Re: SD card on GPIO7..to GPIO11 of ESP-WROOM-32
I'm thinking now that there might be a terrible hack to support SD card on the SPI flash pins, if you don't care about read/write performance. Basically, all the code we need to run a single SD command is placed into IRAM, and we disable flash cache for the duration of the command. Something like t...
