Hi I am in the process of converting a MAX10 Nios2 design to a MAX10 NiosV. It boots from Flash loaded into DDR
All is good with the compiling apart from I need to convert the elf file to a hex file.
Nios2 was done with Eclipse tools and it created the script
alt-file-convert.exe -I elf32-littlenios2 -O hex --input=app.elf --output=mem_init/ext_flash.hex --base=0x44000000 --end=0x45ffffff --reset=0x44430000 --out-data-width=8 --boot="C:\intelfpga_lite\23.1std\nios2eds\components\altera_nios2\boot_loader_cfi.srec"
Now i have to use NiosV command line to do the same, but the alt-file-convert.exe command doesnt exist.
I think it may be something like this:
elf2flash --input=sw/app/build/app.elf --output=sw/app/build/mem_init/ext_flash.hex --epcs –-offset 0x0 --end=0x45ffffff --boot="C:/intelFPGA_lite/23.1std/niosv/components/bootloader/niosv_g_bootloader"
Note the --base and --reset that alt-file-convert.exe used can't be used with elf2flash - is that
correct?

I dont think I should have "--epcs" mode set for QSPI?
if I remove that then I can add "--base" and "--reset".
That only leaves "--out-data-width=8" - I take it I dont need that for QSPI either
Also "-I elf32-littlenios2" and "-O hex" are superfluous for elf2flash I take it.

Hi
Could you try the command below:
nios2-elf-objcopy -O ihex file.elf output_file.hex

nios2-elf-objcopy is not recognised by niosv command shell.
Moreover I got elf2flash to create a hexfile but when I use 'convert programming file' in Quartus to create a pof file for qspi programming , I discover that the hexfile isnt Intel format which it meeds to be for it to work!
So I reiterate:
What is the NiosV equivalent of the Nios2 command?:
alt-file-convert.exe -I elf32-littlenios2 -O hex --input=app.elf --output=mem_init/ext_flash.hex --base=0x44000000 --end=0x45ffffff --reset=0x44430000 --out-data-width=8 --boot="C:\intelfpga_lite\23.1std\nios2eds\components\altera_nios2\boot_loader_cfi.srec"

It seems elf2flash creates an s-record file which is no good .
I need an equivalent for alt-file-convert.exe which created an Intel hex file!!!
I think I can use a 3rd party hex editor to convert between s-records and Intel Hex though, I can try that.
elf2hex creates an Intel hex file but doesnt allow a bootloader to be added, although the command line doesnt complain when I add it!
I tried it and it created a file 78MB which is an order of magnitude bigger than it should be.
It seems to me Nios V toolset isnt ready for me to replace Nios II .
Moreover Platform designer in the Pro version of Quartus has a BSP editor. Thats all very well but Quartus Pro doesnt support MAX10!!

Hi
The nios2-elf-obj is available under the nios2 command shell.
To launch you can use the nios2-elf-objcopy.exe shown below:

Hi
Any update on this case?
Have you managed to locate the exe in your windows system?

Thats the point I am trying to use Nios V not Nios II !!!!!
Please try reading the thread.

Hi
Sorry for the confusion.
For the NiosV there is a new tool to be used for creating the hex for bootloader.
The command tool to used is :
elf2flash --input software/app/debug/<Nios V application>.elf \
--output flash.srec --reset <reset offset + base address of GSFI AVL MEM> \
--base <base address of GSFI AVL MEM> \
--end <end address of GSFI AVL MEM>
riscv-none-embed-objcopy --input-target srec --output-target ihex \
flash.srec <Nios V application>.hex
Instead of one command to generate the hex it is separated into 2 steps.

Thats great - just what I wanted..
One more thing:
My Nios2 haad use of Exception Vector set within Platform designer.
For Nios V it must be set with the Nios V command shell because MAX10 doesnt have a BSP editor!
Any advice how I do that with the niosv-bsp command?

Sorry I was bit hasty there..
riscv-none-embed-objcopy doesnt exist in Quartus 23.1 std/lite edition.. The documentation is incorrect.

Hi
For the NiosV they make the exception vector editable in the BSP Editor.
You are able to change the exception vector in the BSP Editor under the BSP linker script.
Which doc you referring to that uses the riscv-none-embed-objcopy ?

riscv-none-embed-objcopy is in your reply dated 20th June.
Once again, I repeat, BSP editor is only available in Quartus Pro and Quartus Pro doesnt support MAX10!!
Nios V isnt properly supported it seems - if you want me to migrate from Nios2 to NiosV then Intel need to sort the tools out.

Here is the answer to one issue..
https://www.intel.com/content/www/us/en/support/programmable/articles/000092029.html?wapkw=riscv32-unknown-elf-objcopy
Still an answer to this..
One more thing:
My Nios2 had use of Exception Vector which was enabled in the NiosII IP within Platform designer.
For Nios V it must be set with the Nios V command shell because only Quartus Pro has BSP editor in Platform Designer and Quartus Pro doesnt support MAX10.!
Any advice how I do that with the niosv-bsp command?

Hi
For the Max10 that is using the FPGA Std/lite.
You could launch the BSP-editor manually using the command line.
Launch the niosv-command shell and enter the command "niosv-bsp-editor"
If you could not find the niosv-command shell, it is located here.

Thats useful - however with all the above I still cant run NiosV Hello.
On the other hand NiosII Hello works just fine on the same Platform Design and hardware.
I am using MAX10M40 .
I am booting from Internal Flash(UFM) into External Ram. The Hello example is too big perversely to be loaded into internal RAM.
I create the BSP:
niosv-bsp -c --sopcinfo=hw/q_sys.sopcinfo --type=hal sw/bsp_hal/settings.bsp
I use niosv-bsp-editor as you suggested to check/edit settings and regenerate.
I add app:
niosv-app --bsp-dir=sw/bsp_hal --app-dir=sw/app_hal --srcs=sw/app_hal/hello.c
cmake:
cmake -S ./sw/app_hal -G "Unix Makefiles" -B sw/app_hal/build
make:
make -C sw/app_hal/build
create srec file and append bootloader file:
elf2flash --input=sw/app_hal/build/app_hal.elf --output=sw/app_hal/build/mem_init/onchip_mem.srec --reset=0x4a000020 --base=0x4a000000 --width=8 --end=0x4a06ffff --boot="C:/intelFPGA_lite/23.1std/niosv/components/bootloader/niosv_g_bootloader.srec"
convert to hex:
riscv32-unknown-elf-objcopy --input-target srec --output-target ihex sw/app_hal/build/mem_init/onchip_mem.srec
sw/app_hal/build/mem_init/altera_onchip_flash.hex
I add the hex file to UFM and add the .sof file in "Convert Programming files" to create a pof file.
I program my device but nothing appears on juart-terminal.
Furthermore you cant enable debug on the NiosV because it requires Single Uncompressed Image with Memory initialisation
so it seems.
If I do that it reduces the amount of UFM available such that its insufficient to hold the Hello program!
I know its stupid isn't it.
In practice I would be using QSPI for softawre storage which worked great for NiosII but because that didnt work with NiosV I wanted to try something very simple.
Has anyone got NiosV to work properly?

Hi
Have not tried out on the MAX10 before, however I did managed to run the hello world on other boards
Could you try just booting the hello world elf from the memory itself instead of using the bootloader method?
I followed the steps from the link below on getting the hello world running in other boards.

Jingyang, Teh

I tried that - it seems to load ok (- my DDR is at 2000000) do you see anything wrong? Nothing still on the terminal.

Hi
Is it possible that you share me your bsp settings and a screenshot of your Platform Designer "Address Map" tab?
From the looks of it the elf is set to launch at address 0x20 000 000 where as your ddr is set to 0x2 000 000.
Could you double check your linker settings in the bsp settings?

Sorry - DDR is at 20000000 - my typo.
bsp settings attached
It can only be one of 2 things..
i)NiosV isnt running
ii)NiosV is running but the jtag UART isnt.

This is a problem as well!
It never rains when it pours!
I need ALTPLL and it fails in Quartus23 - going to try the suggested fix.
