Contributor[NIOS] New CPU Memory HEX file -> should all NIOS system be regenerated?
You do not have to regenerate the NIOS sub-system if you change the .hex file that you are using to initialize the memory.
You only have to do 2 steps in Quartus:
1) Run 'Update Memory Initialization File' in the Processing menu.
2) Run 'Start Assembler' under 'Start' in the Processing menu.
This will create a new SOF file using the new .HEX file.
Regular ContributorHelo,
Yes, if you have any changes in the hardware system, you must recreate, update or regenerate the BSP project to keep the library header files up-to-date.
The BSP editor will generate the .elf based of your design, which will be used by the .HEX.
ContributorThe question was a bit different ....
I already have a new .HEX file - received it from out SW group.
But, when I replace the "old" .HEX with the "new" .HEX (shown in the GUI screenshot in my previous post), QSYS wants to re-generate the whole NIOS subsystem (RTL generation).
Why? The .HEX, which I received, is based on the same NIOS configuration. The only thing, that has been changed, is the Memory (ROM/RAM) contents, which NIOS works with... I mean no logic has been changed, only memory contents have been changed - so why the whole NIOS subsystem RTL should be re-generated?
Thank you in advance
