3.3.2. Preparing Software Design for Simulation

Note: Before continuing the simulation, you must successfully build the software ELF file.
To generate software memory initialization file, perform the following command: 
elf2hex <Working directory>/software/app/build/Default/hello.elf \
-b 0x0 -w 32 -e 0x26fff \
<Working directory>/software/app/build/Default/hello.hex

The command converts the software ELF into a HEX memory initialization file for the On-Chip RAM. The RAM have a data width of 32 bits, which starts from base address of 0x0 and ends at 0x26FFF.
