identify FPGA reference on board

Hi, We use a FPGA Cyclone 4 EP4CE15F17C8N on our boards and we want to switch to EP4CE10F17C8N (pin to pin compatible) for cost and availability issues. The FPGA is programmed at each power up by...

Hi,


In that case, you can use the method that you has suggested previously. There should be no issue. Or maybe you can view the FPGA top marking to see the device number?


Try to program the FPGA (10 kLE or 15kLE) with the 10kLE bitstream

- At the end of the programmation:

○ If conf_done is OK, the FPGA is a 10kLE and is well configured

○ Else conf_done is KO, the FPGA shall be en 15kLE, the microcontroler starts a new programmation cycle with the 15 kLE binary file.


Regards,
