[J-core] Numato board oscilloscope?

[Rob Landley]

What would be involved in running the bus signals for something like the
SD card out to GPIO pins, and what would be involved in having a second
j2 system (on its own Numato/Turtle board) act as a software scope
reading from ITS gpio pins?

There appears to be Linux software out there for this already...
