I wonder if it is better to use r8a7743-iwg20d-q7-dbcm-ca.dtb instead. This does the same as r8a7743-iwg20d-q7.dtb but also enables the add-on board that comes with most iwg20d kits.
The add-on board adds HDMI output, CAN bus and various SCIF interfaces.

It is also possible to write to the SPI from Linux, but having JTAG as backup is recommended as there is no backup SPI if the write goes wrong.

Kind regards, Chris
