whoman Posted January 23, 2017 Share Posted January 23, 2017 Hello All! Just got my MINI M8S today and thanks to Armbian, I now have Debian up and running. I used "Armbian_5.24_Amlogic-s905x_Debian_jessie_3.14.29_20170118.img" The only issue I have is that some of the ALSA kernel modules that are needed for MIDI support are disabled in this kernel. Specifically, SND_SEQ_OSS, and possibly one or two others. So I went ahead and installed the "linux-source" package, which matched up nicely with the existing headers. After uncompressing, I copied "cp ../linux-headers-3.14.29/Module.symvers .", then I ran 'make menuconfig', which pulled in the config from '/boot' and I proceeded to enable the pertinent module options within menuconfig, however 'OSS Sequencer API' isn't module capable (you can only put an asterisk in the box, not an M). So I proceeded to compile a new kernel with "make-kpkg clean" followed by "fakeroot make-kpkg --initrd --revision=custom.1.0 kernel_image". Oddly enough I got a message suggesting the "revision" parameter had an illegal character (which it does not). # fakeroot make-kpkg --initrd --revision=custom.1.0 kernel_image Error: The revision string may only contain alphanumerics and the characters ~ + . If epochs are used, the colon : is also allowed The current value is: custom.1.0 Aborting. So I removed the 'revision' parameter completely, and ran "make-kpkg clean" followed by "fakeroot make-kpkg --initrd kernel_image" fakeroot make-kpkg --initrd kernel_imageexec make kpkg_version=13.014+nmu1 -f /usr/share/kernel-package/ruleset/minimal.mk debian INITRD=YES====== making target debian/stamp/conf/minimal_debian [new prereqs: ]======This is kernel package version 13.014+nmu1.test -d debian || mkdir debiantest ! -e stamp-building || rm -f stamp-buildinginstall -p -m 755 /usr/share/kernel-package/rules debian/rulesfor file in ChangeLog Control Control.bin86 config templates.in rules; do \ cp -f /usr/share/kernel-package/$file ./debian/; \ donecp: cannot stat ‘/usr/share/kernel-package/ChangeLog’: No such file or directoryfor dir in Config docs examples ruleset scripts pkg po; do \ cp -af /usr/share/kernel-package/$dir ./debian/; \ donetest -f debian/control || sed -e 's/=V/3.16.39/g' \ -e 's/=D/3.16.39-10.00.Custom/g' -e 's/=A/arm64/g' \ -e 's/=SA//g' \ -e 's/=I//g' \ -e 's/=CV/3.16/g' \ -e 's/=M/Unknown Kernel Package Maintainer <unknown@unconfigured.in.etc.kernel-pkg.conf>/g' \ -e 's/=ST/linux/g' -e 's/=B/arm64/g' \ -e 's/=R//g' /usr/share/kernel-package/Control > debian/controltest -f debian/changelog || sed -e 's/=V/3.16.39/g' \ -e 's/=D/3.16.39-10.00.Custom/g' -e 's/=A/arm64/g' \ -e 's/=ST/linux/g' -e 's/=B/arm64/g' \ -e 's/=M/Unknown Kernel Package Maintainer <unknown@unconfigured.in.etc.kernel-pkg.conf>/g' \ /usr/share/kernel-package/changelog > debian/changelogchmod 0644 debian/control debian/changelogtest -d ./debian/stamp || mkdir debian/stampmake -f debian/rules debian/stamp/conf/kernel-confmake[1]: Entering directory '/usr/src/linux-source-3.16'debian/ruleset/misc/checks.mk:36: *** Error.

balbes150 Posted January 24, 2017 Share Posted January 24, 2017 To build your kernel you can use a different algorithm of actions. Clone the source code. Copy the working configuration. To make a change. To compile the kernel. To collect the initrd. To handle initrd mkimage utility (need it for work u-boot). Without treatment, the initrd will not be perceived by the boot loader.

whoman Posted January 24, 2017 Author Share Posted January 24, 2017 Hi Balbes150, Thank you for your response. I will try how you suggest. I think perhaps for the step "Clone the source code" might be my mistake... I used "apt-get install linux-source". This time I will try cloning the source directly from "kernel.org". I will check to make sure I download the correct version. I will try this tonight. Thanks again. Link to comment Share on other sites More sharing options...
balbes150 Posted January 24, 2017 Share Posted January 24, 2017 The kernel version with kernel.org will not work without patch. I recommend to use the source codes that are used to determine the kernel in the image. Link to comment Share on other sites More sharing options...
whoman Posted January 27, 2017 Author Share Posted January 27, 2017 I'm not sure which location to download the source for my kernel image. I originally downloaded the image "Armbian_5.24_Amlogic-s905x_Debian_jessie_3.14.29_20170118.img" from the link: https://yadi.sk/d/pHxaRAs-tZiei I can't seem to determine where the source code is located. I did go to https://github.com/igorpecovnik/lib on my Ubuntu Desktop system and I did run the compile.sh script. I see that there is a kernel source folder named "sources/linux-odroidc2/odroidc2-3.14.y" Would this be the source used to compile my kernel from "Armbian_5.24_Amlogic-s905x_Debian_jessie_3.14.29_20170118.img"? If that is incorrect, can you let me know where I could find the source for "Armbian_5.24_Amlogic-s905x_Debian_jessie_3.14.29_20170118.img"? Thanks for your time.

balbes150 Posted January 27, 2017 Share Posted January 27, 2017 The kernel sources for S905\S905X\S912 are in this GIT. The compliance branch in GIT the names of images and kernel versions. 1. images, the title of which stated "3.14.29" use - collected from branches S905X (universal - for the entire line of chips S9xxx). 2. Images - "3.14.79" - the branch odroid (this thread is only for chips S905) 3. Branch "armbian" - universal plan - for entire line S9xxx in an attempt to collect all positive elements branches (Amlogic + Hardkernel + LE). Pay attention to Assembly and installation\kernel for TV boxes is specific and different from the usual. I hope Marc (user Nofan Tasi) to share its successful experience build the kernel from source for TV boxes (including their details). 1 Link to comment Share on other sites More sharing options...

whoman Posted January 28, 2017 Author Share Posted January 28, 2017 Thank you so much, I followed Nofan Tasi's Recipe and it worked perfectly. I was able to successfully compile the new kernel with the modules I wanted to enable... I then modified my boot configuration to boot the new kernel, and confirmed now the modules are loading and MIDI is working correctly. Thanks again Nofan Tasi and Balbes150. Now I have some gstreamer questions I will open a new thread for. Link to comment Share on other sites More sharing options...
dxs1 Posted January 28, 2017 Share Posted January 28, 2017 Hi , My device is a "MINI M8S II" and I am using "Armbian_5.24_Amlogic-s905x_Ubuntu_xenial_3.14.29_desktop_20170118.img". I have no audio output on HDMI. I am open to use "Armbian_5.24_Amlogic-s905x_Debian_jessie_3.14.29_20170118.img" if the issue can be solved By any chance, can you share your new kernel for download with the modules enabled for this device ? Thank you. Link to comment Share on other sites More sharing options...
whoman Posted January 28, 2017 Author Share Posted January 28, 2017 Hi dxs1, Unfortunately my kernel will do nothing different for audio output. the modules I have compiled are only for "midi sequencer" communication. They have nothing to do with audio output. Also, I could be mistaken but I'm pretty sure the amlogic drivers for sound output are already in the original kernel configuration, so that is likely not the cause of your issue. I'm personally using this strictly for video/image output, so I have no experience with audio output on the S905X. I would suggest creating a new thread, so that more people will see your thread title and can help with your problem. 1 Link to comment Share on other sites More sharing options...

The problem is that the kernel does not support midi. (/dev/snd/seq not found) I am an end user, so it's hard to get a kernel file. I tried to follow the example of Nofan Tasi and it was not successful. As I said, I'm not expert and do not understand the config values of kernel. Can you describe your kernel compilation successfully? Hope to receive your kindness from you. Thank you Link to comment Share on other sites More sharing options...
