If you find any problem in the proper working of UDOO BOLT, please consult this section.

My UDOO BOLT doesn't boot or restart itself continuously

If your UDOO BOLT does NOT boot or restarts all the time, please check the following points:

  • When the power jack is inserted the board does not start automatically. The power status LED is yellow/amber/orange and the board is in the power off state. To turn on UDOO BOLT you have to press the small power button on the front of the board. The status LED turns green when the board is powered on. Check the power button position in the Hardware Reference - Overview page.

  • Check the power source you are applying to UDOO BOLT. Please, follow the Power Sources page or consult the User Manual to learn more about the power supply needed by the board for normal operation.

  • Check that the restore factory configuration switch is in the right position for normal operation, otherwise the board will restart continuously. You can find info about that switch in the BIOS-UEFI Firmware page or consulting the User Manual.

I can't install Linux distros on eMMC

If you are trying to install a Linux distribution on the UDOO BOLT eMMC but it is not seen by the installer wizard, please follow the eMMC Usage and Installations section in the Linux - Known issues page. Probably the Linux distro you are trying to install use a Linux Kernel older than the 5.2.5 version.
A Ubuntu 19.04 optimized version for UDOO BOLT that solves this issue is downloadable from the Linux section.
