module linuxandroid驱动集成指导

前 说 编 硬件WAKEUP管脚控 本文主要是针对广和通公司模块设备基于Android/Linux系统的驱动集成开发活动进行相关的指导说FIBOCOMMODULENCM推荐调制解调器端口(ttyACM0)，即可通AT或PPP取取MATrace端口(ttyACM1)Linux系统主要通过USB接口进行数据通信。LinuxLinux内核需要根据模块设备上报的USB设备接口加载USB驱动，USBLinuxLinux2-12-1所示，在LinuxUSB4GACM驱动：支持如modem端口，AT端口等；该驱动模块的代码（cdc-acm.c）Linux内核OPTION驱动：USBmodem端口，AT端口等；该驱动模块的代码（option.c）已经内置于Linux内核的源码。NCM驱动：USB标准的NCMPPP本节介绍PPP3.0.8/)命令（假定使用标准makemenuconfig）DeviceDriversNetworkdevicesupport本节介绍ACM{USB_INTERFACE_INFO(USB_CLASS_COMM,USB_CDC_SUBCLASS_ACM,USB_CDC_PROTO_NONE)},if(((FIBOCOM_VENDOR_ID==acm->dev->descriptor.idVendor)&&(FIBOCOM_BCDUSB!=||((FIBOCOM_IVENDOR_ID==acm->dev->descriptor.idVendor)&&(FIBOCOM_BCDUSB!=||((FIBOCOM_OVENDOR_ID==acm->dev->descriptor.idVendor)&&(FIBOCOM_BCDUSB!=acm->dev->descriptor.bcdUSB))){if(ep&&(0!=wb->urb->transfer_buffer_length)&&(0==wb->urb->transfer_buffer_length%ep-{wb->urb->transfer_flags|=}}if(usb_dev!=NULL)&&(FIBOCOM_FPRODUCT_ID==usb_dev-{printk("It'sFibocom'sH330BootID[%04x][%04x],Noneedtoloadreturn-}}针对一些休眠时USBHUBacm_reset_resume函数修改，在函数入口处直接acm_resumetty_handupttyACMAT通讯。{printk("It'sFibocommodulesreturnacm_resumedirectly\r\n");returnacm_resume(intf);}#defineFIBOCOM_VENDOR_ID0x2cb7/*Fibocomvendorid*/#defineFIBOCOM_OVENDOR_ID0x1519/*Infineonvendorid*/#defineFIBOCOM_IVENDOR_ID0x8087/*Intelvendorid*/#defineFIBOCOM_FVENDOR_ID0x058b/*Fibocom3GModuleFlashvendorid*/#defineFIBOCOM_FPRODUCT_ID0x0041/*Fibocom3GModuleFlashproductid*/#defineFIBOCOM_BCDUSB0x01105.修改文件添加函数staticinlinestructusb_host_endpoint*usb_pipe_endpoint(structusb_device*dev,unsignedintpipe){eps=usb_pipein(pipe)?dev->ep_in:dev->ep_out;returneps[usb_pipeendpoint(pipe)];}3.0.8/)命令（假定使用标准makemenuconfig）按下述指引完成ACMDeviceDrivers→USBsupportUSBannouncenewdevicesUSBModem(CDCACM)support选项：/*Fibocomproducts#define .idVendor=(vend),.bInterfaceClass=(cl),.bInterfaceSubClass=(sc),#defineFIBOCOM_VENDOR_ID0x2cb7structusb_host_endpoint*ep;{ep=usb_pipe_endpoint(this_urb->dev,this_urb->pipe);if(ep&&(0!=this_urb->transfer_buffer_length)&&(0==this_urb-printk("GHT:SendZEROPACKET####\r\n");}}3.0.8/)命令（假定使用标准makemenuconfig）按下述指引完成ACMDeviceDrivers→USBsupport→USBSerialConvertersupportUSBdriverforGSMandCDMAmodems选项：ECM本节介绍ECMTerminalkernel（“/home/ghtlinux-3.0.8ECM驱动配置DeviceDriversNetworkdevicesupportUSBNetworkAdaptersMulti-purposeUSBNetworkingFrameworkCDCEthernetsupportsmartdevicessuchascablemodems)选项：NCM本节介绍NCMLinux2.6.38Linux2.6.3238将obj-$(CONFIG_USB_NET_CDC_NCM) +=cdc_ncm.o添加至Makefile的末尾。将下述语句添加至Kconfig文件末尾。tristate"CDCNCMsupport"dependsonUSB_USBNETdefaulty将#defineFLAG_MULTI_PACKET0x2000int(*manage_power)(structusbnet*int);添加至文件中即可，添加位置可参照2.6.38的usbnet.h.intusbnet_start_xmit(structsk_buff*skb,structnet_device将obj-$(CONFIG_USB_NET_CDC_NCM) +=cdc_ncm.o添加至Makefile的末尾。将下述语句添加至Kconfig文件末尾。tristate"CDCNCMsupport"dependsonUSB_USBNETdefaulty将#defineFLAG_MULTI_PACKET0x1000int(*manage_power)(structusbnet*int);添加至文件中即可，添加位置可参照2.6.38的usbnet.h.externintusbnet_start_xmit(structsk_buff*skb,structnet_device*net);intusbnet_start_xmit(structsk_buff*skb,structnet_device将obj-$(CONFIG_USB_NET_CDC_NCM) +=cdc_ncm.o添加至Makefile的末尾。将下述语句添加至Kconfig文件末尾。tristate"CDCNCMsupport"dependsonUSB_USBNETdefaulty将#defineFLAG_MULTI_PACKET0x1000int(*manage_power)(structusbnet*int);添加至文件中即可，添加位置可参照2.6.38的usbnet.h.externintusbnet_start_xmit(structsk_buff*skb,structnet_device*net);Linux2.6.22Terminalkernel（“/home/ghtlinux-3.0.8NCM驱动配置DeviceDriversNetworkdevicesupportUSBNetworkAdapters菜单后选择Multi-purposeUSBNetworkingFrameworkCDCNCMsupport选项：ls/sys/bus/usb/drivers/cdc_acm/ls/sys/bus/usb/drivers/cdc_ether/ls/sys/bus/usb/drivers/cdc_ncm/-/dev/ttyACM*或lsaldev/ttyUSB*NCM及ECM的网络节点将生成于/sys/class/net/lssys/class/net/可查询到生成的节点。以NCM为例：Linux-3.10及以上内核，NCM网络设备节点将改变成wwan0、wwan1、wwan2唤醒时USB上会出现异常信号，导致USB设备（module）重新枚举，端口节点发生变化，导致端口唤醒后不通，应用如PPP或AT休眠唤醒不通；序如下图所示(其他模块请与我司FAE核对，以实际核对情况为准)：最后若需要远程唤醒，那么需要添加对UART_RI管脚控制，这个输出管脚是用于远程唤醒，即ls/sys/bus/usb/drivers/cdc_acm/ls/sys/bus/usb/drivers/cdc_ether/ls/sys/bus/usb/drive
