How to build the LINUX tools?

Why build the toolchain from source? It comes with prebuilt binaries from launchpad. Building GCC from scratch is not something I would recommend for any embedded developer, as it's a very complex operation. Grab the gcc-arm-none-eabi-*-linux.tar.bz2, unpack it to your desired directory and modify /components/toolchain/gcc/Makefile.posix to this path. If you get any weird errors running arm-none-eabi-gcc, it's probably because you're on 64-bit linux, and need to install "ia32-libs" for x86 compatibility.

I agree with your last point here. We can always provide methods or tools to ease the development. For instance: provide scripts to pull and build the external library. I'll bring this up internally.

Cheers, Håkon

Hi,

It looks like you copied a dot (.) from the PDF file that was not supposed to be part of the link. Please follow the link to the correct page: https://launchpad.net/gcc-arm-embedded-misc/native-build-tools/20150408

The reason why micro-ecc is not included in the SDK, is that the license of the library does not allow us to distribute it. The user is therefore required to download and install the library manually. We are working on a better solution for this in the future.

Best regards,

Jørgen

No, You don't have to. A newer version would be better. As long as It supports your gcc-arm. My distribution is Fedora 25. What kind of example would you like? The hex file of dfu? I used the example of SDK 12.2. First, put the arm-gcc in a right place and compile the bootloader_secure example, then you may encounter the issue. I'm glad to share any detail here.

If possoble, can you send me some example? my mail is lglgang@126.com I only use the bootloader DFU to download the new code to the board through bluetooth.

I'm using gcc to develop nrf52. I think you could put the gcc tools in /usr/local/. Refer to "yoursdk/components/toolchain/gcc/Makefile.posix". In my case, it is /usr/local/gcc-arm-none-eabi-4_9-2015q1. Then go to the folder where the makefile exists to compile.
