Function write_property_bytes 

fn write_property_bytes(
    property_path_str: &str,
    data: &[u8],
) -> Result<String, Error>

Write raw bytes to an arbitrary FPGA device property.

Arguments

• property_path_str: Full path under crate::config::FPGA_MANAGERS_DIR.
• data: Byte array to write.

Returns: Result<String, Error>

• Ok(String) – Confirmation of written data.
• Err(fdo::Error) if path is outside FPGA managers, or if the writing failed for any other reason

Notes:

• Path must be under crate::config::FPGA_MANAGERS_DIR - determined at compile time.

Examples

let result = control_interface
    .xlnx_sys(
        "write_property_bytes",
        "/sys/class/fpga_manager/fpga0/key",
        "BADBAD")
    .await?;
assert_eq!(result, "Byte string successfully written to /sys/class/fpga_manager/fpga0/key");
