MK60FX512VLQ15读写内部EEPROM问题

retome · 发表于 2014-12-28 12:54:34

好像照搬了论坛那个还是不行啊，那个好像不适用于FX512LQ15 读取地址时提示串口调试提示：BusFault Interrupt0 BusFault Interrupt0

谢谢！谁有读写成功的，麻烦提供参考一下！

具体flexNVM的分区指令，你要查看K60 150M的用户手册。
还有就是要保证你本身的基础工程要正确。
你现在分区命令用的是什么？

你现在 ...

flexmem_ee32bit_write(0x14000006,0x000123);
仿真运行完到这个的时候就会串口调试输出:BusFault Interrupt0 BusFault Interrupt0
再运行这个 printf("%d\n",flex_ee32bit_read(0x14000006)); 居然输出是-625435；居然是负数！
