移植MT7620A+MT7610E+MT76X2E到Openwrt trunk(Linux Kernel 3.14.32)

 

一)MT7620

1)
#if defined(CONFIG_RA_HW_NAT) || defined(CONFIG_RA_HW_NAT_MODULE)
#include "../../../linux-2.6.36/net/nat/hw_nat/ra_nat.h"
#include "../../../linux-2.6.36/net/nat/hw_nat/frame_engine.h"
#endif

#if defined(CONFIG_RA_HW_NAT) || defined(CONFIG_RA_HW_NAT_MODULE)
#include "../../../../../../net/nat/hw_nat/ra_nat.h"
#include "../../../../../../net/nat/hw_nat/frame_engine.h"
#endif

 

2)
trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620/mt7620-wifi2716_all_dpa_20130426/rt2860v2/os/linux/rt_linux.c
  将:  
    pOSFSInfo->fsuid = current_fsuid();
    pOSFSInfo->fsgid = current_fsgid();
  修改为:
    pOSFSInfo->fsuid = *(int *)¤t_fsuid();
    pOSFSInfo->fsgid = *(int *)¤t_fsgid();

3)application
编译ralink自带的gpio等程序时,可能会出现如下错误。

make[4]: Entering directory `*******/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/gpio'

staging_dir/toolchain-mipsel_24kec+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/lib  -o gpio gpio.c
gpio.c:28:28: fatal error: linux/autoconf.h: No such file or directory
 #include
                            ^

compilation terminated.
make[4]: *** [gpio] Error 1

修改a)

//#include
#include


修改b)
可能需要将源码中CONFIG_RALINK_MT7620这样的编译宏修改为CONFIG_SOC_MT7620;
因为autoconf.h只有CONFIG_SOC_MT7620宏定义;

enum {
#if defined (CONFIG_RALINK_RT3052)
 gpio2300,
 gpio3924,
 gpio5140,
#elif defined (CONFIG_RALINK_RT3883)
 gpio2300,
 gpio3924,
 gpio7140,
 gpio9572,
#elif defined (CONFIG_RALINK_RT3352)
 gpio2300,
 gpio3924,
 gpio4540,
#elif defined (CONFIG_RALINK_RT5350)
 gpio2100,
 gpio2722,
#elif defined (CONFIG_RALINK_RT6855A)
 gpio1500,
 gpio3116,
#elif defined (CONFIG_RALINK_MT7620)
 gpio2300,
 gpio3924,
 gpio7140,
 gpio72,
#elif defined (CONFIG_RALINK_MT7621)
 gpio3100,
 gpio6332,
 gpio9564,
#elif defined (CONFIG_RALINK_MT7628)
 gpio2300,
 gpio3924,
 gpio7140,
 gpio72,
#else
 gpio2300,
#endif
};

 

解决的一种方法是在gpio的Makefile文件中添加如下的定义
ifeq ($(CONFIG_SOC_MT7620),y)
EXTRA_CFLAGS += -DCONFIG_RALINK_MT7620
endif


修改c)
build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620/linux-3.14.32/drivers/char/ralink_gpio.h:37:32: fatal error: asm/rt2880/rt_mmap.h: No such file or directory

一种解决办法:
创建目录build_dir\target-mipsel_24kec+dsp_uClibc-0.9.33.2\linux-ramips_mt7620\linux-3.14.32\include\asm
将原厂SDK中的linux-2.6.36\include\asm\rt2880目录拷贝到该目录中,
#include

 


二)MT76x2e
1)
build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620/mt7612e_mt7602e_LinuxAP_3.0.2.9_iPA_20140103/rlt_wifi_ap/../rlt_wifi/os/linux/rt_linux.c:911:20: error: incompatible types when assigning to type 'int' from type 'kgid_t'
   pOSFSInfo->fsgid = current_fsgid();

 将:  
    pOSFSInfo->fsuid = current_fsuid();
    pOSFSInfo->fsgid = current_fsgid();
  修改为:
    pOSFSInfo->fsuid = *(int *)¤t_fsuid();
    pOSFSInfo->fsgid = *(int *)¤t_fsgid();

2)build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620/mt7612e_mt7602e_LinuxAP_3.0.2.9_iPA_20140103/rlt_wifi_ap/../rlt_wifi/os/linux/rt_linux.c

#if defined(CONFIG_RA_HW_NAT) || defined(CONFIG_RA_HW_NAT_MODULE)
#include "../../../linux-2.6.36/net/nat/hw_nat/ra_nat.h"
#include "../../../linux-2.6.36/net/nat/hw_nat/frame_engine.h"
#endif

#include "../../../../../../net/nat/hw_nat/ra_nat.h"
#include "../../../../../../net/nat/hw_nat/frame_engine.h"
#endif


三)MT7610e
1)build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620/mt7610e_wifi_v3006_dpa_20130613//os/linux/pci_main_dev.c:43:23: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'rt2860_remove_one'
 static VOID __devexit rt2860_remove_one(struct pci_dev *pci_dev);

解决方法可以参考以下链接:
http://www.tinylab.org/faqs/fixup-compile-error-with-devinit-devexit/
如果报错的函数前有 __devinit 或者 __devexit 等宏,那么罪魁祸首的就是这个了。因为这些宏在 Linux Kernel 3.8 之后,就已经移除了;而在3.8.1之前的版本中
在linux/init.h中有如下的定义。
* Used for HOTPLUG */
#define __devinit        __section(.devinit.text) __cold notrace
#define __devinitdata    __section(.devinit.data)
#define __devinitconst   __constsection(.devinit.rodata)
#define __devexit        __section(.devexit.text) __exitused __cold notrace
#define __devexitdata    __section(.devexit.data)
#define __devexitconst   __constsection(.devexit.rodata)

修改后参考代码如下:
