Problems with flash

[kruenheck]

I'm trying to combine two projects, C:\ncs\v3.1.1\zephyr\samples\subsys\nvs and BleFundamentalsL5E2 (Implement bonding and a Filter Accept List). They work fine independently, but in the combination, if I add CONFIG_SETTINGS=y to prj.conf (necessary for settings_load()), I get the following runtime error (every time nvs_read() is called):    <err> flash_nrf: invalid address: 0x00080ff8:8

Note that CONFIG_SETTINGS=y seems to be the main culprit, but I included the entire prj.conf below:

CONFIG_FLASH=y

CONFIG_FLASH_PAGE_LAYOUT=y

CONFIG_NVS=y

CONFIG_LOG=y

CONFIG_LOG_MODE_IMMEDIATE=y

CONFIG_NVS_LOG_LEVEL_DBG=y

CONFIG_REBOOT=y

CONFIG_MPU_ALLOW_FLASH_WRITE=y

CONFIG_UART_ASYNC_API=y

CONFIG_UART_CONSOLE=y

CONFIG_MAIN_STACK_SIZE=2048

CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048

CONFIG_NRF_FUEL_GAUGE=y

CONFIG_BT=y

CONFIG_BT_PERIPHERAL=y

CONFIG_BT_DEVICE_NAME="BCI_VM"

# Enable bonding

CONFIG_SETTINGS=y        

CONFIG_BT_SETTINGS=y

CONFIG_FLASH=y

CONFIG_FLASH_PAGE_LAYOUT=y

CONFIG_FLASH_MAP=y

CONFIG_BT_MAX_CONN=2

CONFIG_BT_SMP=y

CONFIG_BT_MAX_PAIRED=2

CONFIG_NCS_SAMPLES_DEFAULTS=y

# Enable the LBS service

CONFIG_DK_LIBRARY=y

Thank you for your attention to this matter

Hi Keith

Please check out this ticket where my colleague Vidar explains how to add NVS to your project. Let me know if you run into any further issues.

Best regards,

Simon

Hi Simonr,

I should be able to use the UICR.CUSTOMER[] register the Vidar references in that ticket. I was able to write and read from that register using nrfjprog on the command line. However, I can't figure out how to read that register in my C program. Is there an example of that, where it is clear how to specify the register address? thank you

Hi Simonr,

Have you been able to find an answer to my Question?

Thank you
