FAQ/The phone stops while booting, only power cycling resolves the issue

Answer

If you experience such behavior the following might explain it:

1. Bus Error
   • Description: If bus errors occur during the linux kernel start-up it might get stuck in the so called "Bus Error Trap Handler". This happens only if another bus error occurs which is an extremely rare case
   • Workaround: Power cycling the phone.
2. Serial Console:
   • Description: The serial console might get stuck in the so called "uboot prompt" while the phone is booting up. This can be caused by invalid communication patterns on the serial interface.
   • Workaround: Update the phone's firmware and bootloader version:
     • snom300
     • snom320
     • snom360
     • snom370 bootloader image is coming soon
