Hi,
Not sure i'm on the right forum. I have a starter kit of am335x running on my desk. I'm trying work on the I2C on this board, I have a device (electronic configuration plug) connected to the J8 pin (or port?). I have checked there's only i2c-1 is enabled from the terminal. But when I try to run these commands;
root@am335x-evm:/test# i2cdetect -F -y 1
Functionalities implemented by /dev/i2c-1:
I2C yes
SMBus Quick Command no
SMBus Send Byte yes
SMBus Receive Byte yes
SMBus Write Byte yes
SMBus Read Byte yes
SMBus Write Word yes
SMBus Read Word yes
SMBus Process Call yes
SMBus Block Write yes
SMBus Block Read no
SMBus Block Process Call no
SMBus PEC yes
I2C Block Write yes
I2C Block Read yes
root@am335x-evm:/test# i2cdetect -y 1
Error: Can't use SMBus Quick Write command on this bus
root@am335x-evm:/test# i2cdetect -y -r 1

it seems I2C module is not loaded? Any idea how I can load the I2C module?
Any help?
Thanks.
