Banana pi BPI-R2 source code open on github

How do I actually get this working to produce an image file for myself please. Could you give explicit instructions in the README.md file please ?

I posted a few guidelines here, it might help you:

Basic firmware for debian

If you run: ARCH=arm make mt7623n_evb_bpi_defconfig It will install the default kernel config for you. To build for the ARM platform on X86 you need a cross compiler. I built mine with crosstool-ng, but there are also prebuilt toolchains available, i.e. look for linaro and ARMv7(-a). Then you can build it with: ARCH=arm CROSS_COMPILE=/path/to/cross/compiler/arm-....-linux-gnueabi- make UIMAGE_LOADADDR=0x80008000 uImage dtbs ARCH=arm CROSS_COMPILE=/path/to/cross/compiler/arm-....-linux-gnu…

When I run ./build.sh, I got errors:

Makefile:961: recipe for target ‘drivers’ failed make[1]: *** [drivers] Error 2 make[1]: Leaving directory ‘/home/liu/project/bpi-r2/BPI-R2-bsp/linux-mt’ Makefile:50: recipe for target ‘kernel’ failed make: *** [kernel] Error 2

Would anybody give some suggestion? Thanks!

please post your full log…maybe you have not installed some requirements (gcc-arm-linux-gnueabihf, u-boot-tools)

[biga]

select mode 1. log file: build.log (4.2 KB)

[frank-w]

have you install requirements?

fatal error: linux/compiler-gcc7.h: No such file or directory

looks like gcc-arm-linux-gnueabihf (or something from gcc-core) is missing

[biga]

I installed the tools:

arm-linux-gnueabihf-gcc --version

arm-linux-gnueabihf-gcc (Ubuntu/Linaro 7.2.0-6ubuntu1) 7.2.0

which host-system do you use to build? recommended is ubuntu 16.4, i had build successful on ubuntu 14.4

maybe you have to use gcc6

[biga]

My host is Ubuntu 17.10.

[BitMaster]

FYI i had to do some manual fixes to get it compiling with gcc7, I don’t have access to a patch right now, but they are quite easy to do. However you could also use gcc6 of course, that should work out of the box.

Guys, do you have any plans to provide R2 source code for Raspbian as well? I tried the Rapsbian image from https://dev.banana-pi.org.cn/Image/BPI-R2/2017-09-14-raspbian-stretch-preview-bpi-r2-sd-emmc.img.zip and liked it much. It uses less RAM and CPU power and behaves more responsive then Ubuntu image. Raspbian seems to be a better choice for ARM based board then Ubuntu to me. Don’t you think so?

We just validate the building proccess on Ubuntu 16.04 64bit, can you please try this OS on host. And the version of arm-linux-gnueabihf-gcc is newer than I’m using, gcc version 5.4 is recommended.

[biga]

Thank you all! I finally build successfully on Ubuntu 16.04.
