I've added an SD card slot to my Raspberry CMIO board and verified that the SD card shows up when using the latest Raspbian image and the dtoverlay=sdio config.txt option. Seems to work fine.
Then installed Ubuntu Core 16, added dtoverlay=sdio, verified that /proc /device-tree shows the overlay but no further luck. The SD card does not show up. Am I missing something? Can you verify that it works for you with latest core 16 and kernel 4.4.0-1126-raspi2? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1823655 Title: Second SD card on RPi3 CM3 on Ubuntu Core 18 does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1823655/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
