Wireless Programming via Spy-Bi-Wire (2-wire)

Philip McCorkle

I'd like to get some experienced MSP430 users' thoughts on the level of difficulty of making a wireless programmer for the MSP430. I have extensive experience with the nRF24L01+ wireless transceiver by Nordic Semiconductor, as well as a good bit of experience with the MSP430. I have various projects using the MSP430 that are a really big hassle to reprogram, because they are either physically large or just a pain to hook up to my computer to program.

What I'd like to do is to make a virtually transparent wireless link with the 2-wire Spy-Bi-Wire. I use a launchpad to program all my MSP430 devices, so, I was thinking I could make a fairly simple pass-through device that the Launchpad could send normal 2-wire data over and while my target MSP430 would "receive" the data and be programmed.

Is this kind of project feasible? If so, any suggestions? This sure would make things sooo much easier in the long run, even if it takes a lot of time developing.

Thanks!

    Perhaps first thing you would want to do - read slau320.

    >any suggestions?

    Stick with wires :)

    Thanks, Ilmars. I've already parsed through a lot of the JTAG document, before, and I can see how complicated the interface is. However, what I'm proposing is a "pass through" system where I have two wireless nodes that reflect the states of the RST and TEST pins on the programmer and the MSP430 to be programmed.

    I'm a big fan of wires, but they are a hassle for a lot of my projects. :D

    To implement "simple pass through system" for JTAG, you basically need to send TMS and TDI bits to debug subject, then wait for TDO bit answer radio packet to arrive. I would rather use wires than annoyingly slow wireless debug adapter.
