Ignore the error messages. The 'nvflash' program expects some additional operations which
are never executed. Now U-Boot is starting and you should see the bootloader serial output
on your terminal program.

S
If you want to flash a new final bootloader version or to repair a damaged bootloader use
the script file from the directory 'SPI'. An important prerequisite is an existing image file as
output from the 'ImageCreator' tool (default name: spi-flasher.img) or from a Kontron BSP.
Copy your image file, the file from the directory 'SPI' and all files from the NVFLASH root
directory into the same directory.
