Part Number: MSP430G2210
Other Parts Discussed in Thread: MSP-GANG

Hi Team,

I have a plan to use MSP-GANG for mass production,

but before decision I should figure out a way to program 8 identical MSP430 devices with different HEX Files.

for example,

I have eight HEX files with same size but different code.

device #0: file00.hex (size N bytes)

device #1: file01.hex (size N bytes)

...

device #7: file07.hex (size N bytes)

Is it possible to program each device simultaneously with it's own HEX files ?

Thanks in advance.

Best Regards,

Andy Yang

Andy,

Sorry I don't believe this is possible. Can you share a little bit more about your use case? How many memory variants do you have?

Evan,

Thanks for your fast response.

I have developed a IoT security device using your MSP430 micro-controller.
The firmware HEX file has 16 bytes random KEY values in some flash memory area.
So, in mass production, every firmware file is not identical.

Is this memory variants critical to check whether my approach is possible or not?

You can flash and verify all 8 devices in parallel with common identical code, and than I guess one by one with 16 extra bytes. If this is possible, then it can be done only by using custom code with gang dll, not by GUI.

Thanks for your help!
I will check your suggestion(using gang dll).
