Hi all, 

Firstly, my intention for rasing up this topic is to first check out 
the possibility to use one JTAG tool for both MSP430 and ARM 
debugging. And actually, I want to buy the MSP430 FET isolated 
version, and I think it would work with ARM too. 

I check some ARM wiggler compatible cable, and also some MSP430 FET 
schematic from the internet. I find the electronic implemention is 
the same for both. They use XXHC244 / XXXLPT244 to buffer the JTAG 
signal line, TDO/TDI/TMS/TCK. The only different is the 14pin/20pin 
socket pin signal arrangement is different, but we can easly make an 
adaptor or even make a PCB layout change on one of the board. For 
example, we implement the MSP430 JTAG pin arrange on the socket of 
the ARM base board. 

I also attached some information that I check on the web for 
reference. I hope we can prove they are compatible. Then we can even 
buy the isolated FET from T.I. then we have a isolated version of 
wiggler also. 


have a good day
