Thnaks for the answer. i2c-dev and i2c-core are loaded as well as i2c-ralink and my i2c driver. How to add CONFIG_I2C_CHARDEV? I added it in /target/linux/ramips config file of my board but it hasn't changed anything. How may I check that the config has really been added? By the way, is there a similar CONFIG for SPI, like CONFIG_SPI_CHARDEV ? > > John > _______________________________________________ > openwrt-devel mailing list > openwrt-devel@lists.openwrt.org > https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel -- Baptiste _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
