2018-09-15: SDRAM - the project compiles fine, I found a CH340-based serial adapter and connected to my FreeBSD workstation, and to the serial port on the DE1 board. Using

$ screen /dev/ttyU0 115200

I get output on the terminal after resetting the DE1 board with KEY0

Simple check passed.
                    First stage sanity check passed.
                                                    Byte (dqm) check passed
                                                                           Aliases found at 0x3800000
                     (Aliases probably simply indicate that RAM
                                                               is smaller than 64 megabytes)
            SDRAM size (assuming no address faults) is 0x8 megabytes
                                                                    Address check passed.
         Linear memory check

looks like terminal output could been improved. Ok, with SW0 set, the output becomes:

Simple check passed.
                    First stage sanity check passed.
                                                    Byte (dqm) check passed

                             LFSR check passed.

The last test takes a while.

2018-09-15: I cloned the repository for the ZPUDemos, and tried out a few projects.
