Hi,everyone!
I want to initial elf file fixed on chip ram,so that the processor can boot directly from internal memory without downloading.
I generated the ram initialization file according to the software manual.
perform the following steps:
1. Right-click the application project.
2. Point to Make targets and click Build to open the Make Targets dialog box.
3. Select mem_init_install.
4. Click Build. The makefile generates a separate file (or files) for each memory
device. The makefile inserts the memory initialization files directly in the Intel
Quartus Prime project directory for you.
5. Recompile your Intel Quartus Prime project.
Quartus report warings:
When I opened the hex file generated, I found that it was not in the right format:
When eclipse generate hex file,console print as follow:
make mem_init_generate

Did I do it correctly?
if not ,please tell me how to do?
