在M451中，使用U盘更新APROM

只看该作者 · 2015-9-24 11:32

感谢CYTseng提供。
CONFIG请设成BOOT IN "LDROM with IAP".
使用在KEIL编译後下载代码至M451即可。在U盘中，要更新的BIN档请改成AP.BIN即可。

U盘的接口程序如何写的啊，我要学学了，这个好神奇的。

IAP程序先读取U盘数据，然后确认固件后，读取写入到Flash

有了这个可以拷贝进去就行了

不知道原理是什么，要不停扫描优盘内容吗？

用U盘更新APROM，是一个很不错的想法啊

NXP的ARM就是这样

是启动设置成LDROM 含IAP功能吧??然后把程序烧写到APROM吧?烧写到LDROM说程序太大,
U盘更目录下有个IP.bin程序.插U盘上电后,观看串口输出的信息,无任何输出.
再把启动塞罕至成APROM,重启后,可以看到串口输出

U盘也可以，这个方法比较好，不需要单独搞烧录软件了。
