have I to do these actions?

63

are you upgrading .update file?
If so, you just need to use update command

64

yes, but it doesn’t work, so I thinked to do with swiflash, flashing the fw on the board

65

.update file is not FW, but application file.

66

I managed to swiflash the three files .cwe, .spk and .cwe in a myFirmware.spk, but I can’t flash them on the card with either of the following two methods:

67

seems you did not transfer the file to module by scp command.
So fwupdate command cannot find it.

68

I read that to do this you have to lower switch 7, reset, flash and then raise switch 7 while swiflash works. Let’s hope…

Could be there some problems?

71

As said before, use fwupdate

72

doesn’t work, I’m trying it since two weeks ago :disappointed_relieved:

73

Why does it not work?

in myFirmware there are modem.spk, legato.cwe and yocto.cwe, and I followed this procedure:

So, could be normal the fact that swice still works after two hours or is the device in loop?

76

no, I transfered the file by scp as I always done

77

You can try fwupdate an official spk and see if it works

78

i stopped this procedure…the board is in loop, i can’t enter with ssh. I noticed that yocto.cwe makes the device go in loop, every time. the only yocto that worked was for wp76, so it was wrong. i think i have problem with yocto, it is the only source of problems…

79

I’m trying also this way…

UPDATE:
It’s still working after one hour. Could be a problem of the spk file or is it normal?

probably module problem, can you switch to another module and test?
