AWR1642: Information flash usecase: Save user data to QSPI flash and backup

Wesley He

Part Number: AWR1642

Hello team,

Customer plan to use a sector in QSPI FLASH to save the user information. They plan to use 2 sector, one is for backup.

The only thing that need to be concern is. If the power of device is drop when writing data to qspi-flash. Then the device should goto backup area to read the user configuration at next boot.

Do we have any reference design/code to read/write the QSPI flash like this way?

Thanks,

Wesley

Hi Wesley,

We have an app-note which describes the basic QSPI usage from the application.

On top of it, you can refer to QSPI-Flash Test application as well.

Or best way to refer SBL application which writes the MetaImage data to flash, here you can write user configuration instead of MetaImage data.

And decision to switch from one sector to other you need to write some data to sFlash which application needs to read at bootup to decide the selection of user configuration.

Hello Jitendra,

Do we have any reference code similiar to other general MCU that support to use flash as eeprom?

Thanks
