IWR1443: Compiler recommendation

HS FAE Germany

Part Number: IWR1443


Hello,
customer starts a new development with the IWR1443 and SDK3.6 and wants to know which compiler we recommend.

We listed contradictory recommendations, according to this page: TI Arm Clang Compiler Tools User’s Guide - 2.1.0.LTS — TI Arm Clang Compiler Tools User's Guide

TI replaces the ARM Compiler by the Clang compiler. But on the same page it is recommended:
>>“Please refer to the SDK for the device family for information on which toolchain to use.”

So in the latest (14 Jun 2022) mmWave SDK 3.6.0 that they are using the quite old ARM compiler LTS 16.9.6 is included. But until now they used the  ARM compiler LTS 18.12.4 because that was included in the CCS V9.3. However, in the latest CCS V12.2 the ARM Compiler LTS 20.2.7 is included.

Regards, Holger
