Is TMS470 still a valid code generation tool version in 2023 or is it absolute?

Hi Stavan,

It is still valid. TI will continue to provide bug fixes for ARMCL (for ARM Cortex-R device). TI will not introduce new features, but there will be regular maintenance releases for bug fixes. 

The latest version is v20.2.0.LTS: https://www.ti.com/tool/ARM-CGT
