commit e5f7579c884ea7003cc68c3eaf34a8f86cc66f5c Author: Jerzy Kasenberg <[email protected]> AuthorDate: Wed Oct 14 22:33:41 2026 +0200 targets/auracast_usb: Sync MCU linker script with mynewt-core The target uses a copy of nRF5340 MCU linker script from mynewt-core that places LC3, libsamplerate, libm and audio_usb code in RAM. The copy got out of date with core and the application no longer links (undefined static_conf_handlers) since link tables are missing. Regenerate the script from current mynewt-core version, which brings in link tables (that now also provide net core image section), NSC region and .noinit section, and keep only auracast specific code placement on top of it.
