The data rate of AUX in DisplayPort IP

[SYang9]

Dear Sir,

 about the DisplayPort RX, can we get the information of Package error or Bit error? Could you share how to checks SI from Intel?

HI,

If you are using DisplayPort example design, then we do have debug capability to print out MSA log that contains bit error rate for each data channel.

• Example of MSA log screenshot is shown in below AN793 page 20
• https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an793.pdf

Steps to enable the MSA log dump is below

• goto DP example design software folder, look for config.h
• Ensure below parameter is set to 1 
• #define BITEC_STATUS_DEBUG     1 // Set to 1 to enable MSA and link status monitoring 
• Program design sof file
• Open NIOSII shell terminal
• type nios2-terminal
• press "s" keyboard key
• It will print out MSA log

Thanks.
