          AM335x(TQ335x)學(xué)習(xí)筆記——Nand&&網(wǎng)卡驅(qū)動移植

          作者: 時間:2016-11-28 來源:網(wǎng)絡(luò) 收藏
          移植完成聲卡驅(qū)動之后本想再接再勵,移植網(wǎng)卡驅(qū)動,但沒想到的是TI維護(hù)的內(nèi)核太健壯,移植網(wǎng)卡驅(qū)動跟之前移植按鍵驅(qū)動一樣簡單,Nand驅(qū)動也是如此,于是,本人將Nand和網(wǎng)卡放在同一篇文章中介紹。介紹之前先感慨一下:TI的維護(hù)的內(nèi)核真的很健壯,DTS真的很強(qiáng)大。

          1. Nand驅(qū)動移植

          本文引用地址:http://www.ex-cimer.com/article/201611/322824.htm

          閱讀TQ335x的原理圖可知,TQ335x的Nand連接到了GPMC上,且與DTS中默認(rèn)的配置吻合,此處不做任何修改,詳情如下:

          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. };

          直接編譯內(nèi)核,并放到開發(fā)板上運行。這時我們會發(fā)現(xiàn)內(nèi)核可以識別Nand,但是因為沒有開啟OMAP的BCH功能會報一處錯誤。開啟該配置項的方法如下:

          1. DeviceDrivers--->
          2. <*>MemoryTechnologyDevice(MTD)support--->
          3. <*>NANDDeviceSupport--->
          4. <*>SupporthardwarebasedBCHerrorcorrection
          保存配置并退出menuconfig,然后重新編譯內(nèi)核并放到開發(fā)板上運行,此時會發(fā)現(xiàn)內(nèi)核已經(jīng)可以正常識別Nand了,完整的啟動Log會在文章末尾給出。從這里可以看出,TI的內(nèi)核維護(hù)的真的很不錯,比以前移植三星芯片時省事很多。

          2. 網(wǎng)卡驅(qū)動移植

          進(jìn)行網(wǎng)卡驅(qū)動移植的方法與進(jìn)行Nand驅(qū)動移植的方法相同,邏輯上講,先應(yīng)該去確認(rèn)下網(wǎng)卡的引腳連接并在DTS中進(jìn)行相應(yīng)的pinmux設(shè)置,但是,移植完Nand后查看內(nèi)核的啟動Log可知,網(wǎng)卡已經(jīng)正常識別了,因此,可以直接執(zhí)行指令:

          1. udhcpc
          來動態(tài)獲取ip(需要將開發(fā)板通過網(wǎng)線連接到路由器并開啟路由器的DHCP功能,默認(rèn)一般是開啟的),會發(fā)現(xiàn)開發(fā)板能夠從路由器分配到IP,但是沒有分配DNS,這是因為我們只做文件系統(tǒng)時沒有進(jìn)行dhcp的設(shè)置。設(shè)置方法很簡單,將busybox中的examples/udhcp/simple.script拷貝到根文件系統(tǒng)的usr/share/udhcpc/目錄下,并改名為default.script即可。然后重新執(zhí)行:
          1. udhcpc

          會發(fā)現(xiàn)開發(fā)板可以正常獲取到IP和DNS,但是仍有一處錯誤,詳細(xì)如下:

          1. @tq335x#udhcpc
          2. udhcpc(v1.22.1)started
          3. SettingIPaddress0.0.0.0oneth0

          17. Recreating/etc/resolv.conf
          18. AddingDNSserver10.0.0.1
          參考TI官網(wǎng)提供的evm開發(fā)板的dts,本文對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. };
          然后刪除以下節(jié)點:
          1. &cpsw_emac1{
          2. phy_id=<&davinci_mdio>,<1>;
          3. phy-mode="rgmii-txid";
          4. };
          重新編譯tq335x.dtb:
          1. makeARCH=armCROSS_COMPILE=arm-linux-gnueabi-tq335x.dtb
          用新的tq335x.dtb啟動開發(fā)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
          進(jìn)行測試,會發(fā)現(xiàn)開發(fā)板能夠正常獲取IP和DNS。如果您的路由器已經(jīng)連接到了外網(wǎng),還可以使用ping指令測試與外網(wǎng)的連接,如ping谷歌的DNS服務(wù)器:
          1. ping8.8.8.8
          至此,就完成了TQ335x的Nand和網(wǎng)卡驅(qū)動移植,并不需要深入的了解其內(nèi)部的工作原理,有問題可以留言討論。如果想了解這兩個模塊的工作原理,強(qiáng)烈推薦韋東山老師的嵌入式教學(xué)視頻,靜下心來看的話,絕對物有所值。該視頻還是需要一定的硬件和軟件功底的,如果看不懂可以補(bǔ)習(xí)下C語言、基本原理圖閱讀等方面的知識。
