Hi,

Not sure if my issue is relevant to the forum.

I am right now using an ST make EEPROM. It has an SPI pin-out. I am using this EEPROM for saving some vehicle related data. The data is sent by a microcontroller. Now, the concern is that, the EEPROM is not consistent in reading, writing or erasing the data. I have configured the SPI module of my Microcontroller properly. And I am also following the sequence of steps for writing command into EEPROM and getting the work done.

Inspite of doing all this carefuly, my EEPROM is still not consistent in handling the data. if somebody has already come across this problem or if u feel that I am missing on something very important, pl guide me... Thanks n Regards Amruta

Hi Amruta!

I've just written a source code to write and read some data to external serial flash from STR710 Evaluation Board.

The serial mem is M25P10, I think.

Can you explain better the problem that you're facing? By the way, have you already seen if your SCLK memory pin are working (having burst)?

Hi,

I am using STR910 board with M25P64 serial Flash connecected through SPI0.

I am able to read Flash identification but not able to read or write.

I think i am able to earse.

Please check my source code and let me know correction.
