the way to use flash memory in nrf5340

[simoon]

I would like to know if there is an example of using Flash memory in a way other than QSIP

I use nrf5340 and zephyr

Hello,

way other than QSIP

I think you meant QSPI

Do you want to use SPI? 

You can check zephyr little-fs sample, and see how it could used for SDCard for example.

We are going to use the flash memory inside the nrf5340.

so we are trying to use zephyr\samples\drivers\soc_flash_nrf not little-fs sample.

Added various BT CONFIGs in the prj.conf file as y because our project uses BT solustion 

However, if CONFIG_BT=y, an error occurs that the label of Flash memory is not properly set as shown below.

(Other BT-related CONFIGs are not affected)

The following define in main.c in the soc_flash_nrf project is causing the problem.

#define TEST_PARTITION slot1_partition

#define TEST_PARTITION_OFFSET FIXED_PARTITION_OFFSET(TEST_PARTITION)
#define TEST_PARTITION_DEVICE FIXED_PARTITION_DEVICE(TEST_PARTITION)

If CONFIG_BT=y, does anything affect the Flash memory setting?

ps 

If you add CONFIG_BT=y in the prj.conf file in zephyr\samples\drivers\soc_flash_nrf  project 

you can find the same Error.

(at that time Borad selected nrf5340dk_nrf5340_cpuapp and configuration selected prj.conf for vs-code)

Hello,

When you use CONFIG_BT on NRF5340, as the soc has 2 cores, it will separately build the BT controller as a child image for the net core using hci_rpmsg.
This would invoke the partition manager which intern would ignore the flash partitions from the DTS to be ignored.
In this case you would need a static patitioning file to define flash partitions.

Please look at these tickets as well:

External Flash and MCUBoot
