K20 USB device MSD bootloader

最近搞了一个基于TWR-K20D50M的的USB MSD device bootloader, 可以打开文件夹CW中的K20D5下的.project来查看。

在原始的MSD的基础上移植了FAT过来。

其他IAR和Kinetis的其他chip没有测试,如果需要使用,一个是新增相关头文件,二是在bootloader.h中修改相应的MCU_K20D50M定义下的flash及ram配置

Nice, now we can design a K20 board with your bootloader and download OpenSDA applications used in FRDM-KL25Z. Can I say that?

I also have a document USB MSC device bootloader revision for FRDM-KL25Z (IAR).

Hi, Mr You.

Do you have any idea why bootloader works in debugger but failed in off-debugger run time? Please check this thread. https://community.freescale.com/message/365883#365883

Hi Dawei

請問這個MSD可以使用在MK20DN512xxx10上嗎?

可以的,只是主频不一样而已。

但是现在有sdk,如果是全新开发的项目建议从sdk走。
