iMPACT SPI Flash Programming

Hi,

We use a flash memory of Winbond, PN W25Q64BV, which is already obsolete, for Spartan-6.

We are looking for a compatible component and we are considering taking the W25Q64JVZEIQ, but we found discrepancy in the following links:

https://www.xilinx.com/support/documentation/sw_manuals/xilinx11/pim_c_introduction_indirect_programming.htm

https://www.xilinx.com/support/documentation/sw_manuals/xilinx12_1/pim_r_supported_spi_bpi_proms.htm

https://www.xilinx.com/support/documentation/sw_manuals/xilinx14_7/pim_r_supported_spi_bpi_proms.htm

Doe's iMPACT support the W25Q64JVZEIQ for Spartan-6?

Thanks.

Re: iMPACT SPI Flash Programming

Hello @adihrw

W25Q64JVZEIQ is not supported by iMPACT tool.

You can test non supported SPI PROM using skip ID Test (Note: This method is not officially supported.)

For more information check https://forums.xilinx.com/t5/Virtex-Family-FPGAs/SPI-NOR-FLASH-MT25Q-not-listed-in-Impact-14-7/m-p/800669#M26018

Check W25Q64JVZEIQ SPI flash Parameter’s (IO Voltage, Command set, IO Mode, features ...etc.…) are compatible with Xilinx supported flash then Non-supported flash must be able to configure/Startup/Boot FPGA. You can cross-check Xilinx supported flash’s command set with you selected non-supported flash. Command set are provided in datasheet of flash.

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)
