Using cy8ckit-042 as programmer for external board

dandumit over 11 years ago

Dear All,

I would like to know if it's possible and some reference for using cy8ckit-042 as programmer for external board.

I have the development kit and I would like to program with it an external having psoc 4 board that I have made.

Kind Regards,

Daniel

Correct, the PSoC 4 Pioneer Kit can be used to program an external PSoC 4 only (does not support PSoC 5LP or PSoC 3 at this point..) See section A4 of the kit user guide: http://www.cypress.com/?docID…

Hi, i need same information since i will have to program few boards.
So far i didn't spend any time for research, so last option would be desoldering original chip, and connecting wires to DATA/CLK/XRES pins.
If some one know better way, i like to hear about it. Or when times comes do research myself

Well , after some research I have found a lead :
http://www.cypress.com/?app=forum&id=4749&rID=79246

section A.4 towards the end of the Pioneer Kit User Guide document - it documents what resistors you would need to short in order to use the onboard PSoC 5LP to program an external PSoC 4 (only PSoC 4 supported currently). I will keep you posted.

HAve a look on same document.CY8CKIT-042 PSoC 4 Pioneer Kit Guide
At page 94 you will see details about programmer header of PSoC5 . However using this kit I don't think that's possible to program other PSoC5 only PSoC4 kind of devices...

I have found two references for your purpose :

Using a PSoC 4 Pioneer Board as a programmer for PSoC 5LP - Cypress

It seems that Pioneer kit can program only PSoC4 ...

See section A4 of the kit user guide: http://www.cypress.com/?docID=47035

PSoC 4/external PSoC program/debug header

R32, R33, and R34

Unsolder the resistors to disconnect SWD lines from the PSoC 4.

Use J6 to connect and program an external PSoC

what would be cheapest option to program and debug PSoC5LP ?

Since for my project i used PSoC5LP, but i didn't know that psoc4 dev kit can only program PSoC4. ( Well, that would be a lesson don't take things for granted )

Your options are:
using a MiniProg3, which would be the safest solution
building a FX1-based programmer (or an FX2-based one)
roll your own solution with a MCU, based on Cypress documentation (this can then only do programming)
If we are talking about the PSoC5 on the Pioneer kit, this one has a bootloader for programming. You could go with the 3rd solution for programming it into your PSoC though.
