hi there,
we have built a gen7 1.5 (atmega 1284P @20 Mhz) for testing purposes.
the board seems to work ok (we have made few prints with it), but we have some problems:
1. we have to press the manual reset button each time when we try to load the marlin firmware. We connect to gen7 with a usb cable. As far as I have understood the reset is required only for usb-ttl cables. But why we need to press reset also with a usb cable ?
2. we have to press the reset button when we connect to the board with repetier. This is required only when the board is powered-up for the first time.
I have checked with the MCP2200 utility and the CTS/RTS is disabled.
any ideas are welcomed.
thank you,
mihai
