Program the EPCS via the JTAG interface (cycIII)

[Altera_Forum]

Hi Guys, 

 I am trying to re-program the EPCS through the FPGA JTAG port. Does anyone familiar if Altera has some C code or AppNote explaining how to do so in the attached topology?   The basic idea is to mimic the Byteblaster and quartos programmer while using an embedded uP.   I Think that "Altera Srunner/Jrunner" Softwares does not serve my purpose (if someone disagree, pls say how?)   so i have tried to use the Jam STAPL software along with the SFL megafunction, but i am not sure it the correct way (so far i have got unrecognized device error...).   Can someone suggest a way of doing so?   Thanks

I think using a embedded STAPL player is the best way do it. 

 You'll need to convert the JTAG Indirect Configuration (.JIC) file Quartus uses into a .JAM file, of course.

Hi rbugalho, 

I did this of course, I had converted the .JIC file into JAM file using the Altera programmer, as mention in AN370.  we are using linux OS, So the software guy had converted and implemented the Windows functions (of the STAPL) to linux functions, and mapped the IO's and the std file managament, but still no luck, he had succeded in reading the SFL version(#31), but still we get an error of : Unrecognized device Exit code = 6 … Unrecognized device   he added some debuging print out to the code, and we are getting now:   jam_process_exit() error code# 6 jam_process_action() error code# 6 thus the error came from this rotines. Does anyone success performing this process? Are you familer with any AN for the STAPL beside the Readme file of the STAPL?   Thanks,

Hi, 

what JAM player are you using?  BTW, if you have an Altera programing cable (USB-Blaster, etc), Quartus comes with it's own JAM player, both under Windows and Linux: quartus_jli So, you can use that to test your JAM files.  BTW, you may want to take a look at AN 122 and 586.

Hi, 

I am using VERSION 2.5, is there other version? I will look into the quartos_jli as you mentioned,  Thanks

Hi, 

I have found the quartus_jl application in C:\altera\90\qprogrammer\bin I have executed it with : quartus_jli.exe C:\JAM\top_design.jam -a PROGRAM   This is what I have got :   ******************************************************************* Info: Running Quartus II Jam Tools  Info: Version 9.0 Build 132 02/25/2009 SJ Full Version  Info: Copyright (C) 1991-2009 Altera Corporation.

Procedure: 

1) Create .JIC file.   2) In Quartus Programmer, setup necessary infomation. Choose .jic file.   3) Erase EPCS content (for verification purpose)  4) In Quartus Programmer, Check Program function, then create .jbc or .jam file. (File-> Convert programming files)  5) Open NIOS-II command shell.   6) Using quartus_jli.exe to program device with .jbc file.  $ quartus_jli.exe -c 1 -aCONFIGURE DE0_Nano.jbc  $ quartus_jli.exe -c 1 -aPROGRAM DE0_Nano.jbc
