I am using Mango green board and WP7502 for now, legato version 16.07.
My problem is that after I connect to legato through ssh, I can do all the “read” operations such as “cm info”, “cm data”, “cm sim” or some other commands. But if I want to unlock the SIM card through “cm sim enterpin xxxx” or connect to internet through “cm data connect &”, ssh crashes and reports the error “Connection to 192.168.2.2 port 22: Broken pipe”.
What I have tried:
- I tried to connect through linux and window systems and they get the same problem, which I guess the problem is not from my system settings.
- If I put the SIM card to my smartphone, it works fine, and I am sure SIM’s APN setting is correct in legato.
- One month ago, everything is working.
- I want to reset the legato system, but I do not know how. If I enter “fwupdate download FILE”, it said “FILE” is not found, if I enter “fwupdate query”, it said " can’t connect to service; is fwupdateService running?".
Can anyone help me with this problem?
Thank you very much!
