Hi Siliciuro
Go to
http://www.utasker.com/ where you can find a tutorial (on the documents page) including how to program the FLASH using CodeWarrior and also the Freescale CF utility.
You can also find a link to an online M52233 and an Srec file which can be loaded to your own board demonstrating a web server with dynamic page support, FTP, TELNET, SMTP, and UARTs plus various other stuff. (It matches the tutorial so all instructions are there).
On the uTasker page you can read about the simple licensing conditions for the uTasker, which is free for non-commerial work (education, hobby, etc.) and if you want to receive full project code including a M5223X simulator just return the application form. Like that you can have your own web server application and 3 UARTs up and running at the weekend....
