 Now we have to update those Devices to a new Firmware based on SDK16 with SD 7.0.1.

&lt;p&gt;now it is working.&lt;/p&gt;
&lt;p&gt;there were some different Problems which has caused my problems:&lt;/p&gt;
&lt;p&gt;* old Bootloader was on 9600 Baud and new was on 115200 Baud. So, after the update of the BL+AD the new BL was running but nrfutil has still used the 9600. Now I use two nrfutil command after each other first with BL+SD on 9600 and second with AP and 115200&lt;/p&gt;
&lt;p&gt;* old Bootloader had a different Flash-Start-Address like the new one. I have to set the new one to the same address as the old was&lt;/p&gt;
&lt;p&gt;* On the old Bootloader the serial pin numbers was defined within the application code. On the new one these defines was within the boards.h file via a pre-processor define.&lt;/p&gt;
&lt;p&gt;* nrfutil version 6.0 was not working. I had to use an older version like version 3.5&lt;/p&gt;
&lt;p&gt;* On old Bootloader HWFC was disabled via sdk_config.h. As we had only RX7TX lines on our Hardware I had also to disable the HWFC on the new Bootloader.&lt;/p&gt;

&lt;p&gt;I see that you get the invalid object value back. Can you please let me know what commands you use to create the DFU images when it is working and when it isn&amp;#39;t working?&lt;/p&gt;
&lt;p&gt;Does your bootloader support BLE and serial, or only serial?&lt;/p&gt;
&lt;p&gt;When you update the SD and app, is the SD the same version as before, or a new one?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
&lt;p&gt;Edvin&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
