RE: Loading compressed image on 2500? posted 01/10/2006
[Chronological Index] [Thread Index] [Top] [Date Prev][Date Next] [Thread Prev][Thread Next]


You won't be able to compress this image and then load it. It will need
enough ram to uncompress the image and then run it. Unfortunately you have a
max of 16MB of ram, so the uncompressed image will take all the ram. The
image size being larger then flash seems odd, I would guess that something
is wrong with the image if it doesn't fit in the max flash.
