***MSP430F47197 + ARM Processor JFET loader Gang programmer

I found out that TI has a (14 pin) gang programmer for MSP430.

But also I do need a JFET gang programmer for our ST Processor and has 20 pins.

By any chance, do you guys know any gang flash loader that fits both or two separate loader?

    Pins and pin counts are just that: pins and pin counts. Important is their meaning.
    Both, ST and MSP, require a completely different handling (JTAG is just the hardware signal protocol). So I doubt you’ll find an interface that supports both.

    You may build an adapter that maps both (14 and 20 pin JTAG plugs) to your own self-defined 8-pin header, if you want (e.g. if you have both types on your PCB and only want one connector to save space).
    And the MSP supports the JTAG bypass command, even though none of the MSP tools do use it. So you can chain the ST as second device after the MSP with the same JTAG signal traces, as long as the ST-JTAG-software supports the bypass.
