With the latest v1.2 release of the MCUXpresso Installer tools, some Windows users see errors when the Installer tries to download the gperf ZIP. Gperf is included in the Zephyr dependencies. This is a known issue, and the Installer will be updated in the next release to resolve this.
In the meantime, there is a workaround to manually download a file, and store it in a cache folder used by the Installer. If the Installer finds the file in that cache, it will not need to download it. These steps assume Windows is used.
It is best to run the Installer at least once, which will create the cache folder, and install the tools. The install log in the Installer will give the URL of the file it tries to download. For this specific gperf error, it fails to download from https://sourceforge.net/projects/gnuwin32/files/gperf/3.0.1/gperf-3.0.1-bin.zip.
Find the cache folder used by the Installer. This folder path will also be shown in the Installer log. In Windows, this path is C:\Users\<username>\AppData\Local\Programs\MCUXpressoInstaller\.cache
Manually download the needed file, and save in the cache folder. Then re-run the Installer, and it will install the tool from the cache folder.
