Re: Set video memory to 0?

You should be greatful with the 240MB, having come from years of optimising my NAS which has only 128MB and running as a web server, minidlna, subversion, samba and countless other things, 240M is like growing a new limb :D

Re: Pi won't boot after update.

Latest github from 21 hours ago boots, using all files from latest github. I take it you managed to solve the issue/ build on a different machine? There was a fix in last start.elf. Not specifically for your problem, I just spotted the wrong caching was being used when loading the kernel. It made n...

Re: Pi won't boot after update.

Yes, there is a version string embedded, so a recompile is not binary identical. So, latest github start.elf fails for you? Should be the same source tree, but they are built on different machines.

Re: Pi won't boot after update.

I want to know the single file change than breaks it. I believe you have said with everything at 0c0 it works. I think I can infer that updating start.elf to the next newer version (790681ab24260d652755901cbe8c5fe59b734b71) breaks it. Can ou confirm that. Also could you try the very latest files. T...

Re: Get GPIO pin value?

Thanks, a little bit of reading did the trick. As an FYI for anyone else having the same problem, it turns out that the "Pin Level" registers work for detecting the level of output pins that you have set, and you can read it's value from there. Is it just me or are there numerous errors in the broad...

Re: Instructions for building XBMC for Raspbian

Actually, it'd make more sense to just have an official build of XBMC in the package repository so anyone with Raspbian can just install it (if they choose) with apt-get. If it is indeed as easy as that, then that would be great... but surely if it was, someone would already have done it by now? As...

Just to point out that the Samsung or Hynix name on the 'SoC' is only on the RAM chip. Directly underneath that is the CPU/GPU which is sole sourced by Broadcom.
