/******************************************************************************* * \file cy8c6xxa_cm0plus.icf * \version 2.91 * * Linker file for the IAR compiler. * * The main purpose of the linker script is to describe how the sections in the * input files should be mapped into the output file, and to control the memory * layout of the output file. * * \note The entry point is fixed and starts at 0x10000000. The valid application * image should be placed there. * * \note The linker files included with the PDL template projects must be generic * and handle all common use cases. Your project may not use every section * defined in the linker files. In that case you may see warnings during the * build process. In your project, you can simply comment out or remove the * relevant code in the linker file. * ******************************************************************************** * \copyright * Copyright 2016-2021 Cypress Semiconductor Corporation * SPDX-License-Identifier: Apache-2.0 * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. *******************************************************************************/ /*###ICF### Section handled by ICF editor, don't touch! ****/ /*-Editor annotation file-*/ /* IcfEditorFile="$TOOLKIT_DIR$\config\ide\IcfEditor\cortex_v1_4.xml" */ /*-Specials-*/ define symbol __ICFEDIT_intvec_start__ = 0x00000000; /*-Sizes-*/ if (!isdefinedsymbol(__STACK_SIZE)) { define symbol __ICFEDIT_size_cstack__ = 0x1000; } else { define symbol __ICFEDIT_size_cstack__ = __STACK_SIZE; } define symbol __ICFEDIT_size_proc_stack__ = 0x0; /* Defines the minimum heap size.
