· Brought up the IMX477 camera sensor on a custom board with dual CSI interfaces.

· Added memory copy functionality to the SiMa memory library with support for multi-threaded operations.

· Added I2C communication path from ISP to sensor via the V4L2 layer.

· Made CSI data lanes configurable in the MIPI CSI pipeline to support multiple camera configurations.

· Updated FPS settings for IMX477 RAW12 formats to ensure compatibility between SOM and DVT boards.

· Verified I2C-based RTC (rv3028) hardware integration on the custom board and ensured Linux driver functionality.

· Conducted functional testing to ensure accurate timekeeping and I2C communication, reducing system clock errors across reboots.

· Developed a standalone SDMA test driver to evaluate memory transfer paths: DDR to DDR, DDR to OCM, and OCM to DDR. Added device tree nodes for SDMA0 and SDMA1.

· Measured and analyzed data throughput and latency metrics for two SDMA engines present in the custom SoC.
