Updated the CuBox-I4Pro to Kernel 4.0-rc4 – from kernel.org, and – at last – networking works without the need for the mach-imx6q.c patch.

Updated the Cubox-i4Pro to Kernel 4.0-rc3, and still needed to apply the one-line patch to linux/arch/arm/mach-imx/mach-imx6q.c, to get networking to work.. http://rglinuxtech.com/?p=1338 Fedora release 22 (Twenty Two) Kernel 4.0.0-rc3 on an armv7l (ttymxc0) ………… ]# uname -a Linux rgcubox 4.0.0-rc3 #3 SMP Mon Mar 9 20:19:45 EDT 2015 armv7l armv7l armv7l GNU/Linux The DreamPlug was OK, and … Continue reading →
Updated the CuBox-i4Pro and DreamPlug to Kernel 4.0-rc2.. No problems with the DreamPlug, and the CuBox just needed the same small patch as for -rc1.. http://rglinuxtech.com/?p=1338 CuBox-i4Pro: Fedora release 22 (Twenty Two) Kernel 4.0.0-rc2 on an armv7l (ttymxc0) ……………. ]# uname -a Linux rgcubox 4.0.0-rc2 #1 SMP Tue Mar 3 21:35:27 EST 2015 armv7l armv7l armv7l GNU/Linux … Continue reading →
The CuBox-i4 Pro booted Kernel 4.0-rc1 OK, but – although eth0 was present – there was no network connection possible.. I found a similar problem described on the Linux Arm Kernel mailing list: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-February/325249.html According to the info there, I changed linux/arch/arm/mach-imx/mach-imx6q.c as follows: Around line 214, change clksel = ptp_clk == enet_ref ? IMX6Q_GPR1_ENET_CLK_SEL_ANATOP : IMX6Q_GPR1_ENET_CLK_SEL_PAD; … Continue reading →
Tried Kernel 4.0-rc1 on the CuBox-i4 Pro (from kernel.org) and the Odroid U3 (from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-4.0.y), and the results are a bit of a mixed bag.. The CuBox boots OK, but – although eth0 appears to be present – networking doesn’t work.. Fedora release 22 (Twenty Two) Kernel 4.0.0-rc1 on an armv7l (ttymxc0) …………….

Updated the test system to Kernel 3.19-rc3, and there is still no fix for VMware (11.0) and the latest NVIDIA (340.65 and 346.22) drivers… The NVIDIA problem will involve getting around a GPL-incompatible module issue.. FATAL: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol ‘__cachemode2pte_tbl’ 3.19-rc3 installs and runs OK on the CuBox-i4 Pro: $ uname -a Linux … Continue reading →
Updated the test (Intel) system, and the Cubox-i4 Pro to Kernel 3.19-rc2.. NVIDIA and VMware still do not compile (see 3.19-rc1 article for details http://rglinuxtech.com/?p=1258) and – so far – there does not seem to be a patch for either. The NVIDIA GPL code incompatibility issue may be more convoluted to fix ‘legally’.. I tried more code … Continue reading →
Just updated the Cubox-i4Pro to 3.19-rc1, after disabling the kernel options for ‘power management’, as the current patch does not compile cleanly..

Updated the CuBox-i4 Pro to Kernel 3.18, and now use the complete ‘device tree’ zImage and dtb boot method: The source can be found here: https://github.com/jmontleon/fedora-20-cubox-i_hb/tree/3.18.0 – and the u-boot boot commands are: setenv bootargs “root=/dev/mmcblk0p3 rootfstype=ext4 rootwait console=ttymxc0,115200n8 console=tty1 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32” setenv bootcmd “load mmc 0:1 0x10800000 zImage; load mmc 0:1 0x18000000 imx6q-cubox-i.dtb; bootz 0x10800000 – 0x18000000” … Continue reading →
