Sanjay,

I have successfully used the flash.exe under windows 98 DOS Mode.  There
is an easier way, however, to update the Redboot image.  Simply create a
Linux Kernel that does not have the redboot partition protected ( Memory
Technology Devices (MTD)  ---> Force read-only for RedBoot system
images). Make sure that "RedBoot partition table parsing" is selected.

Once you have loaded the kernel on your board, make sure you have a
/dev/mtdblock0 device.  If you don't, you need to create one with the
"mknod /dev/mtdblock0 b 31 0" command.

Next, download the redboot.bin image to your board using tftp or ftp,
and use this command: cp redboot.bin /dev/mtdblock0.  This will replace
your redboot image with the new one.

You will note that "cat /proc/mtd" produces the following mapping:

dev:    size   erasesize  name
mtd0: 00080000 00020000 "RedBoot"
mtd1: 00100000 00020000 "zimage"
mtd2: 003c0000 00020000 "ramdisk"
           ...

Thanks.  

In regards to burning RB as I remember you need a dos machine right.  I
remember talking to Gordon about this.  The problem is we no longer
maintain any dos stuff.  Do you know if I can go into a dos window of
windows 95 or windows 98 and would flash.exe still work?  I'll try to
dig up the jtag cable tomorrow.

I notice that the redboot binary requires I know the size of the ram. 
How do I figure out what the RAM size is of the board I have?  Is there
a command in the redboot I can use?  

Thanks,
Sanjay
