I can't program my psoc anymore (it doesn't enter in program mode)

It sounds like the final project you did, didn't include the bootloader component.  This can happen.  to recover you are going to need either a MiniProg3 or a Kitprog from another kit.  I don't know part numbers, but the PSoC 5 stick like yours include a KitProg as the breakaway portion.  (Your kit has a USB to Serial interface....)

I find it very handy having a couple of the KitProgs around.  (One for office and another for home...)  The PSoC5 kits are very cheap.  Search for the CY8CKIT-059 and you will find it.  There is also the CY8CKIT-043 which has a PSoC 4M on it.  Since you are already looking at the at the 4200 series, the 4M is an upgrade.  Both of the kits I referenced have the KitProg on them as a snapaway device and cost around $10 in the USA.

Good Luck!

I don't think so.  But either way, using a KitProg to reprogram the device is the way to go.  If you later decide to create your own PCB with a PSoC on it, you will need on then anyhow.  I figured it was the best $10 I ever spent, until I tried to use an 8 pin device.  Then I needed a real MiniProg3 to program it.  (The 8 pin devices don't have a reset pin, and require a different method to program them...)

If you are near Michigan I could help you out with programming it.

Try at ARROW or DIGI-KEY, they deliver to brazil. I would suggest you to get a CY8CKIT-043 which uses a PSoC4-M chip. The kit allows for direct programming and debugging!!

Glad I could help!  I agree with Bob also, the CY8CKIT-043 will probably be the best fit for you.  I must admit I kinda take debugging for granted.  You can't do that (debug) with the serial kits like yours!

Trying to get an application working without debugging is pretty similar to swimming with only one arm :/

You don't realize what you have until it's gone.

My first introduction to PSoC was at a trade show.  The Cypress rep was giving away the PSoC 4 and PSoC5 sticks like candy.  So I got one of both.  I started using the PSoC 4 first, as I thought it was newer.  When I got stuck (because I forgot to add the bootloader component to a project) I used the KitProg from the other stick to fix it.

Now, years later, I use PSoC 4 for everything I can, while I buy the PSoC 5 sticks to make Mouse Molesters for my coworkers while I get another KitProg for me.  (Company Corporate policy mandates our PCs lock after 5 minutes of no activity...  Most of us need to check something once every 20-30 minutes....  Such a pain!  lol)

I never really got into the PSoC 5 other than for the Mouse use.  But I make a lot of custom PSoC 4 boards now.

Yeah; I got to work with the PSoC 4 BLE module for a work project; It was so much fun I'm sad I finished it... I plan to make more things with those chips in the future.

Someday I want to setup a clustering system of them just to see how feasible it is for performance, but it might just stay a dream for now

The XRES capability on SOIC8 (and DFN16) case:

Please read "AN86439":
Note: In the PSoC 4000 parts (all parts except the 24-pin QFN), pin P1[6] is temporarily configured as XRES during
power-up until the device executes the start-up code. Do not pull this pin down during power-up as this keeps the
device in reset.

Also, please read "KBA91258":
Special functionality of P1[6] as a temporary XRES pin.

So your SOIC8 does have an XRES and can be programmed with a normal KITPROG.

Best regards!
Jurgen.

Thanks for that info Jurgen!

I didn't know that.  It doesn't help me now as I already use the MiniProg3, but it is good for future reference!
