Rafal Posted March 4, 2019 Share Posted March 4, 2019 Hi everyone. I have nano pi neo core 2 with ARMBIAN 5.75 stable Debian GNU/Linux 9 (stretch) 4.19.20-sunxi64. I try to change i2c speed from 100 000 to 400 000. I try: sudo fdtput -t i sun50i-h5-nanopi-neo-core2.dtb i2c0 clock-frequency 400000 Error at 'i2c0': FDT_ERR_BADPATH Anyone have idea how to change i2c speed?
