How to load application on to LPC2468 without erasing UBOOT

padma vathi

Hi,

I am using LPC2468 OEM board for my project.
The current enviroment settings are ...

Development environemt:VMWarePlayer DebianOS
Target ARM7 runs on uClinux

LPC2468 doesn't support GDB server ,so I have to use JTAG to debug my applications.

I tried with keil ,which erasing whole UBOOT from the flash ,so I have to reload whenever load the project.
1.My question is how can I avoid redownloading UBOOT..?
2.Can I use KEIL only to debug lpc2468 user applications.?
3. Lookslike it has 2468 builtin project ,what do I have to inorder to run some application(suppose char lcd application using GPIO pins) ..?
For that ,Do I have to change any pin configurations or need to load specific drivers ..?
or just move the application macros and definitions into keil header file and call the applicaiton init funtion in the keil project main fuction...?

How can I get it work.Thanks in advance ,I really appreciate your help..

Have a wonderfulday!
Padma.
