Kernel panic / squashfs errors


Perimiter
 Share

Recommended Posts

I'we had my Pineapple Tetra for two weeks and I'we spent most of the time just trying to get it running, and It's just getting worse every time.

I get squashfs errors, unhandled kernel unalinged access errors.

After a few reinstallations of tetra_factory.bin it boots up, and if I leave it after basic config it runs about two hours before rebooting and i need to reflash.

It has been running mostly on the wall adapter, but I'we tried running it on my labratory powersupply at work on 12.0v connected to the 5.5mm connector, to 2.1amp usb power packs, 5.0v from lab supply to the micro usb ports (and even 5.10v as most usb power packs deliver that). No change in the situation.

Hi. The first logfile in the zip file contains several attempts to load tetra_factory.bin and boot after loading.

It finally succeeds, but if i try to do anything active after some time I get squashfs errors. The same errors occur after a few hours of idling also.

When they have appeared I usually need to run firmware recovery to get it to boot again (tried this > 15 times).
