ARM – Odroid U2 – 3.17 Boot, but no USB..

Tried the latest 3.17 kernel with my Odroid U2, and managed to get it to boot successfully, but USB still doesn’t work, which is a show-stopper, as the Ethernet adapter is a USB-connected device..

Start with # make exynos_defconfig, and then select arch/arm/boot/dts/exynos4412-odroidu3.dtb when merging with zImage, etc…

As this is standard code now, the fix should be easier to investigate, given time.!

ARM – CuBox to Kernel 3.17..

Just installed Kernel 3.17 ‘Final’ on the CuBox I4-Pro..    Source code from

Fedora release 20 (Heisenbug)
Kernel 3.17.0 on an armv7l (ttymxc0)
$ uname -a
Linux rgcubox 3.17.0 #1 SMP PREEMPT Mon Oct 6 14:01:51 EDT 2014 armv7l armv7l armv7l GNU/Linux

Kernel 3.17 – At Last…

Kernel 3.17 Final has – finally – been released, and details are here:

As with the last -rc, the latest NVIDIA (340.46) and VMware (10.0.3 patched) drivers install and run OK..

$ uname -a
Linux rglinux-i7 3.17.0 #1 SMP PREEMPT Sun Oct 5 18:02:39 PDT 2014 x86_64 x86_64 x86_64 GNU/Linux

Kernel 3.17-rc7 – Unexpected..

Kernel 3.17 was due out by now, but we have another release candidate instead - rc7..

No problems with the latest VMware (10.0.3 patched) and NVIDIA (340.32) drivers, which compile and load OK..   The latest NVIDIA ‘beta’ (343.22) compiles/loads OK, but I need to test it more thoroughly with VMware, as the previous version broke the VM display on my main system..

# uname -a
Linux rg6830l 3.17.0-rc7 #1 SMP PREEMPT Mon Sep 29 10:36:46 PDT 2014 x86_64 x86_64 x86_64 GNU/Linux

Details – and an explanation for the delay – are here:

Kernel 3.17-rc6 – 3.17 Final Soon?

Installed Kernel 3.17-rc6, and – as with -rc5 – the latest VMware (10.0.3 with vmnet patch) and NVIDIA (340.32) drivers compile and install/load OK..

# uname -a
Linux rg6830l 3.17.0-rc6 #1 SMP PREEMPT Mon Sep 22 09:48:38 PDT 2014 x86_64 x86_64 x86_64 GNU/Linux

Details are here:

From the comments, it seems that the next release may be 3.17 Final..

Kernel 3.17-rc5 – Same Comments as -rc4..

Just updated the test system to Kernel 3.17-rc5, and – as with -rc4 – the vmnet-patched VMware 10.0.3 and NVIDIA 340.32 both compile/load OK..

$ uname -a
Linux rg6830l 3.17.0-rc5 #1 SMP PREEMPT Sun Sep 14 23:17:13 PDT 2014 x86_64 x86_64 x86_64 GNU/Linux

ARM – Odroid U2 – Finally an Up-to-Date Kernel?

I had been frustrated by the apparent inability of the suppliers to provide anything other than an obsolete Ubuntu-centric 3.8+ kernel for the Odroid U2, and other kernels I had tested were somewhat ‘incomplete’…

I finally managed to get a 3.17-r3 version from

This now includes the necessary ‘bits’ for the U3, which is functionally identical to the U2…   After some minor config changes – including de-selecting some of the mali options, as some header files were missing/obsolete – I managed to get it to boot on my Odroid U2:

Fedora release 20 (Heisenbug)
Kernel 3.17.0-rc3 on an armv7l (ttySAC1)
# uname -a
Linux rgodroid 3.17.0-rc3 #4 SMP PREEMPT Thu Sep 11 02:42:18 BST 2014 armv7l armv7l armv7l GNU/Linux

Unfortunately, further testing was impossible, after a sudden – and catastrophic – USB stick failure, which trashed the root filesystem..

More testing will follow, when that is replaced!

Kernel 3.17-rc4 – OK with (Patched) VMware, and latest NVIDIA..

Updated to Kernel 3.17-rc4, and the vmnet-patched VMware (10.0.3) and latest NVIDIA (340.32) all compile/load OK..    See previous -rc3 article for details of the patch..

$ uname -a 
Linux rg6830l 3.17.0-rc4 #1 SMP PREEMPT Sun Sep 7 22:33:23 PDT 2014 x86_64 x86_64 x86_64 GNU/Linux

Kernel 3.17-rc3 – Breaks VMNET – and a Fix..

Just tested Kernel 3.17-rc3, and it breaks VMware (10.0.3) – vmnet:

/tmp/modconfig-d0zqLW/vmnet-only/netif.c: In function ‘VNetNetIf_Create’:
/tmp/modconfig-d0zqLW/vmnet-only/netif.c:152:64: error: macro "alloc_netdev" requires 4 arguments, but only 3 given
    dev = alloc_netdev(sizeof *netIf, deviceName, VNetNetIfSetup);
/tmp/modconfig-d0zqLW/vmnet-only/netif.c:152:10: error: ‘alloc_netdev’ undeclared (first use in this function)
    dev = alloc_netdev(sizeof *netIf, deviceName, VNetNetIfSetup);

Thanks to Erwin Zoer (see his comment below the earlier post for 3.17-rc1..), there is a fix available – for ~/vmware-only/netif.c

For kernel 3.17-rc3 and later, change line 152 from

dev = alloc_netdev(sizeof *netIf, deviceName, VNetNetIfSetup);
dev = alloc_netdev(sizeof *netIf, deviceName, NET_NAME_UNKNOWN, VNetNetIfSetup);

Then re-TAR etc.. and re-run the VMware compile/install:

# vmware-modconfig --console --install-all

I have applied this on my test system, and it works OK..

ARM – CuBox to 3.17-rc2 – 23rd Anniversary Release..

Just updated the CuBox i4-Pro to Kernel 3.17-rc2, which was – deliberately – released on the 23rd anniversary of the initial release of kernel code for ‘Linux’..
