Release Information

This is the 5.1.1.LTS Long-Term Support (LTS) release. The tiarmclang compiler tools provide software development tools including the compiler, assembler, and linker, among others, which can be used to develop applications with C/C++ source code for loading and running on Arm Cortex-M and Cortex-R series core processors.


For definitions and explanations of STS, LTS, and the versioning number scheme, please see https://software-dl.ti.com/ccs/esd/documents/sdto_cgt_compiler_version_numbers_and_what_they_mean.html.


PLEASE NOTE: The X86 MacOS installation of the tiarmclang 5.1.1.LTS relies on a libc++.1.dylib that is available in more recent versions of the MacOS. It is known to work with MacOS version 13.6, but it does not work with MacOS version 10.13.6.

What's new

  • Availability of tiarmclang 5.1.1.LTS package for Arm MacOS
  • Support for Cortex-M33 with DSP Disabled Configuration
  • Improved Performance of Emulated Double Divide and Multiply Runtime Support
  • Position Independent Code / Dynamic Linking Support
  • Full Support for Cortex-M55, Cortex-M85, and Cortex-R52+
  • Performance Improvements Across Multiple Supported Processor Variants
  • Bug fixes
