Guest david_dawkins Posted January 31, 2010 Report Share Posted January 31, 2010 Hey guys I think I'm going to make a tutorial on how to edit the android kernel if I can manage to compile my one. There aren't any tutorials on the net... BTW I started again from the beginning - I now only copied the drivers (instead of the drivers and the mach_msm directory). I guess that won't work as there is still some HTC stuff in the kernel... like HTC_battery and things like that... I'll try it anyway. Stay Tuned! Greetings, BigBearMDC Now that would be excellent. +1 vote for the tutorial Mr Bear Link to comment Share on other sites More sharing options...
Guest Bakes Posted January 31, 2010 Report Share Posted January 31, 2010 Don't start thinking about the tutorial until you have it working yourself; anyone familiar with C or the like will probably be able to bash through kernel editing, but you are trying to help all of us so having a working product is more interesting for us :) Link to comment Share on other sites More sharing options...

I think you're underestimating the amount of work this takes. I've plenty (years) of development experience, but this isn't a language problem, it's what to edit/configure and why. I can't help until someone shows me what to do. Link to comment Share on other sites More sharing options...
Guest BigBearMDC Posted January 31, 2010 Report Share Posted January 31, 2010 I would make the tutorial after i finished this project so you guys don't need to worry about that - except you're interseted in the tutorial :) Greetings, BigBearMDC Link to comment Share on other sites More sharing options...

I can't help until someone shows me what to do. Having worked on similar projects before (a while back), it's more like 'give a man a kernel source, that man must wait for kernel drivers; teach a man how to build a kernel, everything gets very fragmented and very confusing very quickly unless they are in constant contact and are using the same code sources.' If there isn't a proper version control system for checking in and checking out code, no one will get very far at all because people (or the original coder) will make changes that will eventually become incompatible with each other. That's why BigBear's had to start from scratch so many times, and why the other threads have just fragmented into different people not going very far at all.

Guest BigBearMDC Posted January 31, 2010 Report Share Posted January 31, 2010 UPDATE: Wohoo :) This is the first time the compiler went through ".tmp_vmlinux1" without telling me "no machine record defined"!! Allthough I did not finish to compile the kernel, this is a major breakthrough! Stay Tuned! Greetings, BigBearMDC Link to comment Share on other sites More sharing options...

Guest BigBearMDC Posted February 2, 2010 Report Share Posted February 2, 2010 Is someone willing to help me? I'd upload my modified kernel source so somebody can help me porting the kernel. It's really difficult to find some functions in header files... I now also made a Logfile in which I noticed the files i edited. Just post a reply if youre interested :) Greetings, BigBearMDC Link to comment Share on other sites More sharing options...
Guest BigBearMDC Posted February 2, 2010 Report Share Posted February 2, 2010 (edited) For everyone whos interested in it: download me :) EDIT: Everyone who takes a look at the Compiling_LOG file might realize how difficult it is to find all the needed header files and to edit them correctly.

Greetings, BigBearMDC OK, I'm looking at that very first error (linux/mem_notify.h missing). Did the original Hero kernel compile cleanly? If so, where did drivers/char/mem.c come from? I'm assuming it was added as part of your edits. Sorry if I'm being thick. The source tree you posted is downloading right now. Dave Link to comment Share on other sites More sharing options...
Guest BigBearMDC Posted February 2, 2010 Report Share Posted February 2, 2010 The original Hero kernel compiled without any problems. No, mem.c is part of the Hero kernel as well. You should be able to continue compiling from exactly the same point were I'm at the moment. Thanks for your help, Dave!

So your edits have either changed the INCLUDE path, or have removed the headers it's looking for. I'm guessing it's the INCLUDE path, since why would you remove the headers? Download failed, I need to kick it off again. Edited February 2, 2010 by david_dawkins Link to comment Share on other sites More sharing options...
Guest BigBearMDC Posted February 3, 2010 Report Share Posted February 3, 2010 Hi Dave! Well the mem.c from the Pulse has just more functions that need extra headerfiles, which are not needed in the Hero kernel. I just copied the drivers from the Pulse kernel into the Hero kernel => /Pulse_kernel/drivers to /Hero_kernel/drivers. Thats why there are missing header files. I tried to change only the necessary parts of the kernel - only the drivers. But the problem is, that the Pulse drivers are far more "integrated" into the kernel as they include more headerfiles than the Hero kernel does. So it's difficult to find all the header files that are nedded for the drivers to work properly. I ned to open every source file that causes an error, open every header file that is included, open most of the header files that are included in those header files and compare them with the files from the Pulse kernel. That was not that much work in most cases - but if it gets more difficult it takes me almost an hour to find the problem. And that only for one file... But it works. BTW at the end of the LOG file you can have a look at the problems I'm facing now. I almost searched 2 or 3 hours, but couldn't find anything...

Guest david_dawkins Posted February 3, 2010 Report Share Posted February 3, 2010 OK, I understand. My download completed and I can open it up. I had to trash my Ubuntu though, since I'd used Wubi (very cool) and it had installed the newer Ubuntu. I read that we need a slightly older version so the cross-compilation toolchain works. Can you do a "uname -a" for me, or point me at the Ubuntu you have installed? Thanks! Dave Link to comment Share on other sites More sharing options...
Guest BigBearMDC Posted February 3, 2010 Report Share Posted February 3, 2010 (edited) Linux Android-DEV-PC 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux ;) I'm currently working with the 4.3.1 toolchain and it works fine. I now found a way to search for the headerfiles that contain the functions i need: ~/kernel/kernel_pulse$ grep -rl 'function_name' * | grep .h That works pretty good.

Guest BigBearMDC Posted February 10, 2010 Report Share Posted February 10, 2010 Hey guys. Just to keep you updated: David Dawkins now helps me a lot. We tried to compile the Hero kernel with the drivers from the Pulse. But then Dave realised that there is really much hardware specific stuff in the mach-msm dir of the kernel. So we decited to copy the mach-msm dir too. Then Dave had another idea. We want to try to compile android with the already compiled libs from the Hero ROM, so that we can use the libs from the Hero ROM, which are responsible for flash - at least we think that. So what we're doing at the moment: - compile the Hero kernel with the drivers and mach-msm dir from the Pulse kernel. - compile android with the Hero libs. Stay Tuned!

Guest shovon Posted February 11, 2010 Report Share Posted February 11, 2010 (edited) Looks like we'll be needing Android 2.1 for flash :D Flash for Android coming soon If we have to wait for an official release ;) Edited February 11, 2010 by shovon Link to comment Share on other sites More sharing options...
Guest BigBearMDC Posted February 11, 2010 Report Share Posted February 11, 2010 For flash 10.1, we'd need android 2.1. But not for the flash player that works on the Hero (i think its FlashPlayer 8 ) ;) Greetings, BigBear Link to comment Share on other sites More sharing options...
Guest CHN-michael Posted March 10, 2010 Report Share Posted March 10, 2010 My Friends told us about their project based on the Flash on Android 1.5,But it seemd faild on my pulse,just play a well perfomace on his ARM band,sc34XX. Link to comment Share on other sites More sharing options...

Guest screwface Posted March 10, 2010 Report Share Posted March 10, 2010 wait for a Motorola CLIQ XT rom dump. It's a stock android 1.5 device with flash light. Will be easier than porting it from the hero. Link to comment Share on other sites More sharing options...
