Erase EPCS16 using Quartus Programmer tool

[Altera_Forum]

Hello 

I have a small problem with migrating from one FPGA (ep4ce6) to another (ep4ce10) on the same board. Of course, there is already a valid ep4ce6 configuration in EPCS16. I cannot be sure that this configuration is safe for first-starting ep4ce10, so i'd like to wipe configuration before soldering FPGA. But I cannot find a correct way as it should be done using "Programmer" in Quartus Prime Lite 16, neither JTAG or Active Serial mode. I can only overwrite one configuration to another.

Hi, 

 If the entire serial configuration flash needs to be erased, the Quartus II programmer chain should be set up with no file assigned to the configuration flash.To do this the flash device must be manually added to the associated FPGA device: right click on the associated FPGA device and then select Edit -> Attach Flash Device, and then select the appropriate device. Refer below links https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/an/an478.pdf https://www.altera.com/support/support-resources/knowledge-base/solutions/rd11242011_213.html  Let me know if this has helped resolve the issue you are facing or if you need any further assistance.  Best Regards, Anand Raj Shankar (This message was posted on behalf of Intel Corporation)

sorry for that, solution was to scroll options to the right and there was option "erase". I did not see additional options because window was small 

 thank for answer!
