thericcer Posted December 27, 2018 Share Posted December 27, 2018 I purchased a TETRA and out of the box it continuously rebooted when powered on. I figured I hadn't supplied enough power for it to finish the boot, so I used the supplied power adapter. Again, the rebooting continued. So, I decided to monitor the UART output, and discovered that when it finished booting up, the kernel would panic with a kernel page allocation fail. Hmm, bad firmware image from the factory? So I downloaded the factory image, flashed it with the UBOOT recovery website, then it was able to finish the boot. (Whew!) So I decided to start monitoring some networks and fired up PineAP. Reboot. Again I tried to monitor, with both the power brick (plugged in first, in case the on board power chip chooses the first device to provide power and doesn't switch) and the USB-Y cable, Reboot. Tried a 12v 4a capable power supply, same reboot issue when the radios are turned on. I've tried to supply this thing with countless configurations of power adapters/USB cables, all of which should be sufficient for the rated input (24w), but no dice. So now I'm starting to think that I got a bum power supply on the board (I'm sure there is some switching supply on board to supply the chip voltages.) All of this is to say, has anyone else suffered from these issues from a Model MK5.8 TETRA? Quote Link to comment Share on other sites More sharing options...
