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

Vidar uploaded an example project (and the necessary changes) in his reply with the NVS functions nvs_read() and nvs_write(). SInce the project was made for NCS 2.1.1, some changes will likely be necessary for NCS 3.1.1, but the general idea of enabling NVS in the .conf and calling the functions in the main.c file should be the same.

Best regards,

Simon

Simon,

I'm pretty sure this isn't what I need since it's reading raw flash instead of a register. I'll reach out to Vidar directly.

Just confirming that I can close this case. Seems like you and Vidar sorted it out in another case of yours:  RE: program crashes on nvs sample 

Best regards,

Simon
