Standard 1 bit SPI mode for spi_flash not available?

Open danielkucera opened this issue 7 years ago • 2 comments

I spent last 10 hours trying to figure out how to make my onboard M25P80 work with misoc but I didn't find a solution. It seem that it supports only standard 1bit SPI transfers while misoc only supports x2 and x4 modes. Is it really so? Would it be possible to support basic mode to cover all SPI flashes?

LiteX includes a 1bit SPI Flash version here -> https://github.com/enjoy-digital/litex/blob/master/litex/soc/cores/spi_flash.py#L114

I believe it's covered here, so will be available if PR will be merged: https://github.com/m-labs/misoc/pull/130/commits/7d9a09c0f22fb740e2672ccf500e0e8aff5b80b6
