I'm having some problems with the I2C bus-0 on the Cyclone V SX SC SoC development board.
I use this I2C bus for my capacitive touchscreen (address 0x40), what is working but after a some time the entire I2C bus-0 is stuck, because of one device keeping the SDA grounded. Which resolves in to this error:Only way to get rid of this error is by cold rebooting the development board.
On the I2C bus are 10 devices. 9 of these are known to me but the device with address 0x17 is unknown to me.
I did like to know what device is using address 0x17, because I think this is the device that is causing my problems.
If you are referring to this board:
There aren't any I2C devices at address 0x17
See page 2-38 ( I2C Interface) in
I had checked all documents and couldn't find anything about device 0x17. This is because it is simply missing in the manual.
I found out that device 0x17 is the SDI Cable Driver (LMH0303SQx). Would be nice if Intel did update the manual ;)
After removing resistor R442, device 0x17 was disconnected from the I2C bus-0.
This solved some of my problems.
