To see what is all the fuzz about I installed Windows 11 ARM, Insider, on my Raspberry Pi400 (see Tom's Hardware for a guide. warning: it takes several hours).
I used a 120 GB SSD as mass storage.
And am pleased to see it running. A bit slow, Raspberry Pi OS is also not a performer, usable. It is not the definite version, so it may become better.
Lots is missing yet: Raspberry Pi specific drivers for HDMI Audio, Wifi, graphic accelerator
And in general USB COM port drivers and such are not there yet, it is not production ready, manufacturers have some work to do. Will take some time.
Windows 11 looks good, much better IMHO than Raspberry PI OS, and so familiar for a Windows user. It takes its place nicely in my Windows network like any Windows PC.
So how about my Pascal programs?
- Lazarus/FPC for ARM on Windows is not there yet.
- My (compiled on Windows 10 Intel box) Lazarus programs run fine. Copy. install and run! X86 emulation is well done it seems.
- the 32 bit version of Lazarus installs and runs and compiles.
So far so good, a pleasant experience!
