Re: Trouble with motion

The power supply is good for 1.2 Amps and measuring the supply volts it is healthy on the Test point at 4.9 Volts. I believe, although not having one of the new ones yet, that the two poly fuses F1 and F2 that supply the USB ports have been taken out on the new boards and shorts have been fitted in...

Re: Trouble with motion

I know it is the standard answer but have you checked you have a good power supply. I had problems initially with Motion doing some random stuff but since getting a better power supply and moving the camera to a 4 way powered USB. it seems to run fine. Also - I got one of the new UK build Rpis yeste...

Problem with Iceweasle - viewing swf files with new distro

I have been using Iceweasle to view .swf files created by Motion, without any significant problems, but having upgraded to the 18-9-12 distribution and re-installed Motion and Iceweasle, Motion works fine but Iceweasle seems to have lost the ability to cope with viewing .swf files.
