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.
