Configuration program is placed in EPCS4N chips, but there are CYCLONE3 chips and EPCS4N protocol communication?
CYCLONE3 internal chip will have the application?
At that time the experiment process:
1, the circuit boards of original EPCS4N chip off, then on the inside the burning device (a 8 feet), through smartpro software readout chip program,
2, put the empty on chip, 8 feet into the burning device, the program to read in, put the reading into the chip to the circuit board welding, then test is successful,
3, the circuit board advocate chip ALTERA CYCLONE3 (EP3C16E144C8N) to be removed, back to buy another the same chip, welded on the circuit board, the test fails,
4, just began to suspect CYCLONE3 chip problem, to buy the same chip welding on again, still won't do,
Each ace, what reason? How to solve? What good method? High price, please,
The above thank you

This should baa have relationship, should not remember is similar to the PCS4N do a RAM, stored procedures, and have the effect of the boot to boot, replace the EP3 is OK, can work normally, you more change EP3 try to record a program, may be in the process of burning two film guide mechanism,
