migration from EPCQ to EPCQ-A

Hi, on a custom board we have successfully used an altera Cyclone V (5CEBA2) with an EPCQ32 (ASx4). Now we had to migrate from the EPCQ32 to the EPCQ32A. We used Quartus Prime Lite 17.1.0 a...

Hi,

well based on my experience, this behaviour points to the FPGA not identifying the configuration data as valid. Just as an example if you programm some file to the EEPROM containing data for other chip as the one on board (e.g. file for EP4CE15 and EP4CE22 installed). s

My only "workaround" to get the production running again would be to try either setting up a board with active serial interface to the EEPROM (or modifying one board to get Access to the active Serial I/F) and check if programming the EEPROM directly works.

if so, this is no nice workaround to Programm the EEPROM before soldering, but it keeps you in production - if not the issue is definitely related to the configuration file rather the Programming via JTAG...
