Hi, I am using zephyr and have created a custom DTS for nrf52840 soc. I am using SIM7070G and have created a custom driver for it which is located in (zephyr/drivers/modem/simcom-sim7070g.h). The issue I am facing now is that the main file cannot seem to be getting path for SIM7070G. I have the corrected CONFIGs enabled in prj.conf, have already modified the CMakeLists.txt for modem, alongside modifications in Kconfig and Kconfig for simcom as well, also have added .yaml file in bindings as well. But for some reason it doesn't seem to be working as well either. The file cannot seem to be getting the path for it.
CMakeLists.txt present in modem folder

Driver doesn't inspect received data and all aspects of received protocol data are handled by application via work method provided. This driver differs from the pipe UART driver in that callbacks are executed in a different work queue and data is passed around in k_pipe structures. config MODEM_RECEIVER_MAX_CONTEXTS int "Maximum number of modem receiver contexts" depends on MODEM_RECEIVER range 1 10 default 1 help Maximum number of modem receiver contexts to handle. For most purposes this should stay at 1. config MODEM_CONTEXT bool "Modem context helper driver [EXPERIMENTAL]" select EXPERIMENTAL help This driver allows modem drivers to communicate with an interface using custom defined protocols. Driver doesn't inspect received data and all aspects of received protocol data are handled by application work method provided. This driver combines abstractions for: modem interface, command handler, pin config and socket handling each of which will need to be configured. if MODEM_CONTEXT config MODEM_CONTEXT_MAX_NUM int "Maximum number of modem contexts" default 1 help Maximum number of modem contexts to handle. For most purposes this should stay at 1. config MODEM_CONTEXT_VERBOSE_DEBUG bool "Verbose debug output in the modem context" help Enabling this setting will turn on VERY heavy debugging from the modem context helper. Do NOT leave on for production. config MODEM_IFACE_UART bool "UART-based modem interface" select RING_BUFFER help To configure this layer for use, create a modem_iface_uart_data object and pass it's reference to modem_iface_uart_init() along with the modem_iface reference from your modem_context object and the UART device name. if MODEM_IFACE_UART choice MODEM_IFACE_UART_BACKEND prompt "UART backend to use for modem interface" default MODEM_IFACE_UART_INTERRUPT config MODEM_IFACE_UART_INTERRUPT bool "UART-based modem interface using interrupt API" depends on SERIAL_SUPPORT_INTERRUPT select UART_INTERRUPT_DRIVEN config MODEM_IFACE_UART_ASYNC bool "UART-based modem interface using async API" depends on SERIAL_SUPPORT_ASYNC select UART_ASYNC_API endchoice if MODEM_IFACE_UART_ASYNC config MODEM_IFACE_UART_ASYNC_RX_BUFFER_SIZE int "Size in bytes of the RX buffers provided to UART driver" default 64 help Increasing this value decreases the number of UART interrupts needed to receive large packets. config MODEM_IFACE_UART_ASYNC_RX_NUM_BUFFERS int "Number of RX buffers available to the UART driver" default 2 help This value needs to be twice the number of UART modems using the driver to avoid buffer starvation. config MODEM_IFACE_UART_ASYNC_RX_TIMEOUT_US int "Timeout for flushing RX buffers after receiving no additional data" default 278 help Decreasing this value can help increase data throughput when high baudrates are used. 278us is 4 bytes at 115200 baud.

This is also limited by the length of the match_buf (match_buf_len) field as it needs to be large enough to hold a single line of data (ending with /r). endif # MODEM_CONTEXT config MODEM_SOCKET bool "Generic modem socket support layer" help This layer provides much of the groundwork for keeping track of modem "sockets" throughout their lifecycle (from the initial offload API calls through the command handler call back layers). To configure this layer for use, create a modem_socket_config object with your socket data and pass it's reference to modem_socket_init(). Note that the modem socket uses runtime allocated file descriptors reserved from the fdtable, for which the max count is set using the Kconfig option POSIX_MAX_FDS. Make sure to update this value as both the modem sockets and the POSIX_API, if used, share them. config MODEM_SOCKET_PACKET_COUNT int "Maximum number of stored packet sizes per socket" depends on MODEM_SOCKET default 6 help As the modem indicates more data is available to be received, these values are organized into "packets". This setting limits the maximum number of packet sizes the socket can keep track of. config MODEM_SHELL bool "Modem shell utilities" select SHELL help Activate shell module that provides modem utilities like sending a command to the modem UART. config MODEM_SIM_NUMBERS bool "Query the SIM for IMSI and ICCID" default y help Query the SIM card for the IMSI and ICCID identifiers.
