lpc1788->linux 2.6.33在uc板上移植usbwifi总结(使用dw131)
编译:
使用arm-2010q1
编译是进入工程目录projects/usbwifi/目录里面,直接make clean, make
内核配置选项在usbwifi.kernel.LPC
busybox 配置选项在 usbwifi.busybox
initramfs需要的东西在 usbwifi.initramfs 里面
(1)usb ohci调试出现的问题为usb ohci的中断进不去,查的最后结果是因为usb stctl设置问题,设置为3就可以了。
首先下载的dw131的驱动,通过insmod加载,然后在iwconfig的时候出现挂机,pc在0x1c地址出错,后来查出是驱动问题
修改驱动代码,dw131使用的是r8721的驱动,是在device/staging device类别里面,但是2.6.33驱动里面是没有的,查到的最近的
是2.6.37,拷贝到2.6.33的驱动里面,修改kconfig,及makefile两个文件
iwconfig 来自于wireless tool编译。
驱动正常

(2)ethernet 调试问题
ethernet ping 的时候有发送指示等在闪,但是在host端没收到数据,后来查出是mdix问题,接着在0x19寄存器里面强制为
mdix_force模式就可以了,不知道为什么
(3)mtdblock的flash驱动问题
首先在u-boot里面使用发现读不出id,查到是地址问题,ea板接的是cs0, 而uc板接的是cs1,所以p4.31要写入到配置表,
配置表位于iomux.c里面,cofig.h文件的地址也是要改的0x80000000->0x90000000
这次有数据了,但还是读不出id,(读出是错的),查原理图发现shift有问题。默认scs里面的shift是设置为1的,而uc板是
需要shift的,所以要设置为0才可以.
启动发现id对了。
另外的就是jedec_flash.c里面要写入flash的信息 sst39vf6410在u-boot 2010.6里面是没有的。
在linux下面除了要改flash的base 地址要改,也要写入jedec_flash.c里面的配置信息,
flash的容量也要改成8m
