New ATXRaspi reboot function

ATXRaspi will start to ship with a new reboot function in addition to the shutdown function it had since inception. This was implemented because it was a cool feature to have and also suggested by several ATXRaspi users. See video above for a full overview and setup guide for ATXRaspi.

This will be in revision R2.6 boards but until that is released, revision 2.5 boards that have the reboot function will have a blue dot on the main chip (see photo above). The differences are the following:

  • to reboot: hold the button pressed for at least 0.5s and and less than 2s. The button backlight will dim once the reset threshold is met. Release the button and ATXRaspi will emit a 500ms HIGH pulse on the SHUTDOWN signal pin. It will then blink the button backlight for up to 1 minute while waiting for the Pi to reboot and the BOOTOK signal to be restored by the shutdowncheck script (to become HIGH again).
  • to shutdown – nothing changes: hold the button at least 2s. As before, the button backlight pulses slowly while the Pi shuts down. Once the shutdown is complete and BOOTOK signal goes LOW, ATXRaspi waits a few more seconds and cuts power off to the Pi.

The shutdownchecksetup.sh install script was¬†updated to support the reboot function and is backward compatible with all previous ATXRaspi revisions. Here’s a photo of the required wiring to the GPIO and an example wiring of the chrome button offered at the LowPowerLab shop:

  1. Hi, I don’t want the reboot-function on my power-switch. Can I deactivate that function in the script?
    Kindly regards, Sebastian
