Table 13: Device Configuration Bootheader Parameters (XML)
Important: If source and destination device modify the same parameter of
the boot header (e.g. both modify the SDRAM Parameters), Bootwizard
will refuse to patch the file.
Note: Please note that adding device entries for other flash chips to
netx.xml only affects which devices are shown in the GUI and the
generation of boot images. You will be able to generate boot images for
the newly added devices, but the flasher may not be able to access the
device. The flasher requires a much larger set of device parameters,
which are compiled into the flasher binary. It also includes its own
detection functions.
