This repository contains the source code and build scripts for generating the loader tool used to create LDR files. LDR files are the executable format for the ADSP-SCxxx on-chip Boot ROM. We need to handle this format for initial booting of the processor (so boot loaders or bare metal applications).
To put it simply, LDRs are just a container format for DXEs (which are just a fancy name for programs in the Blackfin binary object code format). A single LDR is made up of an arbitrary number of DXEs and a single DXE is made up of an arbitrary number of blocks (each block contains starting address and some flags).

To build the Linux-hosted bare metal toolchain: make install_arm_none_eabi_toolchain_release
-
To build the Windows-hosted bare metal toolchain: make install_arm_none_eabi_toolchain_release BUILD_WINDOWS_CROSS=yes
-
To build the Linux-hosted Linux-targeting toolchain: You will need to ensure that the kernel sources that you use can be downloaded into the gnu-arm/src directory in order for the toolchain to build
make install_arm_linux_gnueabi_toolchain_release
