During our work with the OpenRISC platform we were missing our favourite real-time operating system – eCos. Although some porting work had been performed earlier, the eCos port was no longer supported. With the development of the OpenRISC project, as a result of toolchain and other changes, it had stopped working.
Also, it was based on the now obsolete 2.0 version of eCos.
We decided that a freshly updated eCos port could be useful both in our work and for the OpenRISC community, and here it is!
