ARM – Pi2 – Kernel 4.4-rc5 – U-Boot Fail, and Workaround..

Adventures With Linux ™ Posted on December 20, 2015 by RGDecember 20, 2015

Recently attempted to update the Pi2 to Kernel 4.4-rc5, and encountered a problem.. The more recent proprietary Raspberry Pi 2 kernels have switched to using ‘DTB Overlays’ to control various components, but these are – currently – unsupported by U-Boot.. Booting the kernel with U-Boot results in mmc errors, and register dump: ……………….. timeout waiting for hardware … Continue reading →

ARM – Pi to 4.0.. Patience is a Virtue..?

Adventures With Linux ™ Posted on April 14, 2015 by RGApril 14, 2015

Tried updating the Raspberry Pi-s (Classic model B and Pi2) to Kernel 4.0, from https://github.com/raspberrypi/linux/tree/rpi-4.0.y, and my first attempt was – it seems – too soon, as the Classic Pi (armv6) failed to boot at all, and the Pi2 (armv7) only booted as far as: …………. bcm2708_dma: DMA manager at f3007000 bcm2708_gpio: bcm2708_gpio_probe 80625490 vc-mem: phys_addr:0x00000000 mem_base=0x3dc00000 … Continue reading →

ARM – Raspberry Pi and Pi2 – Trials with Later Kernels..

Adventures With Linux ™ Posted on March 23, 2015 by RGMarch 23, 2015

I had Kernel 3.19.0 (originally from https://github.com/raspberrypi/linux/tree/rpi-3.19.y – now updated) running on my Pi (armv6) and Pi2 (armv7) with no problems (apart from the Pi2 seeming very sluggish..) but after that had a few ‘issues’.. Pi:  Kernel 3.19.1 OK, but 3.19.2 refused to boot (nothing on console) Pi2:  Kernel 3.19.1 booted and then crashed: BCM2708FB: allocated DMA … Continue reading →

ARM – Raspberry Pi 2 – Kernel Compile..

Adventures With Linux ™ Posted on February 19, 2015 by RGFebruary 19, 2015

Finally got the Raspberry Pi 2, and installed Fedora 21 (armv7hl) with no problems..    Temporarily used object code 3.18.7-v7+ from the repository, and then tested kernel compile options.. The system seems (so far..) to be relatively sluggish compared to my other quad-core armv7 systems..   Compiling on the Pi 2 itself seemed relatively slow, but at least it … Continue reading →

ARM – New Raspberry Pi 2 – ARMv7 at Last..

Adventures With Linux ™ Posted on February 2, 2015 by RGFebruary 2, 2015

For those who have a new Raspberry Pi 2 on order – as I have – the kernel source is now available, at https://github.com/raspberrypi/linux/tree/rpi-3.18.y-rebase. To get the correct config, start with # make bcm2709_defconfig For me, one of the additional benefits is that it is ARMv7, which should support the standard up-to-date Fedora 21 distro, instead of … Continue reading →
