iMPACT SPI Flash Programming Support for Spartan 3E

Hi,

iMPACT tool supported Numonyx (Micron) and Atmel SPI Flash are obsolete. We have used M25P80 to configure Spartan-3E on a few designs in past year and now need to find out in there is a direct replacement?

Thanks,

Michael

Re: iMPACT SPI Flash Programming Support for Spartan 3E

Hi michael@7815

 

  • We do not have a replacement recommendation for M25P80.
  • I will suggest you, to check for similar flash from same manufacture; as mostly manufacture try to make them backward compatible.

For example: "W25Q80DV" compatible with "W25Q80BV" seems to have the command set together. It is possible to avoid ID check by setting environment variable XIL_IMPACT_SKIPIDCODECHECK (Note: Winbond flash W25Q80DV is supported by Xilinx.)

Command set for W25Q80DV is provided in Chapter8 : Instructions in W25Q80DV datasheet (Page 18~21)and for W25Q80BV is provided in  Chapter 6.2 : Instructions  W25Q80BV Datasheet (Page17-20)

 

Note: This SKIP IDCODE workaround is not officially supported by Xilinx.

 

Regards,

Bhushan
