I use LPC1768 for a project that contains many properties like Usb
BootLoading. 
For this, i&amp;#39;ve tried to use &amp;quot;USB Secondary Bootloader&amp;quot;. It works
really good. (i&amp;#39;ve added CRC) 
But in my project, i have to use software selectable jump task. Not

Hi Marc.&lt;br /&gt;
Yes i have one 24C series. Also i can write, MCU&amp;#39;s ROM section
easily. :) But both of them requires Big Part of image. (4K) Yes it&amp;#39;s
possible to Fill some area with specific value. But this is not
suitable for me. Maybe last chance.&lt;br /&gt;
i think i will change the CRC to bad one. just this can tell that
&amp;quot;something went wrong&amp;quot; to my bootloader software.&lt;br /&gt;
Any idea?&lt;/p&gt;

&lt;p&gt;
Many Thanks&lt;br /&gt;
Bab&amp;uuml;r&lt;/p&gt;

Does your system have any non-volatile memory? EEPROM maybe? You
could also use a Flash register from the on-chip Flash as a dedicated
switch variable.&lt;/p&gt;

&lt;p&gt;
You could use IAP to read write to this Flash register.&lt;/p&gt;
