But one of them is still working on last burned hex.
Other xmega12A1u is working great. No problems.
The ones that doesnt get recognized are from same seller. Not dure if that matter.
i write in bas and upload by AS6 and avrisp MKII clonde.
2 other xmega256a3b and 128a1u are recognized fine.
Is there a way to know what suddenly happened?
EDIT i see on simple scope there is data transmited to xmega on pin 89, and pin 90 is constantly HIGH and i dont know why and is this how it should be.
