Same as with the 2G-IOT, OrangePi also provides a quite inconvenient way (through mega.nz) to get the Android SDKs for the 4G-IOT… Here are the torrents (tar.gz and tar.xz have the same content but xz is much smaller)
Getting the Android SDK
Since I just struggled getting the Android SDK for my little OrangePi 2G-IOT, I felt responsible to share it using bittorrent. The main problems have been, to download all that stuff from mega.nz (it raises limits for users not paying a monthly fee) and another one was, to concat all 7 files to a working tar.gz. I think, the wildcard they use in the OrangePi’s user manual does not expand the filesnames of the parts in the right order. But then, wired errors occur.
If you encounter problems with not being able to create symbolic links when unpacking, just use a real file system as the base for your unpacked archive (e.g. ext4, btrfs, …, but NOT NTFS or FAT).
Here you can find the torrent:
Getting the toolchain
Another dangling point of OrangePi’s SDK is the lack of a toolchain. They have a large download, but it does not contain a toolchain. So just download the correct one from linaro (take the appropriate one for your system, mine is x86_64), unpack it inside the folder where the empty folder toolchain is (here it’s ~/somewhere/OrangePi in the example) located, remove this toolchain folder (rmdir should succeed with a fresh unpack, when it is already a link, use rm) and set a symbolic link to the fresh linaro one.
$ cd ~/somewhere/OrangePi/
$ wget https://releases.linaro.org/components/toolchain/binaries/latest-5/arm-linux-gnueabi/gcc-linaro-5.5.0-2017.10-x86_64_arm-linux-gnueabi.tar.xz
$ rmdir toolchain
$ ln -s
Running the kernel build
Just stick to your User’s guide again and do:
