'<err> spinel_ipc_backend: IPC endpoint bind timed out' when using custom NRF53

joelh

I Have created an NRF53 custom board, but i receive error ‘<err> spinel_ipc_backend: IPC endpoint bind timed out’ when flashing it with a basic hello world sample with the following kconfig settings:

# nothing here
CONFIG_USE_SEGGER_RTT=y
CONFIG_RTT_CONSOLE=y

# Config logger
CONFIG_LOG_BACKEND_RTT=y
CONFIG_LOG_DEFAULT_LEVEL=4
CONFIG_NETWORKING=y
CONFIG_LOG=y


# nRF board library
CONFIG_DK_LIBRARY=y

# Configure sample logging setting
CONFIG_LOG=y
CONFIG_OPENTHREAD_LOG_LEVEL_NOTE=y
CONFIG_OPENTHREAD_DEBUG=y

# Generic networking options
CONFIG_NETWORKING=y

# L2 OpenThread enabling
CONFIG_NET_L2_OPENTHREAD=y

# Network shell
CONFIG_SHELL=y
CONFIG_OPENTHREAD_SHELL=y
CONFIG_SHELL_ARGC_MAX=26
CONFIG_SHELL_CMD_BUFF_SIZE=416

#Network sockets
CONFIG_NET_SOCKETS=y
CONFIG_NET_SOCKETS_POSIX_NAMES=y
CONFIG_NET_SOCKETS_POLL_MAX=4

CONFIG_ASSERT=y
CONFIG_ASSERT_NO_COND_INFO=y
CONFIG_MBEDTLS_SHA1_C=n
CONFIG_FPU=y

# # For Building with TFM
CONFIG_BUILD_WITH_TFM=y
CONFIG_OPENTHREAD_CRYPTO_PSA=y

I Have found that setting CONFIG_NET_L2_OPENTHREAD=n seems to fix the problem, but as far as i can tell, that is because there is no child image flashed to network core thus the IPC is not in use.

any help would be greatly appreciated, heres a link to the board
