How to Implement Real-Time Logging for Pressure Data and Resolve SD Card Write Errors?

Hey guys, how can I implement a real-time logging system for pressure data using an ATmega2560, MCP2515 CAN controller, BMP280 sensor, and an SD card with Zephyr OS, and resolve the SD card file write error?
I have successfully mounted the SD card and opened the file, but yet I encountered the error "Failed to write data." If the implementation is successful, the output should log a message indicating that the data has been successfully logged to the SD card.
Here is my code in the attached file:
