更新固件时卡在这里是什么原因，有人能帮忙解释一下吗
从内核目录里删掉

删掉后还是卡住，日志如上
就怕是usb 零包的问题了。
ubuntu pc 上的测试结果如下，也是卡在这个地方，pc上内核版本位4.15.0：

手上没有其他模块，只能在ag550q上测试
AG550Q Quectel提供的都是车载的Open固件。这个模组硬件我也拿不到。当前固件版本多少，模组的IMEI号是多少
Windows 上用QFlash 是可以升级的吧。
固件版本没法查询，现在串口没有响应
车载的Open固件包，能发我一份我试试吗
SW： AG550QCNABR03A02M8G
OC： AG550QCNAB-M28-CGASQ
SN： MPC23K20J010250
IMEI： 861089049442750
出厂应该是
问题解决了，usb接上开发板后需要重新开机，然后用你发我的固件包更新就可以了。感谢支持！
QMultiDL 是用来做多路升级使用的，并且需要Quectel License。相关申请请联系前线FAE，我无法帮你申请。
