If I get the schematic right, I think one has just to desolder the zero ohm resistors R32, R33, and R34.

As I already have a Pioneer Kit, I would rather like to use it as my general programmer. So no restrictions otherwise on the KitProg?


Not as far as I'm aware, though I haven't tried. Cypress's SWD implementation seems fairly consistent, so I think it'll be able to program any PSoC 3, 4 or 5 device.

on the cypress support forums, a cypress employee said that PSOC5 based the programmer inside the pioneer kit only had support for PSOC4 devices but that it might change in the future. Also, it is just a matter of desoldering some resistors to be able to program external PSOC4 boards. but you will need the 50mill keyed headers.

Does anyone know a TE (tycoElectronics )part number for the 10pin 50mill JTAG headers? I bought some 50mill headers from TE but they are not keyed and don't fit the standard JTAG and miniprog3 10pin cable.

50 mill?, is that 0.05" 1.27mm headers?, same as the one for cortex debugging?

50 mil is 0.05". PSoC uses that instead of the more common 0.1" for some reason. I haven't been able to find keyed headers either - I've been using non-keyed header strips instead. If you find a source for them, please do say.

I wrote wrong above, those headers are 0.05, I have bought exactly those since it was expensive to buy from mouser etc.
both are keyed, one are smd, other are throughhole.

or from here:
http://nl.mouser.com/search/ProductDeta ... 8wnslDRg==
http://www.digikey.com/scripts/DkSearch ... -00010T1LF

These are connectors used by Netdunio Go, and the GHI Gadgeteer's, so shops having those also sells cables etc that mathes these.

ps: I'm metric.. thus the inch/mill trouble ;)

thanks neslekkim for the links,

thouse might work, although I like better the ones cypress use as they got the shield cut on the sides so it takes significantly less PCB space.
