https://test-devzone.nordicsemi.com/f/nordic-q-a/87238/nrf51-won-t-boot-after-ram-adjustmentI am trying to program my nRF51 QFAC, but it tells me to adjust my linker settings. I am using the SDK 12.3 and the softdevice 130 2.0.1. However, after I apply the proposed ram origin and size, the chip just doesn&#39;t boot or give me any log outputen-USTelligent Community 13 Non-ProductionWed, 11 May 2022 07:57:14 GMThttps://test-devzone.nordicsemi.com/thread/367321?ContentTypeID=1Wed, 11 May 2022 07:57:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:feff8e74-8ef5-479d-bcd1-dd60dd22bac7user82185<p>Switching back go&nbsp;gcc-arm-none-eabi-4_9-2015q3 fixed my issues.</p><div style="clear:both;"></div>https://test-devzone.nordicsemi.com/thread/364647?ContentTypeID=1Mon, 25 Apr 2022 09:19:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e686041c-694a-458d-a20a-579650e3169fuser75734<p>Hi</p> <p>What IDE are you using for development? You can check out this guide on how to adjust RAM and Flash memory correctly for your device. If it does indeed not respond after adjusting, that might point towards the application being larger than the amount of memory available on your device, in which case you will have to either optimize it, cut some features from your project, or move to a SoC with more memory available. Are you able to see the size of the application and SoftDevice when building the project?</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
