I have this blackfin on my own board, that almost copied from 518's ezkit.
I've try to boot it any boot modes, but CPU pins are still after switching reset signal. So it doesn't want to boot.
PowerGood is tied to ground. All voltages are fine. Grounds too. Clock sourse is fine (25MHz)
Only one thing make me doubt - i've tied VCC_OTP and VPP_OTP to ground becouse I do not want to use it at all.
Is it the cause why CPU behaves like dead?
I've found only one signal, that changes after reset - CLKOUT starts to clock (37MHZ)
would glad any help. thanks
