IVT Image Table View

Allows configuration of IVT pointers.

The standard IVT Pointer contains :

• An On/Reserved togglable button (upper-left corner)

  If the pointer is set to “On”, the pointer will be saved in the IVT image in it’s specific location, and it’s corresponding image will be displayed in the Memory Layout (Memory Layout). If the pointer is set to “Reserved”, it will become grayed out and the area in the IVT Image where was saved the pointer will be filled with 0xFF

• An image file browser button (“Browse” button on the right)

  Using this button, the user can load the corresponding image, the “Size in bytes” field will be automatically updated with the size of the loaded file. Loading images is also useful for exporting the blob image (See IVT Export (IVT Export).

• A read-only field displaying the current selected file path (or “N/A” if none selected)

  This field cannot be edited manually, it will only display the current loaded file location.

• An editable start address field (the actual value of the image pointer)

  This address can be manually edited, by default it will be written in HEX format but it can also be set with a decimal format (by omitting the 0x prefix)

• A lock/unlock button for the current start address

  This button can be used to keep the pointer unchanged during the Automatic align process. To start this process press the “Align” button, in the Automatic Align section, which can be found under the IVT Image Address section

• An editable image size field

  The size field’s purpose is useful to work with when trying to arrange the IVT Pointers. It can still be manually set even with a loaded image, but the tool will automatically raise errors or warnings depending on the value set. This field’s default format is DEC but it can also receive HEX values.

There are some pointers that contain sub-images. (Application bootloader and Application bootloader (backup)). These pointers have all the fields that a regular IVT Pointer has, plus a sub-image menu, which can be toggled using the “Image” button right under the file path text field.

This sub-image has three more fields :

• RAM start pointer
• RAM entry pointer
• Code length

The fields have their own validation constraints too.

The sub-image view has also an “Export Image” button which can be used to save the current configuration. See more about this on IVT Export (IVT Export) section.
