When RomBOOT is not enabled, it complains "SAMBA/Applet.qml:232: Error: Could not initialize applet (status: undefined)":

Short the pins to make RomBOOT is loaded;

When try to program, it complains "qml/SAMBA/Applet.qml:232: Error: Could not initialize applet (status: 1)":

Plug off the shorted pins, and begin to program;

When can't change to binary mode:

$ sam-ba.exe -x scripts/sfSerialUboot.qml
Opening serial port 'COM10'
Error: Could not switch monitor on port 'COM10' to binary mode
Connection closed.

In serial software, such as SecureCRT, connect to COM10, and disconnect;
Then try again;

It is because the serial port operation in Windows or MinGw.

When this happens, try later:

$ sam-ba -p jlink -d sama5d2 -a bootconfig
