完蛋了，早上把MINI2440USB给烧坏了，检查不出来！高手给个建议！正在学习USB摄像头，屏幕显示正常。

这块被烧坏了，~~~~(>_<)~~~~
检查r23 r24 r27 r28 电阻分别为22 22 15k 10k
是否有影响？
初始电平为OV,接上USB后R24两端电平为3V，其余为0v

把nand中的bootloader改为supervivi试试

刚把电阻r27 r28 都换成新的电阻10K，问题依然
把nand中的bootloader改为supervivi试试？不知道是要怎么改法？麻烦指点下，谢谢

从nor启动，输入“v"下载，选择烧写supervivi

刚使用USB下载也不行了，DNW联不上，找不到设备，设备管理器里面也没有

是否还要重新用JTAG烧vivi?

DNW连接上了，重新F X V K Y 一次，B启动后，问题依然，

用DNW那个端口的USB测试能行？

看看USB_EN有没有使能，连通后一般是高电平

USB_EN电平一直是3.2V，
想问下改动PDN0 PDP0为DN1 DP1，对应底层的驱动是否还可以用？
就是USB接口0的驱动，是否适用于USB接口1上，谢谢

下午改动了下，驱动不了接口1上的USB
