AN86526 - PSoC® 4 I2C Bootloader
はじめに
Bootloaders are a common part of MCU system design. A bootloader makes it possible for a product’s firmware to be updated in the field. At the factory, initial programming of firmware into a product is typically done through the MCU's Joint Test Action Group (JTAG) or ARM® serial wire debug (SWD) interface. However, these interfaces are usually not accessible in the field.
This is where bootloading comes in. Bootloading is a process that allows you to upgrade your system firmware over a standard communication interface such as USB, I2C, UART, or SPI. A bootloader communicates with a host to get new application code or data and writes it into the device's flash memory.
