So you are flashing it by serial?
Using the swd and sck pins?
If it isn't being recognised by usb, no serial port is being configured. This leaves serial debugging.
You must be bit banging it with some gpios on something. Jlink? Openocd?
If it isn't compiling correctly, that could be because I haven't finished sorting my git out.
Short term fix to get it to compile... Take the 1 off the end of the fusee array and length
No, i am flashing via USB via I assume emulated serial. This functionality is built into the trinket m0. The device is fine, it connects and is assigned a COM port. BTW this is the way quantumcross originally did his version and has been working fine for me. I can flash this device NP with other builds, just not with the current code as-is.
When you say take the 1 off the end of the fusee array and length, do you just mean changing "sendPayload(fuseeBin1, FUSEE_BIN_SIZE1);" to "sendPayload(fuseeBin, FUSEE_BIN_SIZE);" for 1-8? If not, could you please specify which line the array and length is referenced? I searched for "array" and "length" there are no matches.
