请教: 美格SLM730无法工作

[复制链接]
发表于 2022-5-3 10:57 | 显示全部楼层 |阅读模式
我按照网上查的资料,尝试适配 SLM730 LTE 模块
使用的最新的 v21.02.3 版本
编译时增加了 usb-modeswitch, kmod-mii, kmod-usb-net, kmod-usb-wdm, kmod-usb-net-qmi-wwan, uqmi, kmod-usb-serial-option, kmod-usb-serial, kmod-usb-serial-wwan, luci, luci-proto-qmi
并且修改了以下的文件:
net/usb/qmi_wwan.c
usb/serial/option.c
usb/serial/usb_wwan.c

可是一直无法成功拨号,仅仅TX有数据发出,RX一直是0

设备应该是成功识别到了

附上了修改后的驱动代码,请查阅

研究了两周时间,实在没有眉目,请大家指点一下。

谢谢了!
