I tried downloading Arm Architecture Reference Manual Armv8, for Armv8-A architecture profile, which is about 8500 pages. My download succeeds when using my Intel-based laptop, Windows 10, and Firefox. When I try the same file (https://developer.arm.com/documentation/ddi0487/fc/?search=5eec7399e24a5e02d07b2754) with my RPi, The download box at the bottom of the screen says it is a 48MB file which, when clicked on, only shows a black background with a puzzle piece icon with a sad face (which I assume means the file is corrupt).
Any suggestions as to how I can get the download to succeed?
Let me know if there is more info that I should gather.
