Re: PoE HAT - USB Ports not working - over-current

I have seen an interesting issue that no one here seems to have mentioned thus far. I had two HATs with apparently distant batch numbers. I connected them to my Ubiquiti PoE switch with a ~30cm ethernet cable (amongst others, for testing) and yes they exhibited the USB issues. Both with and without ...

Re: Who's got their hands on a B+ so far?

Finally got high current mode to work on my Pi. I had to use the "old" style gpio safe mode flag even though I'm running the latest firmware. For some reason my config.txt is getting wiped on a reboot, and if I try to modify it from the running Pi I get an I/O error on save. I'm hoping it's just a d...

Aha. So that's how we get the extra current. I managed to get a freebie from Element 14 at Tower Bridge, took it straight home to see if I could ditch the spliced cable and powered hub I'm using for the B, but alas it would not run my 2.5" HDD.

Re: Pi B+ ID_SD and ID_SC

If this is correct, it's going to be great, the pi will be able to swap drivers and pin settings by identifying the board attached through its ID chip. This should allow the GPIO to detect which device has been attached like a USB port does. I'm hoping this will happen very early in the boot process...

Re: Pi won't boot after update.

I never managed to solve the problem completely as I RMA'd the device, my suggestion would be to contact Farnell and have them send you a new board, the new board should not suffer the issue (as my new board does not).

Re: XBian - Small, Fast, Lightweight XBMC solution

it's the same in xbian and others but someone from the xbian team said that the cpu load shown in xbmc is little off. Try checking it with top when you are logged through ssh. I think that a part of the cpu is busy rendering the meter and that's why it's ~80%. However I remember maybe incorrectly t...

Re: XBian - Small, Fast, Lightweight XBMC solution

I'm looking to replace my Raspbian + XBMC with A pre-built XBMC image, because I can't get the CPU idle to drop below 40% in XBMC, how does it run with this build?

This seems like the best option if it works cause I want a standard desktop but XBMC too.

Video playback issues with XBMC on Raspbian.

I had a 256MB Pi before it broke and I had to send it back. Back then, I had XBMC running on Raspbian that I had built myself, and it would play my entire library on my media server. Having gotten my new Pi, I promptly installed Raspbian again and downloaded one of the pre-built XBMC packages and in...

You could try this build: https://dl.dropbox.com/u/3669512/temp/start.elf Basically top of tree with a new config option max_pll_freq. The default is 2400 (MHz) which should behave the same as latest start.elf. If you set it to: max_pll_freq=1000 then you should get the same pll as the older 0c0ef ...
