Is there anything you can do to preserve the newtmgr output in your
emails? For some reason, the entire newtmgr response gets joined into a
single line, making it difficult to read. I have reformatted the
responses below.
$ newtmgr -c mynewt_serial image list
Images:
slot=0
version: 1.0.0
bootable: true
flags: active confirmed

The empty flags field in slot 1 indicates that the device is in
loader-only mode (i.e., only slot 0 is running). It appears you have
completed step 3. With slot 1 unused, you can overwrite it with a new
app.
$ newtmgr -c mynewt_serial image test

The "test" command does not come until step 5. What about step 4,
uploading the new loader? By testing the original app image, you will
just put the device back into its original state.
$ newtmgr -c mynewt_serial reset
Done
$ newtmgr -c mynewt_serial image list ^C (cause it hang here indefinitely
so i cancel it)
It seems like your app (slot 1) doesn't support newtmgr or lacks a
newtmgr transport.
$ newtmgr -c mynewt_serial image upload splitty.img
Error: Timeout reading from serial connection
[...]
Which procedure are you following? In the split upgrade procedure (the
one I pasted in my previous email), you only upload after issuing the
"image confirm" command.
Can you please do the following:
1. Tell me something about the target you are upgrading. What loader
and app combo are you using? From the above, it appears your app may
not support newtmgr.
2. Start from step 1 in the procedure I quoted, please indicate which
step you are currently on, and don't skip any steps :).
Thanks,
Chris
