A. Non-Standard Flash Memories

This section covers advanced topics to support non-standard CFI flash memory. To use the procedures in this section, you must refer to the data sheet for the flash memory device you are using. Ensure you fully understand the CFI aspects of the device.

Some CFI flash memory devices contain missing or incorrect CFI table information. In such cases, the Nios® II Flash Programmer might fail based on the erroneous information in the CFI table. For these devices, the Nios® II Flash Programmer provides the following methods to override the CFI table and successfully program flash memory:
  • Built-in recognition and override
  • Flash override files
  • Width mode override
