Embodiment 1
[0062] According to a first aspect of the present invention, there is provided a method for data transmission of firmware system that only needs to be carried out on the transmission unit of the PC control module, comprising the following steps:
[0063] S1. Turn on the PC side, power on the embedded mainboard, and connect the embedded mainboard to the PC; open the transmission unit of the PC control module and connect it to the embedded mainboard;
[0064] S2. Turn on the PC control module, call the native tool to burn ExtBoot to the embedded motherboard;
[0065] S3. The embedded motherboard restarts, runs the ExtBoot system, and reports the Ready indicator signal;
[0066] S4. The PC control module receives the Ready indication signal, the handshake is successful, and starts to send control commands and data transmission; the transmission unit of the PC control module sets the communication parameters, loads the data, sends the start transmission command, waits for the hand...
Embodiment 2
[0101] Such as figure 1 As shown, the present invention also provides a device for burning firmware system data, including:
[0102] PC control module 1: Call the native tool to burn ExtBoot to the embedded motherboard, receive the Ready indicator signal, send control commands and data transmission, call the native tool to burn the firmware kernel to the embedded motherboard;
[0103] Embedded device main board 2: Run the ExtBoot system, report the Ready indicator signal, receive and process instructions and data, reply the response information, and complete the firmware burning;
[0104] The PC control module 1 is connected with the motherboard 2 of the embedded device.
[0105] Concrete PC control module 1 includes:
[0106] Read data unit 3: responsible for reading firmware system data into PC memory for preprocessing;
[0107] Encapsulating data unit 4; responsible for encapsulating the firmware system data into frame data according to the protocol;
[0108] Transmissi...

Abstract
The invention relates to the field of embedded device firmware burning, in particular to a firmware system data transmission method and a burning device thereof. The transmission method comprises the following steps: S1, starting the PC end, electrifying and starting up the embedded mainboard, and connecting the embedded mainboard with the PC end; s2, starting a PC control module, and calling a native tool to burn ExtBoot to the embedded mainboard; s3, restarting the embedded mainboard and running an ExtBoot system, and reporting a Ready indication signal is reported; s4, after the PC control module receives the Ready indication signal, determining that handshake succeeds, and starting control instruction sending and data transmission; s5, processing, by the embedded mainboard, the instruction and the data and replying the response information; s6, enabling the PC control module to continuously send the control instruction and transmit data until the processing is finished; s7, calling a native tool to burn the firmware kernel to the embedded mainboard, and completing firmware burning of the embedded mainboard. An operator only needs to load the required firmware system data in the transmission unit of the PC control module, and then the firmware system data can be transmitted to the embedded mainboard for burning, so that the method is simple and quick.
Description
technical field [0001] The invention relates to the field of firmware programming of embedded devices, in particular to a method for transmitting firmware system data and a programming device thereof. Background technique [0002] In the wireless electronic product solution provided by AmbiqMicro, by default, only the programming tool provided by it can be used to burn the firmware to the on-chip memory of the Ambiq series single-chip microcomputer. Due to the limitation of the on-chip storage space, the realized functions are limited and cannot be expanded. Multifunctional to meet customer needs. Contents of the invention [0003] The present invention provides a firmware system data transmission method and its burning device, aiming to solve the problem of limited storage space in the solution provided by AmbiqMicro. [0004] The present invention provides a method for transmitting firmware system data, comprising the following steps: [0005] S1. Turn on the PC, power...
