Configuration program is placed in EPCS4N chips, but there are CYCLONE3 chips and EPCS4N protocol communication?
CYCLONE3 internal chip will have the application?
Consult ace, thank you

The FPGA programming data in EPCS4N chip, this EPCS4N is a can read and write FLASH chip, CYCLONE3 internal not to store data, copy board is very easy, do not need to decode chip, just use assignment EPCS4N chip burn machine,CodePudding user response:
Process:Of the circuit board on the first original EPCS4N chip off, then on the inside the burning device (a 8 feet), through smartpro readout chip application software, put on empty chip, 8 feet into the burning device, the program to read in, again to chip welding buy read good application in circuit board, then test is successful,
Then:
The circuit board advocate chip ALTERA CYCLONE3 (EP3C16E144C8N) to be removed, back to buy another same chips, circuit board welding,
Test failure, just began to suspect that the chip problem, on the same chip welding again to buy, or not,
Each ace, what reason? High price, please,
More thank you

CYCLONE3 is no encryption, in exchange for CYCLONE3 chip is no problem, your test failure may have other reasons, such as luck, luck, and so on, in the film the success rate is a matter of probability and luck, look for a new board (fear of the old version is likely to change film in the process of the bolt hole broken PCB such as local high temperature heat damage), find a good welding craft technicians, the most important thing is to repeat the hand, mouth muttering some auspicious words, I wish you good luck,CodePudding user response:
