Your project may not use every 20;* section defined in the linker files. In that case you may see the warnings 21;* during the build process: L6314W (no section matches pattern) and/or L6329W 22;* (pattern only matches removed unused sections). In your project, you can 23;* suppress the warning by passing the "--diag_suppress=L6314W,L6329W" option to 24;* the linker, simply comment out or remove the relevant code in the linker 25;* file. 26;* 27;******************************************************************************* 28;* \copyright 29;* Copyright 2016-2021 Cypress Semiconductor Corporation 30;* SPDX-License-Identifier: Apache-2.0 31;* 32;* Licensed under the Apache License, Version 2.0 (the "License"); 33;* you may not use this file except in compliance with the License. 34;* You may obtain a copy of the License at 35;* 36;* http://www.apache.org/licenses/LICENSE-2.0 37;* 38;* Unless required by applicable law or agreed to in writing, software 39;* distributed under the License is distributed on an "AS IS" BASIS, 40;* WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 41;* See the License for the specific language governing permissions and 42;* limitations under the License. 43;******************************************************************************/ 44 45; The defines below describe the location and size of blocks of memory in the target. 46; Use these defines to specify the memory regions available for allocation. 47 48; The following defines control RAM and flash memory allocation for the CM4 core. 49; RAM 50#define RAM_START 0x08001800 51#define RAM_SIZE 0x0001E800 52; Flash 53#define FLASH_START 0x10020000 54#define FLASH_SIZE 0x00020000 55 56; The size of the stack section at the end of CM4 SRAM 57#define STACK_SIZE 0x00001000 58 59; The size of the MCU boot header area at the start of FLASH 60#define BOOT_HEADER_SIZE 0x00000400 61 62 63; The following defines describe device specific memory regions and must not be changed. 64; External memory 65#define XIP_START 0x18000000 66#define XIP_SIZE 0x08000000 67 68 69 70; Cortex-M4 application flash area 71LR_IROM1 (FLASH_START + BOOT_HEADER_SIZE) (FLASH_SIZE - BOOT_HEADER_SIZE) 72{ 73 ER_FLASH_VECTORS +0 74 { 75 * (RESET, +FIRST) 76 } 77 78 ER_FLASH_CODE +0 FIXED 79 { 80 * (InRoot$$Sections) 81 * (+RO) 82 } 83 84 ER_RAM_VECTORS RAM_START UNINIT 85 { 86 * (RESET_RAM, +FIRST) 87 } 88 89 RW_RAM_DATA +0 90 { 91 * (.cy_ramfunc) 92 * (+RW, +ZI) 93 } 94 95 ; Place variables in the section that should not be initialized during the 96 ; device startup. 97 RW_IRAM1 +0 UNINIT 98 { 99 * (.noinit) 100 * (.bss.noinit) 101 } 102 103 ; Application heap area (HEAP) 104 ARM_LIB_HEAP +0 EMPTY ((RAM_START+RAM_SIZE)-AlignExpr(ImageLimit(RW_IRAM1), 8)-STACK_SIZE) 105 { 106 } 107 108 ; Stack region growing down 109 ARM_LIB_STACK (RAM_START+RAM_SIZE) EMPTY -STACK_SIZE 110 { 111 } 112 113 ; Used for the digital signature of the secure application and the 114 ; Bootloader SDK application.
