Hi all. Can you guys help me.I am using beaglebone black i2c2 pin 19 and 20 of p9. Somewhere in the net it was told i2c2 has told accessed with i2c-1 in /dev folder. I am booting default amstrom linux from emmc. Hardware is completely checked and verified. I have connected 3 io expansion modules to i2c bus. I can communicate to them by i2ctest commands from command line. But the problem is with the file writes. I cant write to /dev/i2c-1 file with "write" function. The file descriptor doeant have an error. Also the ioctl calls doest make any errors. But the write function is having problem. And thus I cant access i2c bus in application layer.
