2C=y CONFIG_SENSOR=y CONFIG_NEWLIB_LIBC=y CONFIG_VL53L1X=y # Support Mathématique (Évite les crashs de calcul) CONFIG_FPU=y CONFIG_CBPRINTF_FP_SUPPORT=y # Mémoire (Le driver VL53L1X est lourd) CONFIG_MAIN_STACK_SIZE=4096 CONFIG_LOG=y CONFIG_LOG_DEFAULT_LEVEL=4 CONFIG_TFM_SECURE_UART=n CONFIG_TFM_LOG_LEVEL_SILENCE=y

And here is the RTT console response :

Someone can help me please?
Thank you !
