We choose cyclone IV EP4CE15F17C8N FPGA for our new NPI production, we use remote update sheme to upgrade FPGA configuration, there are some abormal when factroy image go to application image. I want to know if we could use JTAG when there are factory and application programed in the EPCS chip, and how should I do?
Yes, you could use JTAG for Remote System Upgrade (RSU).
Following link is the RSU design for your reference. This design use Cyclone 10 LP device with Remote Update IP core and ASMI Parallel IP II core. Please refer to following link for more understanding on RSU for Intel FPGA device.
This design is very useful for you in order to understand more about RSU.
"System Console" 's RSU function is only available at 18.0 version or later? I am using 17.1 Prime, and when I generate jic file, there is error " Serial Flash Loader device is missing", so can not generate JIC file?
