FPGA active serial programming

Hareesh M. (hareeshp) OP (Company: Mindteck) 2017-08-31 14:04 #5128465

hi,

I'm currently using the cyclone ii (ep2c20f484c7) fpga, and i want to do 
the active serial programming.
i configure the device for active serial programming as the following 
way

mode: Active Serial Programming
Device: EPCS16 (But it should be EPCS4 nah?)
when i change the device from EPCS16 to EPCS4 and adding the .pof file 
it is not uploading to the eeprom.

Is the FPGA configured correctly for AS mode? Check how the MSEL pins 
are configured.

Actually i couldn't find the configuration switch on my fpga. :(

Do you have a link to the schematic of your board?
The configuration options are usally some pins on the fpga device.

So simply look for the MSEL Pins in the schematics...

Both MSEL pins are hardwired to GND that means: AS mode.

The MSEL pins are both connected with GND.
Look at the chip documents to see what that means.

which means i can do the active serial programming without configuring 
the msel pin, because it is already connected to ground.
