Hi everybody !
I'm trying to build
a projet using Zephyr & LWM2M (& Leshan).
TL;DR before I start
explaining more precisely my issue :
Having issue making
a Firmware Update on a QEMU_x86 instance.
Has anyone been able
to successfully achieve a Firmware Upgrade ? How ?
—
For now, I'm
prototyping through QEMU.
I have made my small
application to test things out, creating objects and ressources ;
defining new .xml files … There's one last thing that I need to
succeed before going deeper into my project : Firmware Update. I am
unable to make a firmware update on my QEMU instance.
I am actually using
a Leshan localhost as my LWM2M server.
I’ve tried several
things :
-
Pushing using 5/0/0 :
-
File above
200ko can’t be pushed without an issue occuring (packets stop
downloading and 5/0/3 remain at the value 1 (meaning
« downloading ») afterwards.
-
The .elf
generated for samples/basic/hello_world is around 400ko which
causes an issue here.
-
The .bin
generated, however, weight around 100ko which is fine.
-
The file
uploads (result can be seen on my terminal).
-
The 5/0/3
State value goes to 2 (« downloaded »).
-
When I
execute 5/0/2 (Update) : 5/0/5 (Update Result) goes to 1 (meaning
Firmware updated successfully).
-
However,
nothing happens, and my QEMU continue to respond to requests, no
flash occurs.
-
Pulling using
5/0/1 :
-
I've run a
local server in order to make a firmware update through 5/0/1 by
giving the http address of .bin and .elf.
-
When I try
to Update (for .elf or .bin, i have the following Update Result : 9
(meaning « Unsupported protocol » )
The problem might be
related to the fact that some functions are not yet implemented in
Zephyr (e.g : Device reboot on 3/0/4 leads to a callback
doing « /*
Change the battery voltage for testing */ » and
no reboot, same for Factory Default ) …
My
problem is pretty much described, if needed, I can send some logs.
Thank
you for your help !
Best
regards,
Thomas
