Hi all, I have a 4DPI-24-HAT (2.4" HAT primary display) and connect it to the UP board, but there is no display at all. Is there any settings I need to configure on the UP board? Can anyone help to resolve my issue..? Thank you..

    Hi
    In general, SPI and I2C devices are not discovered automatically by the host system (be it Raspberry Pi, UP, or any other board) and special configuration and/or kernel driver code needs to be added to make them work. You'll probably have noticed in the datasheet for this display that a special kernel, which was prepared by the board vendor, is needed to use it on the Raspberry Pi. I'm not personally familiar with this specific HAT, so am not sure what would be needed to enable it on UP. However, in general, we will be adding some new features in ubilinux soon to make it easier to add support for many SPI- and I2C-connected HATs.
    Regards,
