LAUNCHXL-F28379D: How to use flash as non-volatile memory?

Hi Matthew,

Please take a look at the flash programming example in C2000Ware at C:\ti\c2000\C2000Ware_4_01_00_00\device_support\f2837xd\examples\dual\flash_programming.

Also, please review below resources:

1. F2837xD Flash API (V1.54) reference guide link: http://www.ti.com/lit/pdf/spnu629

Is there a simper way of storing data in non-volatile memory? Something like EEPROM on the Arduino boards?

Hi Matthew,

Do you program it at runtime?  

Can you dedicate two sectors for it?  Or only one location/one sector?

Thanks and regards,

Vamsi

Yes I would like to store the data at runtime.

And yes, I can dedicate one or two sectors.

Hi Matthew,

How many times do you think you need to update that variable ?

Thanks and regards,

Vamsi

About 5-10 times per session at most.

Hi Matthew,

I meant to ask: How many times in the life time of the product?

Thanks and regards,

Vamsi

50,000 to 100,000 times at most

Matthew,

If that is the case, then you can simply go with one sector and erase/program the values as you need.

No need to allocate 2 sectors and also allocate more RAM for EEPROM driver.

Current datasheet is showing 20K max W/E cycling - but we are going to update the datasheet to reflect 100K for the entire flash (all sectors together).

Thanks and regards,
Vamsi
