Suddenly realized that I could not upload anything to my arduboy any more.
When I plug it to my desktop only the red led is lighting up (then switching off after some time). TTY device doesn’t created in the /dev folder. There is no new messages appears when I call dmesg and lsusb output doesn’t change as well.
I have tried different cables including those which worked fine earlier. Desktop software and hardware was not change since I last time use it to upload games.
Current game on arduboy: Mini Rogue from @eried repository uploaded with Arby Utility. I have used Arby Utility many times before without any problems.
Any suggestions how to fix that? Is it a software or hardware problem?
