Problem in downloading NK.nb0 to DM355

ragesh tr
Prodigy 70 points

Hi,

    I have flashed ubl_DM35x_nand.bin and u-boot-1.2.0-dm355_evm.bin images to NAND flash on EVMDM355 using sfh_DM35x.exe  and

     set the U-Boot load and start address as 0x80100000.

The u-boot bootcmd  does the following  " tftp 80020000 EBOOT.nb0;tftp 80200000 NK.nb0;go 80020000" .    So this downloads EBoot.nb0 and NK.nb0..and starts EBoot..

When NK.nb0 size is less,the download happens correctly and the OS boots up..But when the image size exceeds 15MB,the download stops and u-boot gets started  again...

Since the u-boot size is just 128 KB and the NK image is downloaded at 80200000, I dont think there is any problem of overlapping..

Please help....

 

Thanks

Ragesh
