Access SPI flash on the Papillio One board from my RTL

2 posts in this topic

Hi,

Is it possible to access the SPI flash on the Papillio One board from my Verilog code?

Some part of the  flash is taken by  the bitfile for loading FPGA configuration, and I'd

like to use some free flash blocks (a few hundred bytes)

My RTL receives data from a UART interface, processes it (SHA-1) and needs to store

the signature on non-volatile storage. If not, I will  have to get a  separate SPI flash

chip for storage.

Thanks

Hi,

You can store anthing you want after address 0x60000 for Papilio Pro and address 0x46000 for Papilio One.

ZPUino also uses this area, so you may need to push it a bit further if you intend to use it as well.
