segmentation violation

[arwie]

I just tried to update the firmware of my nano iot 33 board. The updated failed and left my board unusable (no /dev/ttyACM0 any more). How can I restore my board?

./updater -flasher firmwares/NINA/FirmwareUpdater.mkrwifi1010.ino.bin -firmware firmwares/NINA/1.4.1/NINA_W102.bin -port /dev/ttyACM0 -programmer /home/client/.arduino15/packages/arduino/tools/bossac/1.7.0-arduino3/bossac

@facchinm do you've got any idea about what happened here?

[facchinm]

@aentinger it should have been fixed by @cmaglie patch #11 , which refactors the serial port handling.
We should recompile and release the updated binaries

Just tried with V0.1.2 and it works! Thank you!
