Memory Loss

I’ve lost my memory – not me exactly but my Raspberry Pi. Since upgrading to the latest development release, 5.21 dated 03-Jun-14 I have 128Mb free rather than the 448Mb I had previously. How do I get it back again?

It should be configurable in !Boot.Loader.CONFIG/TXT (you enter the amount to allocate to the GPU so you’ll want to set it to 64).

Having said that, I saw something in the Raspbian release notes a couple of days ago about the memory allocations moving to a different file. I haven’t looked into this any further yet (and therefore don’t know whether it’s Raspbian-specific), but did you change the Pi firmware or just the OS ROM?

64.

I wonder if something has changed in the Firmware.

I updated the Firmware, OS ROM and associated HardDisc image. Too much in one go I suspect.

Thanks for the hint – perhaps a bit more digging is required.

Problem is the Firmware. I used the latest firmware from…

https://github.com.raspberrypi/firmware/tree/master/boot

I think I read somewhere that these releases might cause problems. Have re-installed original Firmware (Bootcode/bin, Fixup/dat and Start/Elf) and now correct memory has been restored.
Thanks for the pointers.

URL wrong sorry… should be
