Hey all,
I am facing problem in configuring my board in I2c protocol. When i configured the same board in standard mode it is working fine. Rest of the settings for pins(pull-up) ,rise time and fall time are same in both the files.
Also attaching waveforms for both the mode. Can anyone suggest me what can be done to make the board work in fast mode as well.
Thanking you in advance.

The pullup resistors on the SDA/SCL lines are insufficient for fast mode. Replace them with lower valued resistors. 2.2 kOhm is typically fine.

Dear TDK,
Thanks for your suggestion. Will implement the changes within the circuit and let you know if it is working or not.
👍.
