<h3 class="section">3.3 What to do when you have a binary image</h3>
|
||
|
|
|
||
|
|
<p>A few ROM monitors load binary images, typically <code>a.out</code>, but most all
|
||
|
|
will load an <code>srecord</code>. An srecord is an ASCII representation of a binary
|
||
|
|
image. At it’s simplest, an srecord is an address, followed by a byte
|
||
|
|
count, followed by the bytes, and a 2’s compliment checksum. A whole
|
||
|
|
srecord file has an optional <em>start</em> record, and a required <em>end</em>
|
||
|
|
record. To make an srecord from a binary image, the GNU <code>objcopy</code> program
|
||
|
|
is used. This will read the image and make an srecord from it. To do
|
||
|
|
this, invoke objcopy like this: <code>objcopy -O srec infile outfile</code>. Most
|
||
|
|
PROM burners also read srecords or a similar format. Use <code>objdump -i</code> to
|
||
|
|
get a list of support object files types for your architecture.
