Hi Team,
We tried to check the jic file programming setup in Cyclone v gt eval board. For that we have created the system in FPGA design like this:
nios ii reset and exception vector parameter:
firmware code structure we have followed like this:
linker script and other parameters in bsp editor:
make target->mem_init gen used to create hex file.
JIC File conversion parameters setup:
with this jic, we have programmed the fpga, Our expected output from this is 3 led should blink( 1 controlled by FPGA DESIGN and other2 controlled by firmware code).
But with jic programming, firmware controlled led is not blinking.
But in .elf file programming, firmware controlled led is blinking.
do we miss anything? Please guide us to resolve this.

Hi,
With your Exception Vector (RAM IP settings) set to OCRAM, you need your BSP as follows:
Re-build the BSP and project, and re-generate the new .hex using the "mem_init_generate" tools.
Replace your .hex with this new .hex (with above BSP settings) in Platform Designer and create your new .jic and re-try.
Hi Eberlazare,
I have tried with the settings you have mentioned in above response, with that also firmware controlled led is not working.
the setting which i have used:
and i have one doubt that two hex files are generated in mem_init folder, i am using epcq hex file only for generating the jic file programming. Is that correct only right?
Hi,
I think it is because of your Reset Vector offset in your first post, for EPCQ, you need to have offset address for your application as the .jic will also have the .sof at 0x0, so you do not want to overlap it. Anyway, you can find the info here:
https://www.intel.com/content/www/us/en/docs/programmable/683689/current/reset-and-exception-vector-settings.html
You can determine the minimum reset vector offset by using the following equation:
minimum reset vector offset= (.sof image start address + .sof image size) in HEX
You can also try as per the document, set the Reset Vector offset to "0x01E00000".
With that, you need to regenerate the Platform Designer to get the new ".sopcinfo" file and use it to create the new BSP and project.
To confirm you have the Reset Vector offset changed, you can view them when you add in the ".hex" when you try to create the ".jic" file:
Hi,
We have tried as per the steps you have mentioned in previous response. But relative address is not reflecting in the jic file generation.
reset vector offset is changed in nios ii parameter settings ,
hex data parameter is
we have tried with this , but firmware part is not working. Can you please guide us to resolve this as we have less time to give commitment to customer.
