Stm32 port ECOs #4, port Redboot (ROM Boot Mode is internal FLASH Boot)

Redboot Introduction

Redboot is designed for Embedded debugging and startup environments. It is an Ecos-based application that uses the hardware abstraction layer (HAL) of eCos as its basis. It is a basic function as bootloader, but can be used in any embedded system or any embedded real-time operating system. It can also be used for debugging during the product development cycle or for flash or network startup in published products. Features:

• STARTUP script support;
• Management and control of command line support;
• Access through a serial port or Ethernet port;
• Supported by GDB;
• Flash Image System Support;
• Supports the x/y modem;
• Supports starting a network with a configured BOOTP or static IP address;

It may be complicated and annoying to read the article. But in fact, with the help of eCos templates, porting Redboot on stm32 does not require any modification. It takes only a few steps, it can be easily transplanted. The transplanted Redboot is started from the flash inside the CPU. As shown in:
