you can test i2c attaching a sensor like MPU6050 in the i2c pins (TWI4, TWI1, TW5), enable the i2c like in the orange pi user manual (add the overlay in /boot/extlinux/extlinux.com), and use the same command to test the i2c (sudo i2cdetect -y 4), it will show a table with all the i2c devices attached with their addresses, for instance if you are using a MPU6050 it will report the address 0x68, mine it is not reporting the address, it pauses the scanning for five seconds at the column 60 and the row 8, meaning that it is like detecting the address but finally it doesn't reports nothing, so it results with an empty table, also i tried to write and read registers but without success.
Hi, I also tried to run this sensor, tried different ports but to no avail.
maybe you found a way to solve this problem?
