Hello,

I am trying to work on designing a bootloader. For this I
was trying to understand the hex file for LPC. I understood quite a lot
through the link http://www.keil.com/support/docs/1584.htm. But I could not
understand this first line from the hex file itself.

:0400000500000000F7

:020000040000FA

:1000000018F09FE518F09FE518F09FE518F09FE5C0

:1000100018F09FE50000A0E1F0FF1FE518F09FE554

:100020005400000040000000107600004400000072

:1000300048000000000000004C00000050000000DC

I could not find the meaning of code 05. What does it signify? And when I
read the hex file from the controller itself, this line was missing while
other all the lines were same.

Whatever help you all can provide me will be great.

Thanks in advance

I think that record type 05 indicates the start address of code.

Have a look at the following document. It describes the Intel Hex-
Format. Record type 5 means "Start Linear Address Record".
