New ContributorReset offset for Cyclone 10 GX 085
Hello!
I have in my system a Cyclone 10 GX 085 FPGA (10CX085YF672I6G) and connected throught the Active Serial interface (4x) to a Winbound W25Q256JW device (256 Mbit).
If I use the reset vector (set in Platform designer in the NiosV parameter window) as 0x02000000, then when I run niosv-bsp command it gives me the follwowing error:
2026.02.04.14:45:36 Error: .entry section mapping not created because reset memory region not located at base address: 0x2000000

2026.02.04.14:45:36 Error: CPU "My_NiosV" reset memory "intel_generic_serial_flash_interface_top_0_avl_mem" has no matching memory region.
But if I us use the reset vector at 0x01000000 I don't get the error anymore.
The problem is that when I load the hex file I eventually produce into the "Convert programming file" window, I get the following error:
The requested address range for page app.hex (0x02000000 - 0x0201DFCF) overlaps with the address range for page Reserved Option Bits on flash device 2 (0x02000000 - 0x0200001F)
If I change the reeet vector to 0x01000000 then I don't get the error.
So in summary
reset vector 0x02000000 : error when I generate the BSP
reset vector 0x01000000: error when I generate the JIC file
Any idea what might be happening? I included the project folder.

Hi tato,
You’re seeing two separate issues:
- BSP @ 0x02000000 fails because Nios V requires the reset vector to be exactly the base of the chosen reset memory region (your GSFI avl_mem base not equal to 0x02000000). Refer :5.10. Summary of Nios V Processor Vector Configuration and BSP Settings
- JIC packaging @ 0x02000000 fails because the first 32 bytes there are reserved (Option Bits), so app.hex starting at 0x02000000 may overlaps.
Could you try:
- If GSFI base is 0x01000000, start HEX at 0x01000000. Refer :5.10. Summary of Nios V Processor Vector Configuration and BSP Settings
- If you must use 0x02000000, start HEX at 0x02000020 to avoid the Option Bits area. Verify with the generated .map and avoid HEX overlap errors. Refer: 2.3.1.4.3. Defining Address Span Extender Linker Memory Device
Also, make sure GSFI parameters match your flash and configuration mode. Refer: Nios® V Boot Option
