以下命令在所有RTOS平台（MELIS/FREERTOS）都可以使用 通过menuconfig打开usb模块功能 RTOS通过usb命令集成了测试用例。通过如下命令即可显示支持的功能： <span class="hljs-comment" style="box-sizing: border-box; color: rgb(188, 148, 88); font-style: italic;">//输入如下命令</span>
msh />usb
Usage:
usb hci {-i|-r} [<port>]
usb udc {-i|-r} [<port>]
usb phy_range {-s|-g} {<port>} [<phyrange>]
usb ed_test {<port>} {<type>}
usb debug {<status>}

OTG0 phy range
phy_range = 0xa07, details:
bit[12] = 0x0, mode iref-1 vref-0
<span class="hljs-section" style="box-sizing: border-box; color: rgb(255, 198, 109);">bit[11:9] = 0x5, rise time(all usb)</span>

USB0较为特殊，host和device的参数是分开调整的，注意打印，例如上述例子中，“OTG0 phy range”表示目前处于device模式，显示的是device端的phy range。 phy_range就是目前的值，调整参数可以在此基础上进行调整，具体含义参考上面打印中的提示。 usb phy_range -s <span class="hljs-number" style="box-sizing: border-box; color: rgb(165, 194, 97);">0</span> <span class="hljs-number" style="box-sizing: border-box; color: rgb(165, 194, 97);">0xa08</span>
…
OTG0 phy range
phy_range config <span class="hljs-keyword" style="box-sizing: border-box; color: rgb(194, 98, 48);">in</span> vref mode success!
同理，“OTG0 phy range”表示目前处于device模式，设置的是device端的phy range。 ed test测试模式设置命令形式：usb ed_test {<port>} {<type>} <span class="hljs-attribute" style="box-sizing: border-box; color: rgb(205, 168, 105);">usb</span> ed_test <span class="hljs-number" style="box-sizing: border-box; color: rgb(165, 194, 97);">1</span> test_j_state
usb debug功能启停命令形式：usb debug {<status>} <span class="hljs-attribute" style="box-sizing: border-box; color: rgb(205, 168, 105);">usb</span> <span class="hljs-literal" style="box-sizing: border-box;">debug</span> <span class="hljs-number" style="box-sizing: border-box; color: rgb(165, 194, 97);">1</span>
