Fwd: [Openrisc] Tutorial for running RTEMS on OpenRISC

[Hesham Moustafa]

Hi,

Found out there is a Javascript online simulator (jor1k) that can run
or1ksim binaries (hello, ticker and capture run there perfectly). I am
not sure if this simulator can be embedded to RTEMS Project Webpage
[1]

Hi,

take a look at:
https://github.com/s-macke/jor1k

I have added the RTEMS website and a simple demo.

You are free to link to the github site
https://github.com/s-macke/jor1k
or directly to the RTEMS demo site
http://s-macke.github.io/jor1k/demos/rtems.html

You can send me a new website design if you want.

Sebastian
