https://devzone.nordicsemi.com/f/nordic-q-a/54207/no-elf-version-debug-avialableHi, I am the first time programming with nordic and Segger. As I received the Thingy91 I just the getting started assistent to set up the toolchain. This worked fine so far, but now I opened the asset tracker example and wanted to build the zephyren-USTelligent Community 13Mon, 11 Nov 2019 12:10:25 GMThttps://devzone.nordicsemi.com/thread/219454?ContentTypeID=1Mon, 11 Nov 2019 12:10:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:612457f3-2a34-4431-b17f-f09a86d907ccDidrik Rokhaug<p>Hi.</p> <p>The documentation you linked to is for NCS version 0.3.0, which is outdated. Here is a link to the most recent documentation: <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_programming.html#gs-programming">https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_programming.html#gs-programming</a></p> <p>As you can see, for multi-image builds (which all builds for nrf9160_pca10090ns are as it includes the Secure Partition Manager), you are only given the option of merged.hex.</p> <p>As you have noticed, zephyr.elf is built as part of the merged.hex target. What is happening is that each image gets built as an elf file, which is converted to a hex file. All these hex files then get merged into merged.hex. You can find the elf files of the other images here: &lt;your build folder&gt;/&lt;image name (e.g. spm, mcuboot)&gt;/zephyr/zephyr.elf</p> <p>Best regards,</p> <p>Didrik</p><div style="clear:both;"></div>
