I see the redboot banner but after the checksum error nothing This is PROBABLY not the problem you're experiencing, but I have had trouble with my EDB7212s (I have two) wherein the NOR flash [i.e. the bootable flash memory] will spontaneously go bad. We have one that travels in the field inside a working demo, and every couple of weeks it comes back here with corrupt flash. So my first thought when getting a checksum error would be just to re-flash it. >Also I'd like to build my own redboot images.

I used the command-line tools, running under Linux, and had no problem with this. However note that I did find something odd with the edb7xxx templates: if you use the "net" template instead of using the default template and adding ethernet support, the result was unbootable as a ROM application. So I think you may have been bitten by a similar problem. Jonathan (I think) posted a specific list of commands for building redboot recently, that is the specific set of commands I used. === Lewin A.R.W.
