Hi,
Iam trying to communicate between AT45DB041B and ARM9 processor usin SPI. I have configured the initial settings. iam able to WRITE/READ the buffer of AT45DB041B Serial Flash without an problem. But, iam facing problem in writing/reading the main memory page o AT45DB041B serial flash.
The COMP bit in the status register is always low indicating the result o recent main memory page to buffer compare. I checked the COMP bit by reading the status register after comparing th main memory page and buffer several times with different values, but ye the COMP bit is always low.
I dont think i have problem in reading the status register because th WRITE/READ of buffer works fine.
Iam not sure whether iam writing correctly to the main memory page or i iam reading it in a wrong way?
Iam using the command sets for all the functions given in the seria flash's datasheet.
Can anyone of you help me in fixing this problem?
Regards, Uma
