Где можно почитать /окультуриться по поводу правил написания файлов конфигураций под проект? к примеру в атолике есть STM32F334C8_FLASH.ld с ** ** (c)Copyright Atollic AB. ** You may use this file as-is or modify it according to the needs of your ** project. This file may only be built (assembled or compiled and linked) ** using the Atollic TrueSTUDIO(R) product.
