Hi,
You can control BB-RETIMER parameters using the Host Processor Interface (HPI).
Please refer to BB-RETIMER documentation to check what parameters can be adjusted.
Also, please let me know which eye diagram test is failing.

Hi, Pranava
USB3.0 eye diagram test is failing
Do you mean we can use HPI to write BB-RETIMER parameters to improve signal quality?

Hi, Pranava,
HPI document doesn't describe about BB-RETIMER signal quality adjustment.
Can you give me some info about this?

Hi Ivan,
As per my previous comment, please check BB Retimer documentation regarding the parameters that can be configured. HPI provides an interface for EC to communicate with BB Retimer via I2C interface.
May I know if you have appropriate documentation of BB Retimer?
