This version supports a vast range of ARM devices from manufacturers such as STMicroelectronics, NXP, Renesas, and Texas Instruments IAR Systems Context for Version 8.32.x EWARM | Arm IDE in the IAR Embedded Development Platform
The primary reason engineers seek out 8.32.1 over the base 8.32.0 is a specific bug fix in the C-SPY debugger.
In 8.32.0, there was a frustrating issue with Live Watch windows when using J-Link probes with SWO (Serial Wire Output). Variables would randomly show <not available> despite being in scope. 8.32.1 resolved this without requiring any code changes.
If you are using a Segger J-Link Ultra+ or EDU probe on a Cortex-M4, this patch is mandatory.
Version 8.32.1 uses the IAR C/C++ Compiler for ARM v8.32.1. Unlike the dramatic changes introduced in version 9.x (new XML linker and extended C++17 support), 8.32.1 is the culmination of the 8.x architecture.
std::make_unique, generic lambdas, or variable templates, this version handles them reliably without the bugs seen in earlier 7.x releases.
