			對(duì)于AM335x來講，TI維護(hù)的USB驅(qū)動(dòng)已經(jīng)非常完善了，本文稱之為移植，實(shí)際上僅僅是配置內(nèi)核選項(xiàng)使能USB HOST/OTG功能。廢話少說，直接動(dòng)手開啟AM335x的USB驅(qū)動(dòng)配置項(xiàng)。
          Step1. 配置內(nèi)核支持USB
          本文引用地址：http://www.ex-cimer.com/article/201611/322825.htm
          默認(rèn)的配置項(xiàng)沒有配置USB相關(guān)的選項(xiàng)，但是DTS已經(jīng)配置好了，我們不需要對(duì)DTS作任何修改，詳細(xì)的內(nèi)核配置項(xiàng)如下：
          1. DeviceDrivers--->
          2. [*]USBsupport--->
          3. [*]OTGsupport
          4. <*>EHCIHCD(USB2.0)support
          5. [*]ImprovedTransactionTranslatorscheduling(NEW)
          6. <*>EHCIsupportforOMAP3andlaterchips(NEW)
          7. <*>OHCIHCD(USB1.1)support
          8. <*>OHCIsupportforOMAP3andlaterchips(NEW)
          9. <*>InventraHighspeedDualRoleController(TI,ADI,...)
          10. MUSBModeSelection(DualRolemode)--->
          11. <*>PlatformGlueLayer(TIDSPSplatforms)--->
          12. MUSBDMAmode(DisableDMA(alwaysusePIO))--->
          Step2. 編譯內(nèi)核
          編譯內(nèi)核的指令如下：
          1. makeARCH=armCROSS_COMPILE=arm-linux-gnueabi--j8
          Step3.測試
          用新編譯好的內(nèi)核啟動(dòng)開發(fā)板，可以看到如下Log：

          Step4. 配置其它USB設(shè)備驅(qū)動(dòng)
          如果需要配置其它USB設(shè)備驅(qū)動(dòng)可以繼續(xù)在menuconfig配置列表中進(jìn)行配置，這里就不一一介紹了。
          注：
          不知道是我的開發(fā)板硬件問題還是其它問題，我自己移植的Linux-3.17.2只有中間的一個(gè)USB端口可用，另外兩個(gè)USB端口沒有任何作用。使用官方提供的內(nèi)核鏡像也存在這樣的問題，下周一跟天嵌售后確認(rèn)下此問題。如果看到本文的朋友手頭上也有TQ3358開發(fā)板，請(qǐng)幫忙測試下，多謝。
