Abstract
A data transmission method is provided. The data transmission method may include the following steps. A first memory of a master microcontroller (MCU) of an apparatus may store an encrypted header and firmware data associated with a slave MCU of the apparatus. The encrypted header may include information corresponding to the firmware data, and the firmware data may include a plurality of firmware blocks. Then, the master MCU may transmit the encrypted header to the slave MCU. Then, the slave MCU may decrypt the encrypted header to obtain the information corresponding to the firmware data. Then, the slave MCU may obtain the firmware blocks from the master MCU according to a plurality of pre-defined settings and the information corresponding to the firmware data. Then, a second memory of the MCU may store the firmware blocks.
