自己写的一个基于kb9202开发板的bootloader，实现了一个命令行处理和xmodem文件下载功能，可以装载一般的应用程序...

SMALL RTOS是为小ram系统单片机编写的,目前仅在51系列单片机上成功运行,还没有在其它单片机上移植(目前我仅有51和avr的开发系统).在小ram系统单片机如51系列上运行tcp/ip 协议栈是不太现实的.一般tcp/ip 协议栈需要在32位单片机上运行,在8位机上运行太勉强(51是8位机),除非您只运行ip协议.建议使用ucos/ii操作系统或是嵌入式linux,并选用arm或龙珠系列单片机-SMALL RTOS for small microcontrollers ram system, written in 51 series of microcontrollers currently only on the successful operation, no other MCU on the transplant (currently I am only 51 and avr development system). In the small ram System-on- machines such as the 51 series of films running on tcp/ip protocol stack is not very realistic. General tcp/ip protocol stack need to run 32-bit microcontrollers in the 8-bit machine running Taimian Jiang (51 is the 8-bit machine), unless you run only ip protocol is suggested. ucos/ii operating system or embedded linux, and use arm or Pearl Series MCU ..
