AM1808 WinCE 6.0 Nk.bin and FAT on NAND Flash

Other Parts Discussed in Thread: AM1808, OMAPL138

Dear sir,

I have Am1808 EVM from Logic PD.I want to use it with WINCE 6.0 BSP supplied by Texas. I want to use SPI flash to store ais file and Eboot and NAND flash for 

Nk.bin and USER data partition(Eg FAT). For booting it is all right with ais-Eboot in SPI flash and i can download nk.bin from network and also mount whole  NAND  as

partition.

1) But i don't have any idea about how to make raw space in nand for nk.bin and remaining as FAT partition.

2) Can i Put some code in Eboot to store nk.bin at starting of flash and make FAT partition of remaining ?

    Rashmin,

    The code (currently commented out) for functions ReadNKFromNAND() and WriteNKToNAND() in platform\omapl138_am18x\src\boot\eboot\spiflash\flash.c is probably what you are asking for.  Take a look and it may give you a start.

    Regards,

    WM

    Thanks sir,

    i will try this on my new build.One more question,

    1) There is option in EBOOT to write downloaded NK.bin to flash, when i flash eboot to NAND and then enable Write NK.bin to flash, it download image from network and flash it to internal NAND after that OS is started but when i reboot my board and enable to boot from NAND it reads from NAND and nothing happens. I will try 2 times again but      there is nothing else. I think there is problem in image load addressing.
