2.4.2.5 Generate Data Frame to Send (uart_frame_gui.exe)

Generate Data Frame to Send Figure 2-10 Generate Data Frame to Send

To improve efficiency and stability, a data-frame structure is used. The firmware data frame consists of a Header (0xA5 × 10), Data Length (32-bit, LSB first), Raw Data, CRC32 (JAMCRC), and an End of Packet (EOP, 0x5A × 10). The Data Length field represents the size of the Raw Data, and the CRC32 value is calculated over the Raw Data.

TI provides an executable tool that simplifies the generation of firmware data frames. By uploading a raw binary (.bin) file, the program automatically produces the corresponding firmware data frame.
