Writing a data from ADC of F28335 controller into flash

Habib Ali Subhan

Dear All,

I am working on F28335 controller and using C2000 simulator. I am running it from flash. What I want to do is to write the data in to flash memory of my controller while making sure that no part of the code which is already present in the flash do not get interfered or replaced by the data. Please help!!

Regards

Habib Ali,

Due to the sectored nature of the flash, this is one of the F28335s weakest facets (Hint to devs: put real EEPROM in!). However, TI have written a walkaround of sorts for using the flash as an EEPROM (which is effectively what you are doing). Therefore I suggest you read the following link:

Hopefully that answers your question,

Tim

Thanks Mr. King for your kind reply

EEPROM will not be quite cost effective in our project. Can you tell me how to write the data into flash in runtime in a particular sector from adc and save my code in other sections
