    Wish there was, still working on one for Radxa; Big hang-up @ Rk1000 and HDMI addresses, Omega has a change which is making me and the Kernel buggy. Also compiling from the 3.0.36 may not be possible??? Thinking that 3.0.72 might be better, for having fewer build errors using a 3.0.36 KK kernel which has more updates than a 3.0.36 jb deconfig. Don't know if everyone went to 3.10 or not, so I'll keep trying the 101 and if I succeed I'll share.

      DNSound built a working 3.0.101 Linux kernel for the X7. Maybe it will help you.
      His .config and modded box.c library is attached too

        Thanks--that is where I am now on my build, his .config and modded box will give good direction.

          Hi all,
          does someone know how to build a working kernel with the latest 3.10 sources???
          I don't know where to start and how to modify the dtb to match our pinout (in my case I'm working on my Minix X/) ... Can anyone pls give us some direction or post an how-to guide???
          I'm still stuck @3.0.101, it works fine but i would love to test 3.10 kernel too

            100 % cpu use wifi module

            hi,

            I'm trying to enable wifi on mk908 v3 (6210 wifi & bt combo)... so I updated board-rk3188-box.c pintout definitions to match this model, and wifi gets detected and can connect to my wireless network, but there're some issues:

            - Can't 'modprobe rkwifi' and I neet to 'modprobe wlan' to get modules loaded.

            Code:
            [ 4029.465739] wlan: version magic '3.0.72+ SMP preempt mod_unload ARMv7 ' should be '3.0.101+ SMP preempt mod_unload ARMv7 '

            tried to disable CONFIG_WIFI_CONTROL_FUNC in .config, but gets enabled again so I guess the bcmsdh_probe keeps owned by kernel ¿?...

            - So I modprobe wlan, wlan0 gets detected and associated... but then, a process dhd_dpc, gets 50-60 % cpu time all the time:

              Hi,

              well done; I think you have encountered a big problem, as of now there are still not available sources for the bcm wifi, so you can't load wifi modules from older version of kernl( as I can see ur using the 3.0.72+ modules on this kernel, that's not possible;I'm still connected using a cable,not wifi).I think CONFIG_WIFI_CONTROL_FUNC should be enabled, or eventually when the sources will be released you won't be able to use ur wifi combo chip.Also make sure you have configured the correct pinout for your board( you can take an older working kernel and check them ;D ) .Also check in your .config that all the wireless related components ar compiled as modules or built-in, as I can see ur kernel already handle bcmsdh .

              Hope this will be useful

                hi,Sure you can load kernel modules from other version... the issue seems that is bcm_dhd is integrated on rkwifi module from 3.0.72 and below versions, but it is stand alone in 3.0.101.To compile bdm_dhd as a module uncomment this line @ Rockchip-GPL-Kernel / drivers / net / wireless / rkwifi / bcmdhd / Makefile:#CONFIG_RKWIFI = mthen bdmdhd.ko is generated. If you load this mod and then rkwifi, duplicate symbols... if you load rkwifi alone, no 100% cpu, but wifi does not work ... module toggles power gpio, but sd wifi card is not detected..so maybe rkwifi.ko from 3.0.72 and below simply doesn't work anymore in newer kernels...gmtii.

                  MK808B rk3066 on 3.0.101 from Omegamoon

                  Hey,

                  I run 3.0.101 on my MK808B with MediaTek MT5931 wifi card and Arch Linux ARM distribution. I had to modify 3.0.101 sources a little to be able to run wifi card and change .config a little to reach FullHD resolution. I run Linux from USB hard drive.

                  I still have problems with:
                  - sound doesn't work at all, still fighting
                  - can run xorg but drivers looks crappy, 2D accelerated doesn't work at all (because dedicated driver is tuned for custom 3.0.36+)
                  - zRAM seems to be completely broken in the kernel

                    3.0.101 zRAM stack trace

                    zRAM is broken, I'm getting Segmentation Fault and stack trace from the kernel when trying to use it. Device is created, I can write size to /dev/block/zram0/disksize but when trying to initialize fs on zram it throws a stacktrace:

                      Hey,

                      I run 3.0.101 on my MK808B with MediaTek MT5931 wifi card and Arch Linux ARM distribution. I had to modify 3.0.101 sources a little to be able to run wifi card and change .config a little to reach FullHD resolution. I run Linux from USB hard drive.

                      I still have problems with:
                      - sound doesn't work at all, still fighting
                      - can run xorg but drivers looks crappy, 2D accelerated doesn't work at all (because dedicated driver is tuned for custom 3.0.36+)
                      - zRAM seems to be completely broken in the kernel

                      I'm trying to compile 3.0.101 kernel for linux and a similar device (in my case for mk808b with mediatek combo MT5931+MT6320 wifi/bt) Could you post the patches and your config, please? Problems I have when cross compiling are related mainly to the combo device and GPIOs, so at least having a reference about these would be very helpful.
