Finally managed to cobble together a rudimentary case and fan with heatsink for the rock2, and now I can compile correctly (# make -j5, etc..) and run # git clone… without the system overheating and rebooting.. Just two sheets of perspex, and some assorted m3 nylon pillars and screws.. The 5V power supply needs to be around … Continue reading →
Kernel 4.5-rc7 had booted successfully on the Radxa Rock2, but 4.5 Final failed, as the SDcard was ‘loaded’ just too late: mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0) dwmmc_rockchip ff0f0000.dwmmc: 1 slots initialized ……………………… VFS: Cannot open root device “mmcblk1p1” or unknown-block(0,0): error -6 ………………………… Kernel panic – … Continue reading →
After a lot of testing, and some more confusion, I have managed to get the Rock2 to boot using the latest (2016.03-rc3) version of U-Boot, and the latest kernel (4.5-rc7) As previously, there was a lot of conflicting information……. I started by booting into the semi-proprietary 3.10-based kernel on the SDcard, and then erasing the eMMC (dd … Continue reading →
Recently took delivery of a Radxa Rock2 ARMv7 system, based on the RX3288 Cortex A17 chipset.. The system comes with a version of Android installed on the onboard eMMC, but I managed – after a bit of work – to install Fedora 23 on an SDcard and get it to boot onto that.. At this point, I … Continue reading →
I recently acquired a vintage (2006?) Minolta Elite 5400 II scanner, and – according to the VueScan support info, I needed to ”set up libusb device protections”.. That info included a link to a somewhat ancient SANE USB support page – last changed in 2003!.. That rang a bell, and I guessed that I had to mess … Continue reading →
I have just posted copies of recent kernel configs for the Odroid U3 and CuBox-i4Pro.. Odroid U3 – Kernel config for 4.4 : http://pastebin.com/NveRajaZ CuBox-i4Pro – Kernel config for 4.4.1: http://pastebin.com/Kbexi0A5 These do not include working WiFi, as 2.4GHz is pretty useless at my location… Robert Gadsdon.

I did a clean install of Fedora 23 on my new ‘built from recycled components‘ crash-and-burn test system recently, and all went reasonably well – apart from – apparently – having to re-partition an already-partitioned drive (!)… After booting for the first time, I found that a ‘bridged’ network link – virtbr0 – was active.. As I … Continue reading →
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 →
Just got a ‘BananaPro‘ ARMv7 board, and updated it to Kernel 4.4-rc4 (from kernel.org) and Fedora 23. More details are here: http://linux-sunxi.org/LeMaker_Banana_Pro I compiled U-Boot from the latest (2015.10) released version, from ftp.denx.de/pub/u-boot/ : # cd u-boot # make Bananapro_defconfig # make ARCH=arm CROSS_COMPILE=arm-linux-gnu- (or whatever cross-compiler you are using) Then as root, copy to the SDCard … Continue reading →
