After a lot of searching – and more testing (mostly unsuccessful..) I finally have a set of two patches that fix the Ethernet driver problem with the Rock2 in 4.6-rc1.. The problem is that the stmmac driver is common to several SOC setups, and each maintainer seems to have produced their own version of a fix.. The … Continue reading →

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 →

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 →
