- GPIO buttons are slow to respond
Known Hardware Issues
1. Left/Right Audio channels swapped on line-out jack
- Workaround: edit /etc/asound.conf to swap the channels:
# Swap L/R channels for MinnowBoard Rev A boards pcm.!default { type route slave.pcm "cards.pcm.default" ttable.0.1 1 ttable.1.0 1 }
2. The silkscreen for the RTC battery polarity is incorrect on the MinnowBoard.
- Workaround: No damage will occur if you insert the RTC battery backwards.
3. VBUS detection doesn't work. It appears the issue on the PCB level even after patching necessary drivers. One needs to remove the bootstrap resistor R229. The BIOS seems to work without it. More details are described in this blog post.
