买了一块开发板（简称‘板1’），上面有一个USB读卡的程序，可以正常读TF卡，现在我想把该程序用到另外一个板子上（简称‘板2’），但是程序下载不了，板2可以正常的跑自己写的程序。两个板子的区别是：板1用的芯片是stm32f103vet6，板2用的芯片是stm32f103zet6，板1是通过JTAG下载，板2通过SWD方式下载，其他的地方没有太大的差别。
下载时会先弹出一个提示框，提示没有发现JTAG，然后再弹出提示说下载失败，编译信息区给出提示如下：
Load "E:\\STM32F103VET\\程序\\STM32-SD卡U盘例程\\Project\\Mass_Storage\\RVMDK\\stm32-fd-sd-usb.AXF"
Set JLink Project File to "E:\STM32F103VET\程序\STM32-SD卡U盘例程\Project\Mass_Storage\RVMDK\JLinkSettings.ini"
