Honored ContributorAS Configuration Problem with EP3C25E144
Hello !
i have designed circuit in EP3C25E144 TQFP FPGA. I am using both configuration scheme i.e JTAG and AS for EPCS64. Using the same connection schemes as mentioned in Altera Cyclon III configuration schemes. MSEL[0..2]= 010 for AS 3.3 Standards Connect MSEL1 with 3.3V. Programmmed is done sucessfully with JTAG but same program is not downloaded in serial device. Quartus II shows no programming error but device seems dead. I probe the memory signals on the Oscilloscope and found one observation that the device cannt go in user mode after the configuration.The data still communicate with FPGA after configuration. Please provide the above remedy for this problem. Regards, Mohsin Hayat15 Replies
Altera_ForumHow are you programming your EPCS64? Does it have it's own programming header? What file are you using to program it?

Is the EPCS64 programmed (you state "same program is not downloaded in Serial device)?
As the programmer forces the change of programming file to the *.pof one when switching between JTAG and Active Serial, this change must be done automatically (you cannot download *.sof to EPCS). Maybe you've set the Option which EPCS to use in QII falsely as IIRC the EP3C25 can be used with the EPCS16 or even the EPCS4, which would be chosen by QII if the device is set to "Auto" in Assignments => Device => Device and Pin Options => Configuration.. - Altera_Forum
Yes Sir,
First i change the .sof to .pof and then download.Using the option from File Menu --> Change Programming File...But problem still - Altera_Forum
Yes i m using seperate Header for JTAG AND AS....

have you checked the EPCS type used on Hardware is same as assigned in QII to ensure the programming file matches the HW? have you chosen the option to generate a compressed programming file - maybe it's worth to start with a non - compressed one
(there was a QII version generating fautly *.pof when compressed option is active, but I think this was round about QII ver.11.x to 12.x but not 13.1 sp1) - Altera_Forum
Yes i have checked the EPCS Device on HW and also set the option in Configuration.I am using QII version 11.0 32bit.I am using the compressed bitstream option.

Try programming the EPCS via JTAG using a .jic file.
Follow the instructions in app note 370 (http://www.altera.co.uk/literature/an/an370.pdf), see page 6 "generating .jic and .jam programming files in the quartus ii software". Once generated, connect to your target via your JTAG connector. Load the .jic file into the QUartus programmer and see if it'll program the EPCS that way. Cheers, Alex - Altera_Forum
oK I WILL TRY AND LET U INFORM.

iAM FACING PROBLEM IN GENERATING .JIC FILE. IN THE INPUT FILE DIALOG BOX, ITS ONLY SHOWS OPTIONS OF *.COF FILE. bUT I AM LOOKING FOR *.SOF FILE. PLEASE HELP

don't click on the 'Open Conversion Setup Data...' button. Follow the instructions I sent you.
1) Set the 'Programming file type:' to 'JTAG Indirect Configuration (.jic)' 2) Select your 'Configuration device:' - EPCS4/16/64 3) Chose an output file '*.jic' (or leave it as output_file.jic) 4) Under Input file to convert, click on Flash Loader and then the 'Add Device...' button. Chose your FPGA (Cyclone III, EP3C25). Click OK. 5) Click on 'SOF Data' and then the 'Add File...' button. Chose your .sof. Click OK. 6) Click 'Generate'. Load the resulting .jic into the programmer and you're off. Cheers, Alex
