Hi everybody,

   


   

I have an issue, I haven't succeeded to solve it during my working day. ( i'm french)

   

I attend a sandwich course and for my project I'm working on a Cypress CY38C3246 PVI 122 ( psoc 3).

   

I can program it without problem With a miniprog3 

   

But, because there is a "but", once my Cypress is turned off during a few seconds an issue gets happened. 

   

Though my board is supplied, I must shortcircuit Xres with Vcc to start my cypress.

   


   

In situation:

   

I have connected a LED to show me that my board works.

   

I supply my board and the light of the LED is very weak and fix. It should blink because I have coded that.

   

When I shortcircuit xres on Vcc manualy, the LED blinks, it is the evidence that the Cypress works.

   


   

Does Someone have  an idea? 

   


   

Thanks in advance.

   

Antoine G.

When the miniprog is attached to the PSoC3 a power-down and up again may lead to undesirable halts and the program not starting. Detach the miniprog3 first and with a power-up the PSoC should run.
