I design my own AT9260 board , and it can not work . The package i choiced is PQFP208. After i power it up , it can not work . I check and check the schematic again , i use almost the same setting with AT9260-EK.
To debug it , i check the oscillator of the 32.768K and main oscillator ~
i use 18.432 MHZ as main oscillator . The AT9260 will scan the external memory device . But i can not use external reset and not get "ROMINIT" from hyperterminal ~ The BMS = 1, and OSCSEL = 1, base on the spec , it should bootup from internal ROM and have the "ROMINIT" from Debug uart
