Re: First priorities?

Priority #1:  Get a custom compiled kernel running on the board.
    *Doing this requires serial console access.
    *Serial console access requires duplicating the daughter card 
functionality
     *duplicating daughter card functionality requires dechipering the 
UART addressing, interrupts, etc

This is what I am currently working on.  I'm also working on mapping the 
flash ROM so I can make a complete image for machine recovery.  
Currently this it what I know:

Flash Base Address:  0x00400000
Flash Kernel Address:  0x0410000

Both of these can be found in 
Actiontec_DPC_Source\linux\arch\armnommu\boot\cnxt-boot-ldr\boot-ldr.S

I'm still trying to figure out where the base of the ROM disk image resides.
