ARC Project Templates

ARC GNU IDE documentation has been moved to https://embarc.org/toolchain/ide/arc-project-templates.html

There are several ARC projects types available in the C project dialog: ARC Cross ELF32 Target Application, ARC Cross ELF32 Target Static Library, AXS10x Projects, EM Starter Kit Projects.

Note: for each of these project types there is a list of toolchains which are supported by it.

• ARC Cross ELF32 Target Application and ARC Cross ELF32 Target Static Library support all of the toolchains,
• AXS101 Projects supports ARC 600, ARC 700 and ARC EM toolchains,
• AXS102 Projects and AXS 103 Projects support only ARC HS toolchain,
• EM Starter Kit Projects -- only ARC EM toolchain.

Project types are only available in the project creation dialog if at least one of the corresponding toolchain compilers is found in the PATH environment variable or in ../bin/ directory relative to Eclipse executable. Then you choose a project template, list of available toolchains appears on the right side of the dialog. There are only toolchains that are supported by this type of project and also found in the PATH or ../bin/ directory.

If you want to create an application for nSIM, choose ARC Cross ELF32 Target Application. There you can choose either an empty or "Hello World" project template. Please note that this "Hello World" project calls printf() function, so it can not be used on hardware development systems, since they use UART for input/output and libc library does not provide bindings between UART and C standard library I/O functions. For nSIM this project will work fine, but for hardware development systems please choose "Hello World" projects that use UART. On the contrary, "Hello World" projects under EM Starter Kit Projects project type use UART, so they are not suitable for nSIM.

If you want to create a project for a hardware development system, choose one of AXS10x Projects or EM Starter Kit Projects. For each of these project types there is an Empty Project in the list of templates and also Empty Project For templates. If you want to create an empty project for your board, choose an empty project template that is specific for your board and core you are using. These templates contain memory maps of the cores, which are then passed to linker. As for Empty Project templates, they are generated automatically by Eclipse and do not contain any specific information, so you would have to provide a memory map yourself, or your application might not work properly.
