Other Parts Discussed in Thread: CC1310

Hi,

I have few question about saving data into flash:

1- We using ~19k from 32k flash, we want to use ~10k to from the flash to save data, did it's a good idea?

2- If 1 is a good idea, did there is an easy way to manage data into flash the, data is packets is in size of 14 bytes.

3- Did using FatFS to save this kind of data is a good idea?

4- What the uses of the FatFS?

Thanks.

If you have spare space in the FLASH you can use it to save data. One limitation is how often you want to write to the FLASH since the number of writes is not unlimited.

You can only write a FLASH page at a time therefore you should collect enough data to write a full page before writing to flash.

We haven't looked into FatFS for this chip. For small FLASH sizes it could be overkill to use a file system.

It's some posts on the forum covering how to write to flash on CC1310. I suggest you do a search on "flash CC1310" or similar to find the posts that cover your need best.

Hi Jack,

please find attached a TI-RTOS example how to store data in flash: 0336.flashdemo_v1.0.zip

Of course you can try FatFS, but I am not aware that it supports our chips out of the box and we cannot provide direct support for that. You might need to write adapter code that calls the DriverLib functions according to the attached example.

Dear Richard,
i have a little Problem with the example.
In my application I would like to change a larger area in the Flash, unfortunately I get larger areas with FLASH_PAGE_SIZE problems with the function. They can perhaps tell me how the function can best be adapted to large areas.

Thanks and regards
Dirk
