Altera CycloneII EP2C8Q208C8N - BAIXUN dev. kit

Hello,

I've just bought an Altera BAIXUN dev. kit. It is an Altera CycloneII EP2C8Q208C8N.

The board had some default code displays a "BAIXUN welcome" on LCD and digits on 7-seg.

I'll be really glad if some one can assist me to solve my problems:

1. Made a simplest code (AND gate), tried to program it via JTag - Quartus (Web ed.) programmer showed successful result, but actually the default program still ran. Why it didn't work, any idea?

2. As i passed to AS (Active serial) programming using another plug on board.

i succeed to delete the existing program an program mine (to EPSC4).

The logic works as expected (LED lights), but it looks like resetting each time - blinking.

Why does it happen?
