Problem on flash ELR023 firmware

[Gigatrappeur]

Hello,

I try to update firmware of my Elelabs adapter.
I get this stack :

root@jeedup:/opt/elelabs/elelabs-zigbee-ezsp-utility# python3 Elelabs_EzspFwUtility.py flash -f firmware/efr32mg13p-v8-6910-57600.gbl -p /dev/ttyUSB0

This is normal ? Or just my adapter don't compatible ?

Regards,

Nope, not normal. Looks like it starts the xmodem transfer, but then drops back to the menu prompt.
Check that nothing else is using the port, stop all ha instances, etc

[Adminiuga]

Btw, are you sure you want the 57600 variant and not 115200? You would need to reconfigure zha integration.

[Gigatrappeur]

I admit that I played the sorcerer's apprentice...
What's the difference between 57600 variant and 115200 ?

In my case, I use the adapter with jeedom.

[Adminiuga]

I don't know about jeedom. The difference is the serial port baudrate settings. ELR023's default firmware uses 115200 baudrate, HUSBZB-1 uses 57600 by default. Functionally no difference, but the host software must use the same baudrate setting as the stick.

[Gigatrappeur]

Ok, I see.
thanks for your time

I will retest

[Adminiuga]

The problem you are seeing is not related to the firmware itself.
Try again. If it fails exactly same way, and it stays in bootloader menu, you could try uploading the firmware using a serial terminal with xmodem transfer. (Firmware update utility does that for you) 115200 no hardware flow control.

Hello,
sorry for the delay...

I reattemp without success. (With efr32mg13p-v8-6910-115200.gbl file)

[Adminiuga]

If you know how, then use a serial terminal and upload it manually while it is still in bootloader mode. Connect on 115200, software flow control and pressing enter you should get the boot menu.

[Gigatrappeur]

Ok, I think that's beyond my expertise.
Thank you for taking the time to answer me

FYI:

I got an ELR023 and flashed it successfully. Same bootloader:

python Elelabs_EzspFwUtility.py flash -p /dev/ttyUSB0 -f '/efr32mg13p-v8-6780-sw-115200.gbl'

@Gigatrappeur

• are you 100% sure there is nothing else on your system that might interact with the usb adapter while you try to flash it?
• have you tried flashing with the official firmware? e.g.

python Elelabs_EzspFwUtility.py ele_update -p /dev/ttyUSB0 -v zigbee

Does that also fail? If so, it might be a better place to open a bug report with Elelabs_EzspFwUtility.
