My Pololu TReX DMC01 arrived today, but ever since I first powered it up it continually flashes red (approx. one flash per second). The blue power LED is constantly lit.
I have tried finding some basic arduino sketches online for serial communication, and it seems that none of these work as well. After a good search online the only conclusion I have come to is that it has the wrong firmware in it (unlikely? Unless firmware has become corrupt), or I have found this from the documentation:
“Red LED flashes: There was a faulty input to the bootloader that has caused the bootloader to revert to waiting for the correct initial serial input sequence. Note: once the firmware upload is complete, the TReX will reboot and the red LED may flash as part of the startup sequence. This is not an indication of a firmware-update error. See the firmware-update section for further details.”
Is there any other problems that could be causing this?
