Re: PI Zero W - no bluetooth device found in raspbian

Raspbian sort of works. Can you elaborate what you mean by that ? I tried 2015-11-21-raspbian-jessie, but kernel hangs during boot: [ 5.554717] devtmpfs: mounted [ 5.584176] Freeing unused kernel memory: 420K (80779000 - 807e2000) [ 6.796329] random: systemd urandom read with 7 bits of entropy avai...

Re: QEMU patches for RPi emulation - Initial release

There is problem with kernel in latest Raspbian `2014-12-24`. It displays "Uncompressing Linux... done, booting the kernel." and nothing more. Version `2014-09-09` works fine with the same parameters: qemu-system-arm -kernel xecdesign_demo/kernel-2014-12-24-wheezy -cpu arm1176 -m 512 -M raspi -seria...
