Couldn't communicate with the adapter

[aamiel1]

After update [TYZS13] (see log) I couldn't communicate with the adapter in Zigbee...

Elelabs_EzspFwUtility.py flash -f efr32mg13p-v8-6910-57600.gbl -p COM13

I try to run: Elelabs_EzspFwUtility.py restart -m btl -p COM13
Response:

Also I try to run: Elelabs_EzspFwUtility.py restart -m nrml -p COM13
Response:
Elelabs_EzspFwUtility: Couldn't communicate with the adapter in Zigbee (EZSP) mode, Thread (Spinel) mode or bootloader mode

Any other idea?

based on the filename 57600.gbl
Your new firmware is using 57600 baudrate.
The default baudrate used by the utility is 115200.

try specifying the baudrate manually -b 57600

P.S. if that works I recommend you to find a fimrware with 115200 baudrate, as it's a more common one

Thanks,

Now if I run the command: Elelabs_EzspFwUtility.py restart -m nrml -p COM13 -b 57600
It work OK...

but if I run the command: Elelabs_EzspFwUtility.py restart -m btl -p COM13 -b 57600
I couldn't reset into bootloader mode...

and if I couldn't reset into bootloader mode I cannot flash the adapter

Any idea what the problem?

[NilsBohr]

I think your current bootloader is also 57600.
Our utility is right now hardcoded to talk to the bootloader using 115200 baudrate.

Try using 3rd party utility like TeraTerm to talk to it and send your new file using TeraTerm XMODEM send.
Or you can wait when we add 57600 baudrate for the bootloader communication, but, that won't happen any time soon.

Or you can modify the Python utility to talk to the bootloader using 57600

Hi,

I tried all the options you mentioned,
the problem seems to be that the adapter cannot be put into bootloader mode after I update it to efr32mg13p-v8-6910-57600.gbl firmware...

Maybe you have more ideas?
