Re: Ubuntu / Linaro for Raspberry Pi 2

Whatever it is using, Blender does not start on the standard Raspian, and on this version it starts and I have played with simple modeling and even loaded a video for editing. There really isn't enough memory to do either well, but the fact that it will startup indicates to me this Arm7 version has ...

wintrmute, please give us a heads up here when you get the new one working. I've been happiest with your last one on the Pi2.

Re: Ubuntu / Linaro for Raspberry Pi 2

I did not realize the significance of Blender running on this image. Apparently it doesn't run on either Raspian or the Trusty Ubuntu image because the code they run is backward compatible with the original pi which is ARM6 architecture and the new Pi2 is ARM7. What is significant is that a full ver...

Re: Blender

Thanks Fidelius, it sounds like there may be a solution to both problems one day. Out of curiosity I'm getting ready to load the linaro image and see just how useful Blender is on the four core Pi2. I really wouldn't think it would be a big deal to have different versions of Raspian for the Pi and P...

Blender

I tried out the linaro image on the RPi2 and was very pleased to see Blender ran. It loaded very quickly. I haven't tried to see how useful it is, but I have hopes that it is at least capable of some light video editing and some 3D modeling. I went back to the Raspbian image and was disapointed to s...

Re: Ubuntu / Linaro for Raspberry Pi 2

I've been real pleased with this image, I can read the USB as a user, but still can't write it. I tried: "mount /media -w" after a "umount /media" and have an fstab entry that looks like:"/dev/sda1 /media vfat defaults,rw,user 0 1" although I have no idea what the "defaults" "0" and "1" are for, I w...

Re: Ubuntu / Linaro for Raspberry Pi 2

A little time with google and I found "fdisk -l" which showed that I needed to do the mount on /dev/sda1 and I gave it /media as the directory and there it was. Now to get it to mount automagically and give the user permission to use it.

Re: Ubuntu / Linaro for Raspberry Pi 2

After loading Raspian I loaded Mahjongg and Blender neither of which would start. I burned wintrmutes last image and wonder of wonders both started. My only problem now is I can't get a flash drive to mount. I tried "sudo mount /dev/sda /mnt" and got an error. It just plugged in and worked with Rasp...

Re: bridge shield between Arduino and Raspberry Pi?

The I2C bus on the Raspberry Pi allows you to connect analog to digital converters and a number of other useful devices. I got mine at Adafruit. They also have library routines for Python so you can use the device without investing a great deal of your time.

I would create two images for the sprite, one normal one with the arm up. When you want the arm to go up replace the sprite image.

Re: USB - the Elephant in our Room

If it is a switcher there will be a certain amount of hash. Many of the wall wart types are just poorly rectified transformers, I have seen some with ripple of several volts. The ones with USB connections rated at an amp or better are probably the best bets. The other type is the supplies for the US...

Re: USB - the Elephant in our Room

I think it is important how a supply responds to a fast change in load. That is why some people are putting caps across their supplies, they can't take the transients. The switching two amp supplies that I have are solid enough that I have never had a problem. I know for sure that some of the phone ...

Re: USB - the Elephant in our Room

I received a 2 Amp switching power supply with a Rosewill 7 port hub. The hub didn't work out, but the power supply is great. I use a Kensington 4 port hub with the 2 Amp supply and feed my pi with it as well as hooking up my keyboard, mouse and 16G USB stick. I have never had a power or USB problem...

Re: Raspberry Pi with 512mb RAM in the Wild and Element14...

The last thing I did, was to do an rpi-update, after that no more problems. The old version reads the serial number as a 5 and the new as f. I have read that there are different firmware drivers depending on the memory installed/used. I can run with an old split, just 256M, or with the 512M and one ...

It worked fine until I rebooted it, then it hangs just the same. At least the memory shown in the top command is correct though.
