TI中文支持网问题一：显示烧写内核 davinci_interrupt 368: VBUS error workaround (delay coming) *****
ttyUSB* 只有4个。 如果将下图的 * 改成 M 则有 6个 ttyUSB* 这样就相当于不支持CDC驱动了，不符合要求了。
我查了相关资料和硬件给的原理图，发现硬件设计是这样的
但是我查看了，TI官方给出的方案是这样的。
所以我怀疑是不是应该加一个电容比较好，还有就是我发现核心板VBUS是直接接5V供电
执行命令 ls –l /sys/bus/usb/drivers/option/***/
4个ttyUSB 和 6个ttyUSB 比较

Chris Meng：
你好，
你能否用示波器测量一下VBUS上的电压，看是否有不正常的跌落？这样可以确认是否VBUS电流不够电压被拉低导致的问题。
JUKE CHEN：
回复 Chris Meng:
我们硬件工程师，vbus直接接的5V，我用示波器测试了一下，跌落是有的。 如果硬件不能改了，软件应该怎么改程序呢？
Chris Meng：
回复 JUKE CHEN:
你好，
软件上没有很好的方法。
建议硬件上涨VBUS上加一个大电容，减少VBUS的跌落。
JUKE CHEN：
回复 Chris Meng:
你确定是硬件的问题吗？ 那硬件除了，需要加电容，还有什么需要完善的？
JUKE CHEN：
回复 Chris Meng:
还有就是这个 VBUS标准电压应该是多少？
Chris Meng：
回复 JUKE CHEN:
你好，
DM36x的数据手册里面有如下描述：
USB_VBUS
This pin is used by the USB Controller to detect apresence of 5V power (4.4V is the threshold) on theUSB_VBUS line for normal operation. This power issourced by the USB Component that is assuming therole of a Host. In other words, the power on theUSB_VBUS line is not sourced by the Device. FromDM365 perspective, when operating as a Host, itensures that the external power supply that theDM365 has sourced is within the required voltagelevel (>= 4.4V) and when DM365 is operating as aDevice, the presence of a 5V power on the VBUSLine is used to signify the presence of an externalHost.
JUKE CHEN：
回复 Chris Meng:
亲 davinci_interrupt 368: VBUS error workaround (delay coming) 这个问题，我搞了一个月了，还是没有进展啊。
你能再帮我，看看，哪里有问题了吗？
guangyun wang：
我用的bbb板子，sdk是《ti-sdk-am335x-evm-06.00.00.00-Linux-x86-Install》，也遇到了移植系统后，卡在 ti81xx_interrupt 1146: VBUS error workaround (delay coming)这了，反复打印这条信息。
请问，你最后是怎么解决的啊？
