Regular ContributorHI,
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.
Regards,
