How to

Good evening, how do you create a .img file.

Embedded application.
I have latest DDE

I have tried to find information on the tinternet but to no avail.

Many thanks in advance

Basically the same way you write an img file to a SD card. The same Windows (or Linux/OS X/RISC OS) tool will be able to dump the content of a SD card to an img file.

She mentions creating an img file, and the DDE… So she might be asking how to actually build RISC OS.

If that’s the case:

There’s an old guide to building the Pi version on my blog – https://heyrick.eu/blog/index.php?diary=20131105

There’s also this – https://www.riscosopen.org/wiki/documentation/show/Beginner’s%20guide%20to%20ROM%20builds

But remember, you’re building an operating system. It should “just work” but if for any reason it doesn’t, all that rubbish that went scrolling by ought to give an indication of what happened. It’ll be technical in nature because it’s the output of the build tools (compiler and assembler).
