QN9090 persistent storage options

MikeCalm — Thu, 15 Oct 2020 19:43:17 GMT

Hi All,

I wonder what are the best options to have persistent storage for QN9090.

As there is no EEPROM, the only way is using one or a few of the FLASH sectors.

I can't find any sample code for data storage.

Or .. Should I use external EEPROM?

Thanks,

Mike

Hi MikeCalm,

About the internal flash operation, we have the SDK which contains the flash_demo, that project will help you to finish the flash program, erase, read operation.

You can download the SDK code from this link:

https://mcuxpresso.nxp.com/en

Choose board as QN9090DK6 , and download SDK_2.6.1_QN9090DK6.

You can find the flash code in folder:

SDK_2.6.1_QN9090DK6\boards\qn9090dk6\driver_examples\flash

But, as you know , the on chip flash has the endurance limit:

If your eeprom data is write frequently, I suggest you to use the external EEPROM with I2C interface.

Wish it helps you!

If you still have questions about it, please kindly let me know!

Best Regards,

Kerry
