Mimas V1 Python broken?

I received Mimas V1 today,

where is simple example code to build and upload?
I did not find?

after installing pySerial, I did try:

$ sudo python mimasconfig.py /dev/ttyACM0 mimas.bin
[sudo] password for jay_jetson:
****************************************

if self.SendCommand(b"\x7e\x07\x01" + struct.pack('B', Char)):

please advise what to do?

I had to unplug before FPGA ran hardware,
is this expected behaviour?**

**on ubuntu:
sudo apt-get install python3-serial
sudo python3 mimasconfig.py /dev/ttyACM0 mimas.bin

Flash verification successful...

Done.
