riscv-angel's Issues

Local instance of angel doesn't seem to work

Riscv-angel works on Firefox when launched straight from the Internet. But, after git-cloning riscv-angel and then using python -m SimpleHTTPServer and entering http://127.0.0.1:8000/run.html in Firefox, I got the familiar emulator webpage, complete with a dialog with "Close and launch" button. I clicked on it, and nothing happens. Why is it apparently broken versus straight-from-Internet launching? I see there is vmlinux in lib/riscv_compiled. I find the HTML and Javascript codes difficult to decipher. Thanks for any help.

Support multiple users

Generate filenames with timestamps instead of a.out

Should also fix #1

Also remove compiled binaries after some amount of time (~1hour?)

How can I use this with my own image, etc?

Is there an easy way to embed this into another webpage and specify what image to use?
Ideally I'd like to be able to use something like <iframe src="https://www.example.com/angel/run.html?image=http%3A%2F%2Fwww.example.com%2Fmy_image.bin in order to embed the emulator into another webpage, but there doesn't appear to be an easy way to do that, or really much of a way at all.

awk arithmetic seems broken

Looks like awk can't do arithmetic:
#/ awk 'BEGIN{print 0,1,2,3}'
270040240 1 1 1

(Maybe it should fault, if floating point is missing??)

Keyboard input doesn't work with Firefox 27.0.1

First off, this is awesome!

However, when it boots in Firefox, normal key strokes appears to be ignored, though return (AKA enter, newline...) works.

It works with Chrome.

Write or Find/Hook-in a better js terminal emulator

Update to latest spec

Currently requires ISA as it was in mid-august.

The links to the demo are dead.

Every link to the demo leads to a 404 page on riscv.org.

fix lr/sc implementation for context switch?

angel doesn't work in Chrome Version 39.0.2171.95 (64-bit)

Hi Sagar

Fix code injection vulnerability if we go back to using compileserver

(see Albert's email)

clrt + L seems to break the shell

...then you scroll up and see the prompt.

Don't force scroll-down if user has scrolled up in term

Actual update for FP handling

improvement over hacky fix from a7d731f

Stop XMLHttpRequest from Caching

Can cause ANGEL to get "stuck" fetching the old binary.

Doesn't work, either on the web or locally

A number of sources say https://riscv.org/angel shoudl work, but it 404s.

The readme at https://github.com/riscv/riscv-angel says https://riscv.org/software-tools/riscv-angel/ and that page exists, but the link for "LAUNCH ANGEL" (http://52.32.189.224/angel-simulator/) doesn't work. The IP "52.32.189.224" belongs to AWS, but seems not to be reachable.

If I check out the project and try to launch locally then downloading the Linux image fails.
