https://devzone.nordicsemi.com/f/nordic-q-a/17101/protect-the-firmware-on-the-beaconHello I want to understand how far the firmware that is burnt on to a Hardware is protected. Is it possible to actually read the firmware from a device (if the device has GVDC Pins) and re engineer the HEX file from it? What are the typical safeguardsen-USTelligent Community 13Mon, 17 Oct 2016 20:28:54 GMThttps://devzone.nordicsemi.com/thread/65595?ContentTypeID=1Mon, 17 Oct 2016 20:28:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3761d640-8000-43b7-92c9-23d704eac836pltv<p>Thanks. But comment from @Wojtek says that it is still possible to dump firmare protect by that register and reverse engineer. Whats the final word on this?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65594?ContentTypeID=1Mon, 17 Oct 2016 12:26:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:eddc02eb-f1cf-46b7-837b-c23e5ab0c238Sigurd<p>After you have successfully programmed your device, you can enable readback protection with the RBPCONF register. You will then have no access to the flash or RAM from the outside. When unlocking the device, the RAM and FLASH will be erased.</p> <p>See chapter 8 in <a href="http://infocenter.nordicsemi.com/pdf/nRF51_RM_v3.0.pdf">the reference manual</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65593?ContentTypeID=1Mon, 17 Oct 2016 11:54:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f5da8104-f665-4aa2-96d1-8d1e8233546fWojtek<p>There is RBPCONF register, you can read about it in reference manual. HOWEVER it does not give you 100% security, as there already is method of dumping firmware protected by that register. But i think this is the only firmware security feature that is implemented in nrf51</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65591?ContentTypeID=1Mon, 17 Oct 2016 11:48:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0947fa63-38bf-4b60-b79b-0fea8b71acddpltv<p>nRF51822 QFAC</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65592?ContentTypeID=1Mon, 17 Oct 2016 11:47:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:12b55998-2da5-4e15-9951-c2d59d6862cdWojtek<p>Which chip are you asking about?</p><div style="clear:both;"></div>
