[0045]This invention mainly adopts STM32F103xx series single-chip microcomputer and ENC28J60 Ethernet control chip, designs a method with BootLoader function, and can remotely update firmware through network interface, and describes its design principle and realization process in detail.
[0046] Utilizing the characteristics of STM32F103xx series single-chip self-reading and writing on-chip program space, first write the BootLoader program in the on-chip Flash, and then use the BootLoader program to erase and write the user program on the single-chip microcomputer without using the traditional emulator and JTAG interface way to do programming work.
[0047] The STM32F103xx series microcontrollers are based on the ARM Cortex-M3 core and are designed for high-performance, low-cost, and low-power embedded applications. It has a clock frequency of up to 72MHz, on-chip integrated 32-512KB Flash memory, which can be used to store programs and data, 6-64KB SRAM memory, which can be ...
