Hello everybody, I have a problem:
I developed my whole project testing it in debug mode with the miniprog3 (not providing the supply: It is externally generated), and everyting works in this way. Now it's time to use the device without the miniprog3 connected. I changed the configuration from "Debug" to "Release" but in this way I think the microcontroller doesn't boot: the absorbed current is only 10mA instead of 40mA of the previous case and no output is present.
I read some technical documents and if I've understood correctly, the programmed device should boot after it sees the supply ramp and the supply values became stable. Is it correct?
I didn't found a particular pin connection specification for flash booting. Is it requested?
Device: CY8C5467LTI
Psoc Creator 3.0 updated.
Any idea of what's going on?
Thanks in advance,
Matt.

A PSoC needs the xres pin to do a precise reset. This pin is usually accessable and does work.
I would check the following:
Program your project in "Debug" mode using miniprog. Remove miniprog and re-power your board. When not working ==> Probably power/ground problem
When working, program in "Release" mode using miniprog. Remove miniprog and re-power your board. When not working ==> check *ALL* your global variables used in interrupt handlers for "volatile" declaration-

Thanks Bob,
it was a supply problem: cleaning the signal solved the issue.
Thank you for the support,
Regards,
Matt
