Dear support,
please help mi with an issue. I got Otii Arc which is discovered under windows in device manager as: “Arc Firmware Upgrade Port”. But Otti 3.5.2 do not recognize it. I have found some topics on this forum and I was managed to flash the firmware by command:
bossac -p COM45 -i -e -w -v -b -R -U -u firmware/Arc_3.1.2.bin
Device : ATSAM3X8

Set boot flash true
But after that it dissapears from device manager and I cannot see it.
Only presing back button allows me to get to previous state “Arc Firmware Upgrade Port”
but is not usable at this point.
Could you please advice me what I can do ?
Thanks in advance
Daniel
