I'm trying to upload the Mozzi sinewave example to my Mega2560 in preparation for messing around with it myself. But when I tell it to upload, it doesn't work; I'll describe the errors here:
Initially begins to upload fine, with TX and RX blinking quickly and L on constantly, as normal
Then L turns off and TX and RX stop blinking quickly and begin blinking very slowly -- approximately 0.25 Hz, always both at the same time.
When I disconnect the board, a series of errors appear on the screen that likely should have appeared earlier, all from avrdude giving timeouts on stk500v2_recievemessage, with a few failed writes in between.
The code is 10848 bytes in size, and compiles perfectly.
