Nios2-flash-programmer can't find EPCQ512 of Statix V

[Altera_Forum]

Hi, 

I have a Statix V & EPCQ512 in my design, the Nios(Gen2) image locating in the EPCQ @ offset 0x3000000  I've connected Altera Serial Flash Controller to the Nios. the clock sink of the Flash controller is 20MHz (less than 25MHz as requested), and the Nios Processor is running on 110MHz. as shown below:  http://www.alteraforum.com/forum/attachment.php?attachmentid=11945&stc=1   My Nios software locate in EPCQ offset 0x300000 and the vectors set to : http://www.alteraforum.com/forum/attachment.php?attachmentid=11946&stc=1   I've create JIC file with the follow settings: http://www.alteraforum.com/forum/attachment.php?attachmentid=11947&stc=1   When I'm Burning the EPCQ by using JIC, everything is Normal  the default bootloader of the Nios, copy the image from the EPCQ to the DDR and run the application, so far so good.   Now, I'm trying to burn only the Nios image in the EPCQ, for FW upgrade. I'm using nios2-flash-programmer command line or Nios II Flash Programmer Tool.  I'm converting the elf to flash file by using: elf2flash --input="D:/app.elf" --output="D:/app.flash" --boot="nios2eds/components/altera_nios2/boot_loader_cfi.srec" --base=0x10000000 --end=0x14000000 --reset=0x13000000 --verbose   and programming the the flash by using: nios2-flash-programmer "D:/app.flash" --base=0x10000000 --accept-bad-sysid --device=1 --instance=0 '--cable=USB-Blaster on torenpc [USB-1]' --program --verbose    I'm getting the follow error: No CFI table found at address 0x10000000  Do I missing something? I also follow the application note AN-736 (Nios II Processpr Bootoing From Serial Flash (EPCQ)

You need the --epcs to specify it is a EPCS/EPCQ rather than CFI flash. 

 For example:  $nios2-flash-programmer "REMOTE_epcq_controller_0_avl_mem.flash" --base=0x0 --sidp=0x2081060 --id=0x55 --timestamp=1469019010 --device=1 --instance=0 '--cable=USB-Blaster on localhost [USB-0]' --program --verbose --erase-all    You also could use this for testing  $ nios2-flash-programmer --epcs --base=0 --debug  I hope you do not get "No EPCS registers found" kind of errors. see below.  Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Resetting and pausing target processor: OK Processor data bus width is 32 bits Looking for EPCS registers at address 0x00000000 (with 32bit alignment)  Initial values: FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF  Not here: reserved fields are non-zero Looking for EPCS registers at address 0x00000100 (with 32bit alignment)  Initial values: FFFF8F98 FFFFAF1B FFFFAF90 FFFFCFF2 FFFFEF19 FFFF2F18  Not here: reserved fields are non-zero Looking for EPCS registers at address 0x00000200 (with 32bit alignment)  Initial values: FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF  Not here: reserved fields are non-zero Looking for EPCS registers at address 0x00000300 (with 32bit alignment)  Initial values: FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF  Not here: reserved fields are non-zero Looking for EPCS registers at address 0x00000400 (with 32bit alignment)  Initial values: FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF  Not here: reserved fields are non-zero No EPCS registers found: tried looking at addresses  0x00000000, 0x00000100, 0x00000200, 0x00000300 and 0x00000400 Leaving target processor paused
