Thank you so much and all the more for this great initiative of providing me with an MVME6100 to get the first hand feeling for target development. I have started working on the next step to get EPICS7 running with RTEMS5 on qemu. As of now, it's looking a bit challenging because I am a bit new to this and resources on the internet are also hard to find.
Still, I will try my best and report the updates here in the afternoon (European Time). I can understand the situation, everyone is stressed due to this Corona Virus. Hoping for things to improve everywhere.
