When should I custom one SPI Flash with Lattice Diamond Programmer, if the sector format is mixed with 4K-byte and 64K-byte, how can I do it?
In fact, Page programming mode is widely supported in various SPI flash as the basic programming mode, and that's the only way Lattice Diamond Programmer supports. The 256-byte \u201CPage programming mode\u201D will be used by default.
If the SPI Flash supports 256-byte "Page programming mode", to custom one SPI Flash with Lattice Diamond Programmer, you can select "unknown" for the option "Byte Per Sector", and set dedicated values for other options according to the datasheet of the SPI Flash. Then you may find the new device from the supported flash list "SPI Serial Flash Custom" and test it with your test board.
