issue with nrf52840_pca10040 and peripheral sample

[GerlichM]

Hello everyone,

i want to use the peripheral sample under samples/bluetooth/peripheral with the nrf52840_pca10040 board using Zephyr release 1.12.
The building via cmake and ninja works fine, however after the board is flashed i get the following output:

The Settings in the prj.conf file are the default Settings:

CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048

CONFIG_BT=y
CONFIG_BT_DEBUG_LOG=y
CONFIG_BT_SMP=y
CONFIG_BT_SIGNING=y
CONFIG_BT_PERIPHERAL=y
CONFIG_BT_ATT_PREPARE_COUNT=2
CONFIG_BT_PRIVACY=y
CONFIG_BT_DEVICE_NAME="Test peripheral"
CONFIG_BT_DEVICE_APPEARANCE=833

CONFIG_BT_SETTINGS=y
CONFIG_FLASH=y
CONFIG_FLASH_PAGE_LAYOUT=y
CONFIG_FLASH_MAP=y
CONFIG_FCB=y
CONFIG_SETTINGS=y
CONFIG_SETTINGS_FCB=y

When CONFIG_FCB=y or CONFIG_SETTINGS=y is commented out the error does not occur so i assume it has something to do with the persistent storage.

Does someone have the same issue or a solution?

Thank you

You might be busting some thread stack, since the settings usage increases stack usage. I've tested peripheral on the nRF51 USB dongle (nrf51_pca10028) without issues. I'll try to find time to check the nRF52840 tomorrow. Meanwhile, you could try analyzing or increasing the size of the various stacks (Bluetooth RX, system workqueue, main, etc) .

I'm unable to reproduce this with the latest master branch. Can you confirm the same?

@GerlichM please check you toolchain, also do try clean build starting with cmake
