Hello,

In addition to what slacker says: "Unable to synchronize with target" means that the flash programmer (on host PC) cannot communicate with the Nios II software in the flash target design. This software is simple firmware that communicates with the PC via JTAG UART peripheral. When the flash programmer starts, it tries to send and receive a reply back from the Nios II firmware; the error message you describe means that this operation timed out.

Anyways, I agree wtih slacker. All pins to the flash programmer target design should be assigned.. without clock and reset Nios II in the flash programmer design will never wake up!
