I am able to use the UART and at the same time load and run images over the JTAG interface using OpenOCD. Next, I plan on trying GDB. I will try to document the setup soon, but it just requires ~10 jumper wires to connect the MiniMod to the Pi GPIO header. I need to use it, because I discovered that the RKI image no longer runs on the Pi. The samples such as ticker still work, so I'm sure it is a problem with the RKI code itself. > > Meanwhile I have set up a development blog and a google calendar for the > project: > > http://asuolgsoc2014.wordpress.com/ > > > https://www.google.com/calendar/embed?src=mo5guprvls0ip24rnrjio4ogks%40group.calendar.google.com&ctz=Europe/Lisbon > > I will try to come up with more news during the weekend. > > Looks good.
