did you download the downloader before the 657__full_q2406b.dwl? I don’t know if this is required when upgrading vom 655 to 657, but in earlier versions (I still use) I always send a small file called dwl.dwl first…
Thank you jan.
I found the dwl.dwl file, I have downloaded and after that downloaded the new firmware but when I reset the modem (at+cfun=1) and try to download my application the download stops at about 55%.
I have to erase something to give space to my application?
I think it’s better to do a at+cfun=1 between downloading the dwl.dwl and the core firmware. And then to start download again with at+wdwl, so that the correct downloader is used to download the core firmware… (I agree with colin-tfe)
The firmware and OpenAT version are OK… 6.55 was for OpenAT 3.10 I believe, so you are using the right versions.
It looks like your target application is installed already (this seems a little weird since the download didn’t quite succed, so I would believe this is a bug in the core firmware… I had a similar problem with OpenAT 4.0 on another module…)
Please try if you are able to erase the application with at+wopen=4 after enabling better error reporting with at+cmee=1. If you get an error it does behave exactly as the problem I had, and I could only solve this by reflashing the module with boot pin and DWLWIN tool.
I think the problem is that they show the application to be there and than you are tempted to start it anyway (even though there was an error in the download… that’s what I think I did…) and then you can’t delete it anymore, even if stopped and also looks like it is stopped… Oh well… If you have access to DWLWIN it would be worth a try to reflash the module that way. It fixed it for me…
Unfortunately, I haven’t done anything with DOTA yet…
