Developping applications for Ledger Blue requires a specific SDK and two compilers

• A standard ARM gcc to build the non-secure (STM32) firmware and link the secure (ST31) applications
• A standard ARM clang above 4.0.0 with ROPI support to build the secure (ST31) applications

• Pick a directory, linking the environment variable BOLOS_ENV to it
• Download a prebuild gcc from https://launchpad.net/gcc-arm-embedded/+milestone/5-2016-q1-update and unpack it into this directory
• Download a prebuild clang from http://releases.llvm.org/download.html#4.0.0 and unpack it into this directory, then link this directory to clang-arm-fropi or rename it

Download the Nano S SDK from https://github.com/ledgerhq/nanos-secure-sdk and link the environment variable BOLOS_SDK to it. You'll have to checkout the tag matching your firmware version.

Download the Blue SDK from https://github.com/ledgerhq/blue-secure-sdk and link the environment variable BOLOS_SDK to it. You'll have to checkout the tag matching your firmware version.

If you get missing include files on an x64 linux device, make sure to install the libc6-i386 and libc6-dev-i386 packages
