Hi,

   I want to connect serial flash IC AT45DB641E to flexcomm interface 9 of LPC54608 development board OM13092. I am trying to read device ID of AT45DB641E which is 0x100281F but i am getting 0x281FFFFF. I think that only two bytes is getting received properly(0x281F). I have used pin 9 as sck, pin 11 as MISO, pin 13 as MOSI and pin 15 as ssel of J9 of development board. I have attached the code and the screen shot of the connection with AT45DB641E.

Please help.

 

Thanks and best regards,

Prasanna
