I have an nrf9160dk setup with the bluetooth-hci-lpuart flashed to the nrf52 chip and a bt peripheral sample flashed to the nrf91. This works as expected.
However, I am trying to configure the upgradable bootloader chain and as soon as I add the option
The project not longer builds with a linker error:
zephyr/drivers/bluetooth/libdrivers__bluetooth.a(h4.c.obj): in function `bt_uart_init':
C:\Users\username\ncs\v1.9.1\zephyr\drivers\bluetooth\hci\h4.c:544: undefined reference to `__device_dts_ord_82'
If I understand correctly this is because the device cannot locate the BT driver? Am I missing a configuration?
