https://devzone.nordicsemi.com/f/nordic-q-a/42668/creation-of-the-position-independent-firmwareHello! I am implementing a custom OTA procedure for the NRF52840 development board and I need to be able to load the firmware from several predefined positions in the flash. I&#39;ve already implemented the bootloader that is able to load firmwares fromen-USTelligent Community 13Fri, 18 Jan 2019 11:46:22 GMThttps://devzone.nordicsemi.com/thread/166448?ContentTypeID=1Fri, 18 Jan 2019 11:46:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9107b470-0716-4e55-830c-ab4c01a3d9d1Einar Thorsrud<p>Hi,</p> <p>This question is very similar to a question I recently got via a different channel, so I believe I am already discussing this topic with one of your colleagues.</p> <p>Generally, we do not recommend position independent firmware, nor do we have any instructions or guidance.
