xobsI ask because I'm only getting that message if I omit "-oremount,rw": https://gist.github.com/xobs/cbc74c3bf44d8c1d103bc6bc82871c9b02:06

CarlFKxobs: this looks buggy: flash, reset, fomu-flash -i shows all ff's, fomu-flash -i again looks legit05:55

felix_hmm, was it intended that fomu-flash is basically a reimplementation of maybe a half of flashrom?09:39
xobsfelix_: I started out using flashrom, but found it inadequate.09:40
xobsFor example, it only supports two-wire SPI.09:41
xobsIt also doesn't have a bit-banged GPIO driver, and I ran into a bug where the Fedora Raspberry Pi kernel driver was driving CS/ high in between packets, so it just flat-out didn't work.09:41
felix_ah, ok09:41
xobsAlso, MOSI and MISO switch which pins do what depending on whether you're talking to the FPGA or the SPI flash.  So we definitely needed to bit-bang it somewhat.09:42
xobsThere's also a dance you need to do by putting the FPGA in reset, or the SPI flash into reset, depending on what you're talking to.09:42
felix_this sounds indeed very useful09:43
