https://devzone.nordicsemi.com/f/nordic-q-a/93790/dfu-compatible-with-uart-and-bleHello, I try to transplant some code of project \examples\dfu\secure_bootloader\pca10056_uart to project \examples\dfu\secure_bootloader\pca10056_s140_ble. Trying to make uart dfu compatible with ble dfu, but an error occurred when compiling the linken-USTelligent Community 13Fri, 11 Nov 2022 15:01:06 GMThttps://devzone.nordicsemi.com/thread/395362?ContentTypeID=1Fri, 11 Nov 2022 15:01:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f8c8bbb3-569f-432e-a67b-8ffff6d8ae08Amanda Hsieh<p>Hi,&nbsp;</p> <p><span>B</span><span>ecause the size of the bootloader code has increased with your changes, you need to adjust IROM settings for the project.&nbsp;If you&nbsp;need more space for the bootloader you can allocate more by reducing the start address (IROM&nbsp;start, and increase the size setting with the same amount). You can see an example on how this is done in the debug variant of the bootloader project.</span></p> <p><span>Regards,<br />Amanda H.</span></p><div style="clear:both;"></div>
