Tried to compile the Bluetooth: Peripheral UART-sample, (nRF Connect SDK v1.9.1) and got an error:
FATAL ERROR: command exited with status 1: 'c:\ncs\v1.9.1\toolchain\opt\bin\cmake.EXE' --build 'c:\ncs_test\Test\test_app\build\hci_rpmsg'

The reason seems to be, that in C:\ncs\v1.9.1\zephyr\samples\bluetooth\hci_rpmsg\prj.conf the CONFIG_BT_BUF_CMD_TX_COUNT is defined twice.
CONFIG_RPMSG_SERVICE=y
CONFIG_RPMSG_SERVICE_MODE_REMOTE=y
CONFIG_HEAP_MEM_POOL_SIZE=8192
CONFIG_MAIN_STACK_SIZE=512
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=512
CONFIG_BT=y
CONFIG_BT_HCI_RAW=y
CONFIG_BT_MAX_CONN=16
CONFIG_BT_CTLR_ASSERT_HANDLER=y
CONFIG_BT_HCI_RAW_RESERVE=1
CONFIG_BT_BUF_CMD_TX_COUNT=4
# Workaround: Unable to allocate command buffer when using K_NO_WAIT since
# Host number of completed commands does not follow normal flow control.
CONFIG_BT_BUF_CMD_TX_COUNT=10
I wonder if the first definition should be commented out?
