如题。我修改内核mach-davinci/usb.c的musb_config无效,内核启动依然还是musb-hdrc: ConfigData=0x06 (UTMI-8, dyn FIFOs, SoftConn);直接通过musb_writeb配置MUSB_CONFIGDATA还是无效。请问如何配置,才能支持HB-ISO Rx, HB-ISO Tx 来支持usb的同步模式

你好,
我在DM365的数据手册里面看到了下面的内容:
The USB2.0 peripheral does not support the following features:
• On-chip charge pump
• High bandwidth ISO mode is not supported (triple buffering)
