NUCLEO-WB15CC Zephyr BLE support

[Filip Tefr]

Hello,

I am playing with NUCLEO-WB15CC board + zephyr + BLE beacon example. After compiling and flashing the example to the board I got "Precise data bus error" during Bluetooth initialization.

Because zephyr does not support stm32wb15 out of the box, I added board and dts definitions.

Zephyr version: zephyr-v3.3.0-877-g7deecb4e4e1d

Copro Wireless Binaries: stm32wb1x_BLE_HCILayer_fw.bin, v1.16.0

0x08009416 - points to file zephyr/include/zephyr/sys/dlist.h:499, function sys_dlist_remove

I tried to playing around with thread stack size but without any success.

I was able to compile and run basic examples (LED, Button).

Hello,

In your nucleo_wb15cc.dts file, did you adapt the different partitions according to the Flash size of the wb15 (320KB)? (See attached image)

Also, did you verified that your app can fit on the flash? On the 320KB, 80KB are needed for the BLE controller and at least 8KB for the storage_partition.

For simple BLE applications such as a beacon or a peripheral_heart_rate it should work fine but for bigger app it has to be checked.

In case your app is too heavy, you can manage partitions in flash according to your needs. Indeed, if you don’t need a bootloader and update OTA functionality, boot, slot0, slot1 and scratch partitions are not needed and can be removed.
