Operation

NOTE: The image name is limited to 16 characters. This name is shown on the LCD display of the MSP Gang

Programmer , and Image pulldown menu in the GUI.

Figure 2-18. Image Name Configuration Screen

NOTE: Since version 1.2.1.0, the number of images has increased from 16 (512KB each) to 96

(64KB each). Total image memory has decreased from 8MB to 6MB. For compatibility

purposes with older images, the numbering scheme for the new images uses an index and

subindex format (for example, 1.0, 1.1, 1.2... 1.7, 2.0, 2.1, 2.2... 12.7). The first index selects

the 512KB image memory block, and the subindex selects which 64KB portion of the 512KB

block is used. Old images that occupy 512KB always have the subindex as 0 (for example,

old Image 1 is now Image 1.0). Newly created images can occupy one 64KB block or more

(for example, a 128KB image stored in image number 2.1, will be saved to occupy blocks 2.1

and 2.2). Images 13 to 16 will be removed in future versions; however, during the transition

period, they can only be read or erased (that is, they are marked as read-only in the GUI).

The screen shown in Figure 2-19 allows the user configure what type of security is used to protect the

image file. Three options are available; however, for all three options the contents of the code file are

always encrypted and cannot be read.

Operation

NOTE: During project creation, the user can select to protect project information using various methods.

Figure 2-19. Image File Security Options

1. Any PC – Configuration can be opened on any computer using MSP Gang Programmer software. It

can be used for programming only.

2. Any PC – Password protected – Configuration can be opened on any computer using the MSP Gang

Programmer software, but only after the desired password has been entered.

3. Selected PC – Hardware Fingerprint number – Image can be opened only on the dedicated

computer with the same hardware fingerprint number as the number entered in the edited line above.

Figure 2-20 shows a window with the hardware fingerprint number. An example usage scenario would

involve calling an intended user to provide the hardware fingerprint number of their computer and

entering it within this configuration window. This restricts opening this image to only the dedicated

computer running MSP Gang Programmer software.

NOTE: The fingerprint can be used to secure the project where, for example, only a computer with a matching

hardware fingerprint can be used to view and edit the project.

Operation

The image file can be copied to internal MSP Gang Programmer memory and used for programming

target devices. Select the desired image number in the GUI and press the Load Image from File button

(see Figure 2-1). This selected image is subsequently be used for programming target devices.

2.1.10 Programming From Image File

An image file can be used to program target devices from a self-contained read-only file that has all the

necessary configuration options and code files already included. By selecting the "From Image File" Mode

you can use an image file created using the steps described in Section 2.1.9. If the image is password

protected you are prompted to enter the password before you can use the image. Alternatively, if the

image is restricted to be used on a specific PC you are unable to use the image unless your PC matches

the hardware fingerprint (for instructions on how to use images from MSP Gang Programmer internal

memory see Section 2.1.2).
