Description
You may receive this error if you are trying to program a flash device using the Parallel Flash Loader (PFL) and the flash has not been tested and verified for use with the PFL. All CFI flash devices that have been tested can be found in Table 3 of the Parallel Flash Loader Megafunction User Guide (PDF).
A possible solution around this error is to define your flash device using the "Define CFI Flash Device" utility. With this utility you will have to add the ID and timing information for your flash device which is available in the flash device datasheet. Once you have entered these parameters this error should no longer appear when trying to program the flash device.
