Worked on the Zephyr project repository, focusing on stabilizing SPI NAND driver read operations to prevent data corruption and unreliable device behavior in embedded systems. Addressed a critical bug by separating transmit and receive buffers, initializing the receive buffer to zero, and ensuring the MOSI line was not driven during read transactions by setting the transmit buffer to null. Limited the transmit buffer length to avoid overflow and corrected issues that could cause corrupted JEDEC ID reads. Utilized C programming and SPI communication expertise to enhance data integrity, resulting in more reliable device performance and reduced support incidents for embedded customers.
