Posted: Mon Feb 27, 2017 9:05 pm Post subject: Kernel sources for Banana Pi |
|
|
Hi,
Months ago I installed a raspberry PI and used https://github.com/raspberrypi/linux
Anyone knows about similar git repository for Banana Pi kernel sources?
Thank you! _________________ Powered by Gentoo Linux since 2003 |

Raspberry sources in gentoo repository comes with a config for banana pi too.
You can run regular make-arm7-blabla-bla-something to autoconfigure it for any of quite a lot of boards. You will get a working kernel and DTB for your piece of hardware.
Perhaps you could also find those defconfigs in other *-sources from portage. I was going to build gentoo-sources for banana, but I got busy with other matters so this idea is waiting for better time to get some attention again.
Anyway, I don't know about git, but you _can_ build a working banana kernel yourself using crossdev and sources from portage. No manual configuration required. |

There are a lot of board sold under the name banana pi, but probably all use the AllWinner Soc,you should be more specific to get more help ...
Try this wiki from the developers of the kernel for AllWinner SoC:

Well,
I managed to install the OS thanks to this: https://wiki.gentoo.org/wiki/Banana_Pi_the_Gentoo_Way
Then I emerged gentoo-sources from the Banana Pi and tried to compile the kernel but I got the error below:
Code: |
CC arch/arm/kernel/psci.o
arch/arm/kernel/psci.c:287:12: error: redefinition of ‘psci_init’
int __init psci_init(void)
^
In file included from arch/arm/kernel/psci.c:26:0:
./arch/arm/include/asm/psci.h:44:19: note: previous definition of ‘psci_init’ was here
static inline int psci_init(void) { return 0; }
^

Makefile:948: recipe for target 'arch/arm/kernel' failed
make: *** [arch/arm/kernel] Error 2

Maybe I should give a try to this: https://wiki.gentoo.org/wiki/Banana_Pi_the_Gentoo_Way#Compile_the_Kernel
What you say szatox is that I should emerge sys-kernel/raspberrypi-sources and try to compile kernel from there?

Yup. It "just worked"™ for me so it's certainly worth a shot.
I remember there were autoconfigs for banana pro and banana pi among many others. "find ./arch/ -iname '*ana*fconfig'" should give you a hint on the correct replacement to be made in "make defconfig" command. Obviously, use make's counterpart from crossdev.
Unfortunately there isn't much more for me to share on this matter, I've only spent a few days on it - mostly playing in different area. |

mamac,
Cross compiling a kernel for a Raspberry Pi is covered in some detail in Raspberry Pi 3 64 bit Install
You will need to change the tuple when you use crossdev to build your cross compiler. I think you have an arm7a, so it will be armv7a-hardfloat-linux-gnueabi but do check first.
Once you have your kernel tree the defconfigs are listed in arch/arm/configs/ pick one you like.
The method in the same but using a different cross toolchain and a different defconfig. _________________ Regards,

Thank you gents for all your recommendations.
I think I have enough information to have a nice kernel for my hardware. _________________ Powered by Gentoo Linux since 2003 |
