s3c6410 arm移植實驗一:nfs 無法掛載的問題。

ARM 375瀏覽

最近在學習嵌入式系統的移植,用的飛凌的6410的開發板。
最先依照飛凌的資料完成了一遍,可以通過nfs掛載系統。

接著自己著手移植3.6.6的系統,以及busybox,但是在nfs掛載的時候出現了問題。
具體情況如下:
服務端系統是Fedora18,關閉了firewalld,啟動rpcbind和nfs-server(飛凌的2.6.28kernel可以掛載飛凌的系統文件)。

NFS-server:

問題如上,查遍了google、baidu、bing,沒遇見過類似的情況,先記下來,接著研究

另外不知道有沒有同學遇到過類似的情況而解決的,望賜教,謝謝!

這個問題今天解決了!
原因是kernel的dm9000網卡驅動未移植。
移植操作可見:http://blog.csdn.net/acanoe/article/details/7516341
在這里,也轉載一下這位同學的操作部分。

s3c6410的dm9000移植。
1. 添加頭文件支持

點擊(此處)折疊或打開

  1. #incude <linux/dm9000.h>

2. 添加宏定義和結構體:

點擊(此處)折疊或打開

  1. //add by acanoe dm9000
  2.     /* Ethernet */
  3.     #define S3C64XX_PA_DM9000 (0x18000000)

  6.       
  7.       
  8.     static struct resource dm9000_resources[] = {
  9.         [0] = {
  10.             .start = S3C64XX_PA_DM9000,
  11.             .end = S3C64XX_PA_DM9000 + 3,
  12.             .flags = IORESOURCE_MEM,
  13.         },
  14.         [1] = {
  15.             .start = S3C64XX_PA_DM9000 + 4,
  16.             .end = S3C64XX_PA_DM9000 + S3C64XX_SZ_DM9000 - 1,
  17.             .flags = IORESOURCE_MEM,
  18.         },
  19.         [2] = {

  21.             .end = IRQ_EINT(7),
  22.             .flags = IORESOURCE_IRQ | IRQF_TRIGGER_HIGH,
  23.         },
  24.     };
  25.       
  26.       
  27.     static struct dm9000_plat_data dm9000_setup = {
  28.         .flags = DM9000_PLATF_16BITONLY,
  29.         .dev_addr = { 0x08, 0x90, 0x00, 0xa0, 0x90, 0x90 },
  30.     };
  31.

  38.         .dev = {
  39.             .platform_data = &dm9000_setup,
  40.         }
  41.     };
  42.     //#ifdef CONFIG_DM9000
  43.     //add by acanoe dm9000

3. 修改smdk6410_devices結構體

點擊(此處)折疊或打開

  1. static struct platform_device *smdk6410_devices[] __initdata = {
  2. ...
  3. ...
  4. #ifdef CONFIG_DM9000
  5. &s3c_device_dm9000, // dm9000 driver add by acanoe
  6. #endif
  7. // add by acanoe 2
  8. // &smdk6410_smsc911x,// Canceled by acanoe 對于OK6410 的網卡實驗來說,這一項一定要注釋掉。
  9. ...
  10. ...
  11. };

OK,編譯成功。啟動如下:

感謝木易小舟同學。

后續使用過程的問題:
某一次,不小心弄壞了服務端的rootfs,一時手賤就把rootfs刪掉。不過幸好有個不完全版的備份。
再次解壓出rootfs之后,啟動出現如下錯誤:

點擊(此處)折疊或打開

  1. Failed to execute /linuxrc. Attempting defaults...
  2. Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.

檢查rootfs文件系統:
1,存在linuxrc,鏈接到/bin/busybox;

2,linuxrc有可執行權限。

找了很久的原因,后來發現,需要將交叉編譯器目錄下的lib文件拷貝到nfs系統中。
如:

  1. yes | cp /opt/FriendlyARM/toolschain/4.4.3/arm-none-linux-gnueabi/lib/* /zhangsh/rootfs/lib/ -avf


注意,是/opt/FriendlyARM/toolschain/4.4.3/arm-none-linux-gnueabi/lib而不是/opt/FriendlyARM/toolschain/4.4.3/lib/
