Hi,
In the SDK 17.1.0 release note (downloaded from https://www.nordicsemi.com/Products/Development-software/nRF5-SDK/Download?lang=en#infotabs), the verification GCC compiler is GCC ARM Embedded 9.2020-q2.major.
But on it is not available on the https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads.
What is the SDK 17.1 verification GCC version used ?
Regards
