the software may still be configured for the older PI .
When the move to PI 2 happened, some of the PI pins regarding the SPI bus etc changed and this may be your issue, look for an updated driver,, check their web site to verify it it has been confirmed working on PI 2
Any luck? I'm interested in that screen for my projects.
If not, you might try the steps here: I Can See Clearly Now! With the 4D Systems 2.4" Touch Screen for the Raspberry Pi
If this is not working, you may try "safe mode" and disable some things...
If you do this, bootloader will ignore the
config.txtfile (except from
avoid_safe_modeoption which can be used to disable this feature) and will try to boot
kernel_emergency.img(if available) instead of
kernel_emergency.imghas special emergency
initramfsbuild in and it will boot to this busybox based OS so that you can fix the problems in your OS manually (or change kernel boot parameters to run runlevel 1 at next boot). Remember to run
syncbefore powering down since
shutdowncommands may not work.
I purchased a 2.4" HAT (2.4" HAT Primary Display for the Raspberry Pi) and can't seem to get it working. I have the Pi 2 and followed the instructions on the directions, then the website, to install the required package to get the screen working. Unfortunately, when I get everything installed the screen doesn't work and the software appears to cause the boot to hang (NOOBS OS) and there's no way to boot the system. I/m forced to reinstall NOOBS with a clean install.
