// Example I2C sequence (C pseudo-code) uint8_t fw_buf[128*1024]; FILE *fp = fopen("uis8141e_fw.bin", "rb"); fread(fw_buf, 1, sizeof(fw_buf), fp); // Enter firmware update mode i2c_write(0x42, 0x00, 0xA5); // unlock i2c_write(0x42, 0x01, 0x5A); // enter bootloader

# Dump SPI flash via I2C (if supported) python uis_dump.py --bus 1 --addr 0x42 --output backup_fw.bin Or using SPI programmer: uis8141e firmware

// Exit & restart i2c_write(0x42, 0x00, 0x00); // exit update mode After power cycling: FILE *fp = fopen("uis8141e_fw.bin"

# If using V4L2 driver (UIS8141E appears as /dev/videoX) v4l2-ctl -d /dev/video0 --get-ctrl=firmware_version // Enter firmware update mode i2c_write(0x42
