DE1 simple question

can you write one byte from the fpga (DE1 board) to flash (on board) and if so, what is the configuration?

It's basically possible. However, you can only write to an erased memory location, erasure has to be done in sectors. "Write" (programming) operation as well as sector erase requires a multi-cycle sequence, consult the flash datasheet for details. DE1 has also demonstration projects, that are utilizing the flash. Unfortunately they are "illegible" uncommented Verilog code, as commonly known with Terasic Dev Kits.
