  1. Hi folks, I'm currently deciding on the layout of the debugging connectors. I have a couple of MSP430 controller boards, which I want to debug simultaneously, more or less. IEEE 1149.1 JTAG builds on a TDI-TDO daisy-chain from board to board to achive that. TI's CCS IDE supports that (I've heard so). The IEEE 1149.7 extension to this standard builds on a star-topology, where all the signals (TCK, TMS, TDI, TDO) are connected to all devices in parallel. Furthermore, the standard introduces a 2-wire variant (TI's spy bi-wire?), which I find quite attractive for this purpose. Here is the related document: http://processors.wiki.ti.com/images/e/e1/IEEE1149.7overview.pdf Now the questions: Can I connect multiple controllers to the SBW-interface? Has anyone tried that before? Thanks in advance, Bass Mati
