Release Information

The DDR margin firmware and supporting scripts allow visualization and measurement of system margin in the DDR interface on board. These tools enable probe-less measurement of critical data signals to understand the integrity and robustness of the interface.

What's new

  • Firmware update for AM62A/AM62P to fix corner cases where some units had a corrupted eye diagram
  • This would previously result in the script erroring out
  • Script updates for the following
  • Fixed issues with path parsing when files are outside of directory where script resides
  • Fixed corner condition where script would fail with corrupted eye diagram, now outputs warning message 
  • Message: "...log may not accurately depict eye!"
  • Removed preview eye .png generation and display
