Well, I don&amp;#39;t think that sufficient information for what you were asking for is stored in the ELF header of the image. How about creating another target besides the image, which is a text file listing all source file names that were used to link the program, plus their respective MD5 or CRC32. That way you can compare whether sources have changed.&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;span&gt;Best regards&lt;/span&gt;&lt;br /&gt;&lt;span&gt;Marcus&lt;/span&gt;&lt;/div&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Arm compiler:need help..
