RedBoot from DoC not working quite well

RedBoot from DoC not working quite well

[Iztok Zupet]

Hi,

 I succsessfuly replaced a DoC millenium firmware with RedBoot using the GRUB 
patch as the base. After

	>>> doc_loadbios /dev/mtd0 redboot_firmware

RedBoot boots fine (int18 or int19). But after formating my DoC with 
nftl_format utility:

	>>> nftl_format /dev/mtd0 128000

which should leave all the RedBoot blocks unchanged, my RedBoot is gone.
The whole redboot_firmware size is 126280.

Can someone tell me why the RedBoot and NFTL blocks interleave, if they do. 

Thanks
iz

You can't start a format from that address.  It's not an erase block
boundary.  (Most DoC devices have 8k erase blocks.  THat means 8192 bytes,
not 8000.)

Try erasing from 131072, rather than 128000.

 I tried but it still owerwrites or erases my RedBoot.
Size of my redboot_firmware is exactly 123.2K.

 It OK now . My RedBoot firware was 8K bytes too big, eg it loaded yust a 
little pass the 0x20000 in DoC.
