https://devzone.nordicsemi.com/f/nordic-q-a/90280/uart-upgrade-firmwareHello, I use SDK16 and softdevice S140. I want to use UART to upgrade firmware. Do you have sample code for SDK16? Do I need to install python and nrfutil on my computer? If yes, are there linux versions for python and nrfutil? Or need other tools?en-USTelligent Community 13Fri, 22 Jul 2022 12:46:00 GMThttps://devzone.nordicsemi.com/thread/378310?ContentTypeID=1Fri, 22 Jul 2022 12:46:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d94eeaf5-d382-49a3-847f-810a64c248b6Hung Bui<p>Hi Ted,&nbsp;</p> <p>Yes it&#39;s supported in SDK 16.&nbsp;<br />You can find the example in&nbsp;\examples\dfu\secure_bootloader\pca10056_uart<br />See the documentation here:&nbsp;<a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/sdk_app_serial_dfu_bootloader.html?cp=8_5_1_4_4_4">infocenter.nordicsemi.com/.../sdk_app_serial_dfu_bootloader.html</a></p> <p>You will need to install python and nrfutil on your computer.&nbsp;<br />I&#39;m not very familiar with Linux but as far as I know nrfutil should work fine on Linux.&nbsp;</p><div style="clear:both;"></div>
