RE: [Ltib] Help regarding new board based on LPC3240, possiblity of paied work..

[Daniel Widyanto]

Hi A,

LTIB is a system builder. It gathers and combined software components to be put 
inside Linux system. To modify the driver to suit the hardware, you will need 
to modify the software itself..which is not possible using LTIB.

FYI, the DDR SDRAM and NAND timing settings are inside the S1L package. The net 
hardware init is inside the u-boot. The LED / GPIO, etc is inside the kernel. 
You need to modify the files, and recompile it to suit your board

Regards,
-daniel
