Hello Huaping,
you can simply concatenate two files in the following way as

% cat BOOT.hex APP.hex > ALL.hex

and delete S8 or S9 record.

% grep -v 'S[89]' ALL.hex > ALL2.hex

Then you can get it.

% arm-none-eabi-objdump -D -M force-thumb -m armv5te ALL2.hex
ALL2.hex:     file format srec

Isn't it OK?

Hello,

there are multiple ways to do this. I'm using the open source 'SRecord' tool for these kind of things (see  CRC Checksum Generation with ‘SRecord’ Tools for GNU and Eclipse​ how this tool can be used for other tasks too).

I hope this helps,

Erich

I was going to recommend Srecord but you beat me to it:smileyhappy:

[huaping]

Hi Erich:

    Is it to use srec_cat tooling? I refer to the manual, but still can't find how to merger two files to one, no example.

    Can you help me?

   Thanks a lot!

Fred

Hello Huaping,

it is as simple as this:

srec_cat app.s19 boot.s19 -o combined.s19
