AM335x(TQ335x)学习笔记——Nand&&网卡驱动移植

移植完结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保护的内核太强健,移植网卡驱动跟之前移植按键驱动相同简略,Nand驱动也是如此,所以,自己将Nand和网卡放在同一篇文章中介绍。介绍之前先慨叹一下:TI的保护的内核真的很强健,DTS真的很强壮。

1. Nand驱动移植

阅览TQ335x的原理图可知,TQ335x的Nand衔接到了GPMC上,且与DTS中默许的装备符合,此处不做任何修正,概况如下:

  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,并放到开发板上运转。这时咱们会发现内核能够辨认Nand,可是由于没有敞开OMAP的BCH功用会报一处过错。敞开该装备项的办法如下:

  1. DeviceDrivers—>
  2. <*>MemoryTechnologyDevice(MTD)support—>
  3. <*>NANDDeviceSupport—>
  4. <*>SupporthardwarebasedBCHerrorcorrection

保存装备并退出menuconfig,然后从头编译内核并放到开发板上运转,此刻会发现内核现已能够正常辨认Nand了,完好的发动Log会在文章结尾给出。从这儿能够看出,TI的内核保护的真的很不错,比曾经移植三星芯片时省劲许多。

2. 网卡驱动移植

进行网卡驱动移植的办法与进行Nand驱动移植的办法相同,逻辑上讲,先应该去承认下网卡的引脚衔接并在DTS中进行相应的pinmux设置,可是,移植完Nand后检查内核的发动Log可知,网卡现已正常辨认了,因而,能够直接履行指令:

  1. udhcpc

来动态获取ip(需求将开发板经过网线衔接到路由器并敞开路由器的DHCP功用,默许一般是敞开的),会发现开发板能够从路由器分配到IP,可是没有分配DNS,这是由于咱们只做文件体系时没有进行dhcp的设置。设置办法很简略,将busybox中的examples/udhcp/simple.script拷贝到根文件体系的usr/share/udhcpc/目录下,并改名为default.script即可。然后从头履行:

  1. udhcpc

会发现开发板能够正常获取到IP和DNS,可是仍有一处过错,具体如下:

  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
  8. Sendingdiscover…
  9. [13.576458]cpsw4a100000.etherneteth0:LinkisUp-100Mbps/Full-flowcontrolrx/tx
  10. Sendingdiscover…
  11. Sendingselectfor192.168.0.103…
  12. Leaseof192.168.0.103obtained,leasetime86400
  13. SettingIPaddress192.168.0.103oneth0
  14. Deletingrouters
  15. route:SIOCDELRT:Nosuchprocess
  16. Addingrouter192.168.0.1
  17. Recreating/etc/resolv.conf
  18. AddingDNSserver10.0.0.1

参阅TI官网供给的evm开发板的dts,本文对tq335x.dts做如下修正:

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

然后删去以下节点:

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

从头编译tq335x.dtb:

  1. makeARCH=armCROSS_COMPILE=arm-linux-gnueabi-tq335x.dtb

用新的tq335x.dtb发动开发板:

  1. loadmmc0:10×88000000/boot/tq335x.dtb
  2. loadmmc0:10×82000000/boot/zImage
  3. bootz0x82000000-0x88000000

最终,再次运用指令:

  1. udhcpc

进行测验,会发现开发板能够正常获取IP和DNS。假如您的路由器现已衔接到了外网,还能够运用ping指令测验与外网的衔接,如ping谷歌的DNS服务器:

  1. ping8.8.8.8

至此,就完结了TQ335x的Nand和网卡驱动移植,并不需求深化的了解其内部的作业原理,有问题能够留言评论。假如想了解这两个模块的作业原理,强烈推荐韦东山教师的嵌入式教育视频,静下心来看的话,肯定物有所值。该视频仍是需求必定的硬件和软件功底的,假如看不懂能够补习下C言语、根本原理图阅览等方面的常识。

3. 发动Log
