Step12: Code is compiled with no errors. The .bin file is still not generated.
Setup Bin File Generation
Step13: Click on Target Options to select the option for generating .bin file.
Step14: Set IROM1 start address as 0x2000. Bootloader will be stored from 0x0000-0x2000 so application should start from 0x2000
Step15: Write the command to generate the .bin file from .axf file
Command: fromelf --bin LedBlink.axf --output LedBlink.bin
Step16: Now enable the linker option to use the IROM1 address from target settings
Step17: .Bin file is generated after a rebuild.
Step18: Check the project folder for the generated .Bin<ER_ROM1> file.
