我手上的板子是 hpm6750evkmini.yaml ,带了 16MB的外置 SDDRAM。用起来有个问题, 1)如果使用 -DCMAKE_BUILD_TYPE=debug_flash_sdram_xip,则每次烧写到NOR FLASH 太慢,等待消耗太长时间。 2)如果使用 -DCMAKE_BUILD_TYPE=debug,则镜像写到 ILM中,但又受限与 ILM的大小。 因此手撸了一个将镜像烧写到 SDRAM 的配置,支持 make flash 直接烧写到 FLASH 或者 SDRAM 中。以 hello_world为例,需要改动的文件 1) soc/HPM6750/toolchains/gcc/ram.ld 此文件需要调整各个 section 的布局(即加载地址 LMA 和 执行地址VMA)。 文件在文末提供,复制并覆盖到 ram.ld即可。 2) samples/hello_world/CMakeLists.txt 此文件需要加上一些代码以支持 make flash,完整文件在文末提供,复制并覆盖到 hello_world/CMakeLists.txt 文件即可。 一、烧写到 SDRAM 中 $ cd hello_world/build $ cmake -DCMAKE_BUILD_TYPE=debug -DBOARD=hpm6750evkmini .. $ make flash 二、烧写到 FLASH 中 $ cd hello_world/build $ cmake -DCMAKE_BUILD_TYPE=debug_flash_sdram_xip -DBOARD=hpm6750evkmini .. $ make flash 三、在 SDRAM 中调试 1)先编译 $ cd hello_world/build $ cmake -DCMAKE_BUILD_TYPE=debug_flash_sdram_xip -DBOARD=hpm6750evkmini .. $ make 2)启动 openocd $ openocd -f ${HPM_SDK_BASE}/boards/openocd/probes/ft2232.cfg -f ${HPM_SDK_BASE}/boards/openocd/soc/hpm6750-single-core.cfg -f ${HPM_SDK_BASE}/boards/openocd/boards/hpm6750evkmini.cfg 3)新开一个 终端窗口进行调试 $ cd hello_world/build $ riscv32-unknown-elf-gdb output/demo.elf > target remote localhost:3333 > monitor reset init > load > b main > c --------------------------- 以下为 hello_world/CMakeLists.txt ---------------------------------- # Copyright (c) 2021 HPMicro # SPDX-License-Identifier: BSD-3-Clause cmake_minimum_required(VERSION 3.13) set(CMAKE_EXPORT_COMPILE_COMMANDS ON) find_package(hpm-sdk REQUIRED HINTS $ENV{HPM_SDK_BASE}) project(hello_world) SET(OPENOCD_DRV $ENV{HPM_SDK_BASE}/boards/openocd/probes/ft2232.cfg) SET(OPENOCD_SOC $ENV{HPM_SDK_BASE}/boards/openocd/soc/hpm6750-single-core.cfg) SET(OPENOCD_BRD $ENV{HPM_SDK_BASE}/boards/openocd/boards/hpm6750evkmini.cfg) SET(ELF_FILE ${PROJECT_BINARY_DIR}/output/${APP_NAME}.elf) SET(BIN_FILE ${PROJECT_BINARY_DIR}/output/${APP_NAME}.bin) SET(HEX_FILE ${PROJECT_BINARY_DIR}/output/${APP_NAME}.hex) message(STATUS "elf: ${ELF_FILE}") message(STATUS "bin: ${BIN_FILE}") message(STATUS "hex: ${HEX_FILE}") string(TOLOWER ${CMAKE_BUILD_TYPE} build_type) string(FIND ${build_type} "flash" found) if (${found} GREATER_EQUAL 0) message(STATUS "run on flash") add_custom_target(flash COMMAND "${CROSS_COMPILE}objcopy" -O ihex -S ${ELF_FILE} ${HEX_FILE} COMMAND openocd -f ${OPENOCD_DRV} -f ${OPENOCD_SOC} -f ${OPENOCD_BRD} -c 'init' -c 'reset init' -c 'program ${HEX_FILE} verify' -c 'reset' -c 'shutdown' DEPENDS ${APP_ELF_NAME} ) else() message(STATUS "run on ram") #sdk_compile_definitions(-DFLASH_XIP=1 -DINIT_EXT_RAM_FOR_DATA=1) sdk_compile_definitions(-DFLASH_XIP=1) add_custom_target(flash COMMAND openocd -f ${OPENOCD_DRV} -f ${OPENOCD_SOC} -f ${OPENOCD_BRD} -c 'init' -c 'reset init' -c 'load_image ${BIN_FILE} 0x40c00000' -c 'resume 0x40c00000' -c 'shutdown' DEPENDS ${APP_ELF_NAME} ) endif() sdk_compile_definitions(-DBOARD_SHOW_CLOCK=1 -DBOARD_SHOW_BANNER=1) sdk_app_src(src/hello_world.c) generate_ses_project() --------------------------- 以下为 soc/HPM6750/toolchains/gcc/ram.ld ---------------------------------- /* * Copyright (c) 2021-2022 HPMicro * SPDX-License-Identifier: BSD-3-Clause */ ENTRY(_start) STACK_SIZE = DEFINED(_stack_size) ?
