Stabilizer does not respond anymore after updating /net/broker

massirossi

Hi all,

I have a Stabilizer. I have flashed the firmware v0.10.0, then I connected it via USB to update IP and broker. I successfully changed the IP. After reboot, I changed the broker via USB with the following command:
set /net/broker "my-IP"
store /net/broker
platform reboot

Since then, I cannot connect anymore to Stabilizer (neither USB nor Ethernet). The led L1 and L3 are now red and constantly on. I tried to refresh the firmware, but the problem remains.

I cannot find information about the meaning of those LEDs--I am wondering if anybody has encountered a similar problem.

Thanks for the help!

It paniced. Connect a SWD probe to see where and why.
To clear the settings on a panicing firmware, clear the second flash bank via DFU or SWD.

Thanks, I also got help from Technosystems! The problem was that the quotation marks I was using were causing the problem--I solved it by using get, copying the quotation marks from one of the entry and using them to set the new ip.

I leave here the command to clear the settings as well (might be useful for other users):
sudo dfu-util -a 0 -s 0x08000000:mass-erase:force:leave -D dual-iir.bin

what exactly did you enter that made it panic?

I entered set /net/broker “169.254.50.245” rather than set /net/broker "169.254.50.245" (note the different quotation marks)

Unlikely. That would have been rejected outright as invalid (along the lines of Failed to set ``/broker``: Inner(1, InvalidType))
