rajeesh rarankurissi

Hi

I am using at91sam7x256 board
In our product only one parameter ID has to be set
and store in the product .So for this one parameter
using external eprom is not an ecnomical . and also
in our product we provides option for user to set ID ie not hard coded one
So How can I allot memory for setting this parameter in flash . how to identify memory location vacant place in flash . Is there any problem to use flash this purpose
my bin file size is 80KB
please helpme ...

Regards
Rajeesh

    I haven't spent the time looking through all the features of your chip. But if it supports IAP - In Application Programming - then you can use one flash sector (such as the last one) to store your parameter.

    Quite a lot of embedded devices are using a flash sector for configuration store, since it is expensive to combine EEPROM when designing processors, so quite fiew processors have an internal EEPROM.
