Detect JTAG programming with ALT_REMOTE_UPDATE ip

Hi, 

 

my Cyclone IV design uses ALT_REMOTE_UPDATE ip to switch between a factory and application 

bitstream. This works fine. 

 

Now I want to skip any rebooting when the FPGA is currently programmed via JTAG. 

 

The Altera Remote Update IP Core User Guidee states that bit 4 of RU_RECONFIG_TRIGGER_CONDITION 

is set on external configuration (nCONFIG assertion). Does this mean it should be set when programming via  

JTAG also? 

 

Is there any other way to detect if the current image is loaded via JTAG? 

 

Regards, 

Matthias
