#! armclang -E --target=arm-arm-none-eabi -x c -mcpu=cortex-m4 ; The first line specifies a preprocessor command that the linker invokes ; to pass a scatter file through a C preprocessor. ;******************************************************************************* ;* \file cy8c6xx7_cm4.sct ;* \version 2.91 ;* ;* Linker file for the ARMCC. ;* ;* 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 location 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 the warnings ;* during the build process: L6314W (no section matches pattern) and/or L6329W ;* (pattern only matches removed unused sections). In your project, you can ;* suppress the warning by passing the "--diag_suppress=L6314W,L6329W" option to ;* the linker, 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. ;******************************************************************************/ ; The defines below describe the location and size of blocks of memory in the target. ; Use these defines to specify the memory regions available for allocation. ; The following defines control RAM and flash memory allocation for the CM4 core. ; Note that 2176 bytes of RAM (at the end of the SRAM) are reserved for system use. ; Using this memory region for other purposes will lead to unexpected behavior. ; RAM #define RAM_START 0x08000000 #define RAM_SIZE 0x00047780 ; Flash #define FLASH_START 0x10000000 #define FLASH_SIZE 0x00100000 ; The size of the stack section at the end of CM4 SRAM #define STACK_SIZE 0x00001000 ; The following defines describe a 32K flash region used for EEPROM emulation. ; This region can also be used as the general purpose flash. ; You can assign sections to this memory region for only one of the cores. ; Note some middleware (e.g. BLE, Emulated EEPROM) can place their data into this memory region. ; Therefore, repurposing this memory region will prevent such middleware from operation. #define EM_EEPROM_START 0x14000000 #define EM_EEPROM_SIZE 0x8000 ; The following defines describe device specific memory regions and must not be changed. ; Supervisory flash: User data #define SFLASH_USER_DATA_START 0x16000800 #define SFLASH_USER_DATA_SIZE 0x00000800 ; Supervisory flash: Normal Access Restrictions (NAR) #define SFLASH_NAR_START 0x16001A00 #define SFLASH_NAR_SIZE 0x00000200 ; Supervisory flash: Public Key #define SFLASH_PUBLIC_KEY_START 0x16005A00 #define SFLASH_PUBLIC_KEY_SIZE 0x00000C00 ; Supervisory flash: Table of Content # 2 #define SFLASH_TOC_2_START 0x16007C00 #define SFLASH_TOC_2_SIZE 0x00000200 ; Supervisory flash: Table of Content # 2 Copy #define SFLASH_RTOC_2_START 0x16007E00 #define SFLASH_RTOC_2_SIZE 0x00000200 ; External memory #define XIP_START 0x18000000 #define XIP_SIZE 0x08000000 ; eFuse #define EFUSE_START 0x90700000 #define EFUSE_SIZE 0x100000 ; Cortex-M4 application flash area LR_IROM1 FLASH_START FLASH_SIZE { ER_FLASH_VECTORS +0 { * (RESET, +FIRST) } ER_FLASH_CODE +0 FIXED { * (InRoot$$Sections) * (+RO) } ER_RAM_VECTORS RAM_START UNINIT { * (RESET_RAM, +FIRST) } RW_RAM_DATA +0 { * (.cy_ramfunc) * (+RW, +ZI) } ; Place variables in the section that should not be initialized during the ; device startup.
