I downloaded the RazorsEdge Branch, by @Wetmelon, compiled it, but when I try to flash my board using odrivetool dfu I get an error when I try to confirm the flash:
“NameError: name ‘y’ is not defined”
I am running UBUNTU LTS 16.04
(I am noticing now the error code that python 2.7 is being referenced… wonder if that is the issue?)
here is full output:

I had previously flashed this board a few months ago with the endstops branch, but I was having issues getting it working so I am attempting to start anew.
alos when I try to just update the firmware with the Official Master I get different errors, even after compiling and specifiying the hex file:
thomas@localhost:~/ODrive-master/tools$ ./odrivetool dfu /home/thomas/ODrive-master/Firmware/build/ODriveFirmware.hex

odrivetool: error: too few arguments
After installing the above packages, go and download the latest release’s source code from the Python download page using the following wget command…
cd /tmp
wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tar.xz
After downloading the package, run the commands below extract the file and install…
tar -xf Python-3.7.2.tar.xz
cd Python-3.7.2
./configure --enable-optimizations
Next start the building process using the make command… Replace the #1 with the number of CPU cores on your system for faster build time… My machine has 4 CPU core, so I use the make command with -j 4 option…
make -j 4
sudo make altinstall
Do not use the standard make install as it will overwrite the default system python3 binary…
After that, Python should be installed and ready to use…
To test if Python is installed and ready to use, run the commands below
python3.7 --version
then I ran the odrivetool dfu with sudo. the board flashes but it doesn’t reconnect, but when I open ODrrivetool the board is there yay
