Takeyoshi, Hey, in case you are interested, I got the SDMMC driver port working for reading data today. It's quite a mess, and on a private branch. I will try to get it working for writing, clean it up, and push it to this branch in a few days.
Thanks so much for your help!! cheers adam On Mon, May 4, 2020 at 3:29 PM Adam Feuer <a...@starcat.io> wrote: > Takeyoshi, > > Hi, I've been working on the SDMMC driver off and on.
