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; You can change the memory allocation by editing RAM and Flash defines. 50; Your changes must be aligned with the corresponding defines for CM0+ core in 'xx_cm0plus.scat', 51; where 'xx' is the device group; for example, 'cyb06xx7_cm0plus.scat'. 52; RAM 53#define RAM_START 0x08000800 54#define RAM_SIZE 0x0001F800 55; Flash 56#define FLASH_START 0x10000000 57#define FLASH_SIZE 0x00030000 58 59; The size of the stack section at the end of CM4 SRAM 60#define STACK_SIZE 0x00001000 61 62; The size of the MCU boot header area at the start of FLASH 63#define BOOT_HEADER_SIZE 0x00000400 64 65; The size of the Cortex-M0+ application image (including MCU boot header area) 66#define FLASH_CM0P_SIZE 0x10000 67 68 69; The following defines describe device specific memory regions and must not be changed. 70; External memory 71#define XIP_START 0x18000000 72#define XIP_SIZE 0x08000000 73 74 75; Cortex-M0+ application flash image area 76LR_IROM (FLASH_START + BOOT_HEADER_SIZE) (FLASH_CM0P_SIZE - BOOT_HEADER_SIZE) 77{ 78 .cy_m0p_image +0 79 { 80 * (.cy_m0p_image) 81 } 82} 83 84; Cortex-M4 application flash area 85LR_IROM1 (FLASH_START + FLASH_CM0P_SIZE) (FLASH_SIZE - FLASH_CM0P_SIZE) 86{ 87 ER_FLASH_VECTORS +0 88 { 89 * (RESET, +FIRST) 90 } 91 92 ER_FLASH_CODE +0 FIXED 93 { 94 * (InRoot$$Sections) 95 * (+RO) 96 } 97 98 ER_RAM_VECTORS RAM_START UNINIT 99 { 100 * (RESET_RAM, +FIRST) 101 } 102 103 RW_RAM_DATA +0 104 { 105 * (.cy_ramfunc) 106 * (+RW, +ZI) 107 } 108 109 ; Place variables in the section that should not be initialized during the 110 ; device startup. 111 RW_IRAM1 +0 UNINIT 112 { 113 * (.noinit) 114 * (.bss.noinit) 115 } 116 117 ; Application heap area (HEAP) 118 ARM_LIB_HEAP +0 EMPTY ((RAM_START+RAM_SIZE)-AlignExpr(ImageLimit(RW_IRAM1), 8)-STACK_SIZE) 119 { 120 } 121 122 ; Stack region growing down 123 ARM_LIB_STACK (RAM_START+RAM_SIZE) EMPTY -STACK_SIZE 124 { 125 } 126 127 ; Used for the digital signature of the secure application and the 128 ; Bootloader SDK application.
