<br>

<b>Step8:</b> After typing the code save the file as <b>main.c</b>.<br>

<b>Step11:</b> Build the project and fix the compiler errors/warnings if any.<br>
[[File:Lpc1768_Keil_11.png]]<br><br>

<b>Step12:</b> Code is compiled with no errors. The <b>.bin</b> file is still not generated.<br>

=Setup Bin File Generation=
<b>Step13:</b> Click on <b>Target Options</b> to select the option for generating .bin file.<br>
[[File:Lpc1768_Keil_13.png]]<br><br>

<b>Step14:</b> Set IROM1 start address as 0x2000. Bootloader will be stored from 0x0000-0x2000 so application starts from 0x2000<br>

<b>Step15:</b> Write the command to generate the <b>.bin</b> file from <b>.axf</b> file<br>
Command: fromelf --bin LedBlink.axf --output LedBlink.bin<br>

<b>Step16:</b> Now enable the linker option to use the IROM1 address from target settings<br>

<b>Step17:</b> .Bin file is generated after a rebuild.<br>
