Hi Rodrigo, Currently trying to build zephyr/samples/drivers/i2c_fujitsu_fram/ demo eg. to test i2c for nRF52840_pca10056. As per your previous email, I added following things in prj.conf CONFIG_I2C=y CONFIG_I2C_NRFX=y CONFIG_I2C_0_NRF_TWI=y CONFIG_I2C_INIT_PRIORITY=60 CONFIG_I2C_0=y But still getting following error, ../src/main.c:16:17: error: ‘CONFIG_I2C_0_NAME’ undeclared (first use in this function) #define I2C_DEV CONFIG_I2C_0_NAME ^ ../src/main.c:84:31: note: in expansion of macro ‘I2C_DEV’ i2c_dev = device_get_binding(I2C_DEV); ^~~~~~~ ../src/main.c:16:17: note: each undeclared identifier is reported only once for each function it appears in #define I2C_DEV CONFIG_I2C_0_NAME ^ ../src/main.c:84:31: note: in expansion of macro ‘I2C_DEV’ i2c_dev = device_get_binding(I2C_DEV); ^~~~~~~ [19/141] Building C object zephyr/CMakeFiles/zephyr.dir/lib/mempool/mempool.c.obj ninja: build stopped: subcommand failed. Please help me to sort out this issue. Thank You !!

Run ninja menuconfig, go through the settings and set the various I2C options up then it should build.

Works fine with those lines added to prj.conf

Hi to all, I renamed driver name from CONFIG_I2C_0_NAME to DT_I2C_0_NAME. Plus add following Kconfig things in prj.conf. Now everything is working fine. CONFIG_I2C=y CONFIG_I2C_NRFX=y CONFIG_NRFX_TWI=y CONFIG_I2C_0_NRF_TWI=y CONFIG_HAS_HW_NRF_TWI0=y CONFIG_I2C_INIT_PRIORITY=60 CONFIG_I2C_0=y Thanks & Regards, vikrant
