AM335x(TQ335x)学习笔记——Nand&&网卡驱动移植

作者： 时间：2016-11-28 来源：网络 收藏
移植完成声卡驱动之后本想再接再励，移植网卡驱动，但没想到的是TI维护的内核太健壮，移植网卡驱动跟之前移植按键驱动一样简单，Nand驱动也是如此，于是，本人将Nand和网卡放在同一篇文章中介绍。介绍之前先感慨一下：TI的维护的内核真的很健壮，DTS真的很强大。

1. Nand驱动移植

本文引用地址：//m.amcfsurvey.com/article/201611/322824.htm

阅读TQ335x的原理图可知，TQ335x的Nand连接到了GPMC上，且与DTS中默认的配置吻合，此处不做任何修改，详情如下：

  1. nandflash_pins_s0:nandflash_pins_s0{
  2. pinctrl-single,pins=<
  3. 0x0(PIN_INPUT_PULLUP|MUX_MODE0)/*gpmc_ad0.gpmc_ad0*/
  4. 0x4(PIN_INPUT_PULLUP|MUX_MODE0)/*gpmc_ad1.gpmc_ad1*/
  5. 0x8(PIN_INPUT_PULLUP|MUX_MODE0)/*gpmc_ad2.gpmc_ad2*/
  6. 0xc(PIN_INPUT_PULLUP|MUX_MODE0)/*gpmc_ad3.gpmc_ad3*/
  7. 0x10(PIN_INPUT_PULLUP|MUX_MODE0)/*gpmc_ad4.gpmc_ad4*/
  8. 0x14(PIN_INPUT_PULLUP|MUX_MODE0)/*gpmc_ad5.gpmc_ad5*/
  9. 0x18(PIN_INPUT_PULLUP|MUX_MODE0)/*gpmc_ad6.gpmc_ad6*/
  10. 0x1c(PIN_INPUT_PULLUP|MUX_MODE0)/*gpmc_ad7.gpmc_ad7*/
  11. 0x70(PIN_INPUT_PULLUP|MUX_MODE0)/*gpmc_wait0.gpmc_wait0*/
  12. 0x74(PIN_INPUT_PULLUP|MUX_MODE7)/*gpmc_wpn.gpio0_30*/
  13. 0x7c(PIN_OUTPUT|MUX_MODE0)/*gpmc_csn0.gpmc_csn0*/
  14. 0x90(PIN_OUTPUT|MUX_MODE0)/*gpmc_advn_ale.gpmc_advn_ale*/
  15. 0x94(PIN_OUTPUT|MUX_MODE0)/*gpmc_oen_ren.gpmc_oen_ren*/
  16. 0x98(PIN_OUTPUT|MUX_MODE0)/*gpmc_wen.gpmc_wen*/
  17. 0x9c(PIN_OUTPUT|MUX_MODE0)/*gpmc_be0n_cle.gpmc_be0n_cle*/
  18. >;
  19. };

直接编译内核，并放到开发板上运行。这时我们会发现内核可以识别Nand，但是因为没有开启OMAP的BCH功能会报一处错误。开启该配置项的方法如下：

  1. DeviceDrivers--->
  2. <*>MemoryTechnologyDevice(MTD)support--->
  3. <*>NANDDeviceSupport--->
  4. <*>SupporthardwarebasedBCHerrorcorrection
保存配置并退出menuconfig，然后重新编译内核并放到开发板上运行，此时会发现内核已经可以正常识别Nand了，完整的启动Log会在文章末尾给出。从这里可以看出，TI的内核维护的真的很不错，比以前移植三星芯片时省事很多。

2. 网卡驱动移植

进行网卡驱动移植的方法与进行Nand驱动移植的方法相同，逻辑上讲，先应该去确认下网卡的引脚连接并在DTS中进行相应的pinmux设置，但是，移植完Nand后查看内核的启动Log可知，网卡已经正常识别了，因此，可以直接执行指令：

  1. udhcpc
来动态获取ip（需要将开发板通过网线连接到路由器并开启路由器的DHCP功能，默认一般是开启的），会发现开发板能够从路由器分配到IP，但是没有分配DNS，这是因为我们只做文件系统时没有进行dhcp的设置。设置方法很简单，将busybox中的examples/udhcp/simple.script拷贝到根文件系统的usr/share/udhcpc/目录下，并改名为default.script即可。然后重新执行：
  1. udhcpc

会发现开发板可以正常获取到IP和DNS，但是仍有一处错误，详细如下：

  1. @tq335x#udhcpc
  2. udhcpc(v1.22.1)started
  3. SettingIPaddress0.0.0.0oneth0
  4. [11.489311]neteth0:initializingcpswversion1.12(0)
  5. [11.576237]neteth0:phyfound:idis:0x1cc915
  6. [11.581418]libphy:PHY4a101000.mdio:01notfound
  7. [11.586480]neteth0:phy4a101000.mdio:01notfoundonslave1

  16. Addingrouter192.168.0.1
  17. Recreating/etc/resolv.conf
  18. AddingDNSserver10.0.0.1
参考TI官网提供的evm开发板的dts，本文对tq335x.dts做如下修改：
  1. &mac{
  2. slaves=<1>;
  3. pinctrl-names="default","sleep";
  4. pinctrl-0=<&cpsw_default>;
  5. pinctrl-1=<&cpsw_sleep>;
  6. status="okay";
  7. };
然后删除以下节点：
  1. &cpsw_emac1{
  2. phy_id=<&davinci_mdio>,<1>;
  3. phy-mode="rgmii-txid";
  4. };
重新编译tq335x.dtb：
  1. makeARCH=armCROSS_COMPILE=arm-linux-gnueabi-tq335x.dtb
用新的tq335x.dtb启动开发板：
  1. loadmmc0:10x88000000/boot/tq335x.dtb
  2. loadmmc0:10x82000000/boot/zImage
  3. bootz0x82000000-0x88000000
最后，再次使用指令：
  1. udhcpc
进行测试，会发现开发板能够正常获取IP和DNS。如果您的路由器已经连接到了外网，还可以使用ping指令测试与外网的连接，如ping谷歌的DNS服务器：
  1. ping8.8.8.8
至此，就完成了TQ335x的Nand和网卡驱动移植，并不需要深入的了解其内部的工作原理，有问题可以留言讨论。如果想了解这两个模块的工作原理，强烈推荐韦东山老师的嵌入式教学视频，静下心来看的话，绝对物有所值。该视频还是需要一定的硬件和软件功底的，如果看不懂可以补习下C语言、基本原理图阅读等方面的知识。
