移植完毕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的维护的内核真的非常健壮，DTS真的非常强大。

1. Nand驱动移植

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，此处不做不论什么改动，详情例如以下：

  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，并放到开发板上执行。这时我们会发现内核能够识别Nand，可是由于没有开启OMAP的BCH功能会报一处错误。开启该配置项的方法例如以下：

  1. Device Drivers  --->
  2. 	<*> Memory Technology Device (MTD) support  --->
  3. 		<*>   NAND Device Support  --->
  4. 			<*>     Support hardware based BCH error correction

保存配置并退出menuconfig，然后又一次编译内核并放到开发板上执行，此时会发现内核已经能够正常识别Nand了，完整的启动Log会在文章末尾给出。从这里能够看出，TI的内核维护的真的非常不错，比曾经移植三星芯片时省事非常多。

2. 网卡驱动移植

进行网卡驱动移植的方法与进行Nand驱动移植的方法同样，逻辑上讲，先应该去确认下网卡的引脚连接并在DTS中进行对应的pinmux设置，可是，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，能够直接运行指令：

  1. udhcpc

来动态获取ip（须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，默认通常是开启的），会发现开发板可以从路由器分配到IP，可是没有分配DNS，这是由于我们仅仅做文件系统时没有进行dhcp的设置。设置方法非常easy，将busybox中的examples/udhcp/simple.script复制到根文件系统的usr/share/udhcpc/文件夹下，并改名为default.script就可以。然后又一次运行：

  1. udhcpc

会发现开发板能够正常获取到IP和DNS，可是仍有一处错误，具体例如以下：

  1. @tq335x #udhcpc
  2. udhcpc (v1.22.1) started
  3. Setting IP address 0.0.0.0 on eth0
  4. [   11.489311] net eth0: initializing cpsw version 1.12 (0)
  5. [   11.576237] net eth0: phy found : id is : 0x1cc915
  6. [   11.581418] libphy: PHY 4a101000.mdio:01 not found
  7. [   11.586480] net eth0: phy 4a101000.mdio:01 not found on slave 1
  8. Sending discover...
  9. [   13.576458] cpsw 4a100000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx
  10. Sending discover...
  11. Sending select for 192.168.0.103...
  12. Lease of 192.168.0.103 obtained, lease time 86400
  13. Setting IP address 192.168.0.103 on eth0
  14. Deleting routers
  15. route: SIOCDELRT: No such process
  16. Adding router 192.168.0.1
  17. Recreating /etc/resolv.conf
  18.  Adding DNS server 10.0.0.1

參考TI官网提供的evm开发板的dts，本文对tq335x.dts做例如以下改动：

  1. &mac {
  2.     slaves = <1>;
  3.     pinctrl-names = "default", "sleep";
  4.     pinctrl-0 = <&cpsw_default>;
  5.     pinctrl-1 = <&cpsw_sleep>;
  6.     status = "okay";
  7. };

然后删除下面节点： 

  1. &cpsw_emac1 {
  2.     phy_id = <&davinci_mdio>, <1>;
  3.     phy-mode = "rgmii-txid";
  4. };

又一次编译tq335x.dtb：

  1. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- tq335x.dtb

用新的tq335x.dtb启动开发板： 

  1. load mmc 0:1 0x88000000 /boot/tq335x.dtb
  2. load mmc 0:1 0x82000000 /boot/zImage
  3. bootz 0x82000000 - 0x88000000

最后，再次使用指令：

  1. udhcpc

进行測试，会发现开发板能够正常获取IP和DNS。假设您的路由器已经连接到了外网，还能够使用ping指令測试与外网的连接，如ping谷歌的DNSserver： 

  1. ping 8.8.8.8

至此，就完毕了TQ335x的Nand和网卡驱动移植，并不须要深入的了解其内部的工作原理，有问题能够留言讨论。假设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。该视频还是须要一定的硬件和软件功底的，假设看不懂能够补习下C语言、基本原理图阅读等方面的知识。
