papilio one spi flash replacement

[armin 0]

Hello

I decide to assemble papilio one myself, is it possible to replace it's original spi flash with AT45DB161D-SU or AT45DB321D-SU?

Thanks.

Any SPI flash that is supported in the Xilinx datasheet for the Spartan 3E will work. But not every flash chip is supported by the papilio loader application.

Hello

Thanks for your answer, atmel AT45DB 'D' series are mentioned to support fast read and read array commands but not read command.

Will it be ok?

I've never tried it before so I cannot say for sure that it is ok...
