AM335x(TQ335x)学习笔记——USB驱动移植

关于AM335x来讲,TI保护的USB驱动现已十分完善了,本文称之为移植,实际上仅仅是装备内核选项使能USB HOST/OTG功用。废话少说,直接着手敞开AM335x的USB驱动装备项。

Step1. 装备内核支撑USB

默许的装备项没有装备USB相关的选项,可是DTS现已装备好了,咱们不需求对DTS作任何修正,具体的内核装备项如下:

  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. 编译内核

编译内核的指令如下:

  1. makeARCH=armCROSS_COMPILE=arm-linux-gnueabi–j8

Step3.测验

用新编译好的内核发动开发板,能够看到如下Log:

结尾是拔插U盘的效果。

Step4. 装备其它USB设备驱动

假如需求装备其它USB设备驱动能够持续在menuconfig装备列表中进行装备,这儿就不逐个介绍了。

注:

不知道是我的开发板硬件问题仍是其它问题,我自己移植的Linux-3.17.2只要中心的一个USB端口可用,别的两个USB端口没有任何效果。运用官方供给的内核镜像也存在这样的问题,下周一跟天嵌售后承认下此问题。假如看到本文的朋友手头上也有TQ3358开发板,请帮助测验下,多谢。
