phear_me:
Anyone have a verified and working fix? I've had my Arduino for about 4 hours and just got hit with this (and I'm not using any !!! in my code, which was allegedly the cause of the issue). This has been going on for months now and I gotta be honest - I'm pretty frustrated that the (presumably bootloader) issue still seems to be unfixed.
I did put a string containing "!!!!!!!!" in my code. Deleted it but no luck, same timeout error. Uploaded the Blink example (think this resetted the memory or something) and uploaded my original code again and it works again.
weird? or not?
