    1. Are you trying to boot from device? or is it during a normal read from flash
    2. Are you seeing this issue in your custom board/ TI Control card /  Launch Pad?
      • If custom board can you please share the board schematics?
  • Do you see any pattern in when 0xCC prints?
  • What is the part number of flash you are using?

    • Thanks & Regards,
    Rijohn
