eclipse环境下STM32调用jlink如何实现解除读写保护？
本帖最后由 lindahnu 于 2023-12-29 15:38 编辑之前发过一个帖子，后来找到MDK示例工程参照就直接点击下载即可
STM32G0x0_OPT.s和STM32G0x0_OPT.FLM如何在MDK里使用实现解除读写保护功能 - 开发环境 - 硬汉嵌入式论坛 - Powered by Discuz! (armbbs.cn)
想参照MDK在eclipse上实现相同的功能，改了ld文件，工程只添加一个.c定义一个数组
const unsigned char OPTData = {0xAA,0x10,0x0F,0x08,0x00,0xff,0x00,0xff,
0x00,0xff,0x00,0xff};

/*
ENTRY(Reset_Handler)
*/
/* Highest address of the user mode stack */
_estack = 0x20002000; /* end of RAM */
/* Generate a link error if heap and stack don't fit into RAM */
_Min_Heap_Size = 0x200; /* required amount of heap*/
_Min_Stack_Size = 0x400; /* required amount of stack */
/* Specify the memory areas */
MEMORY
{
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 8K
FLASH (rx) : ORIGIN = 0x1FFF7800, LENGTH = 12

配置外部工具调用jlink.txt，下载没有效果，不生效

用JFlash怎么实现？把MDK生成的hex文件拖进去就能自动识别下载吗？怎么知道用哪个FLM？工程界面显示如下：
