Please see the following if you are interested in developing K60 projects with Tower Kit (or others). The developer's version is now available supporting the Tower kit with Ethernet, UART, TFT display, containing internal file system, TCP/IP with FTP, TELNET, Web Server, etc. - http://www.utasker.com/forum/index.php?topic=1252.0 as well as some IPv6 dual-stack support too.
The demo user's guide http://www.utasker.com/docs/KINETIS/uTaskerV1.4_Kinetis_demo.pdfhttp://www.utasker.com/forum/index.php?topic=1252.0 contains details on working with IAR, Keil, Codewarrior, Rowley Crossworks and GCC (projects included for all) and has developer's notes in the appendix which may be of special interest to developer's who are working on programming the peripherals in the device.
