Hi
I get some misterious errors from time to time when decompressing an LZO compressed image. The output is as follows

RAM is from 0x80000000 to 0x83ffffff. The image was transfered using TFTP and has an uncompressed size of about 20MB. If I change something in the image so that the compressed data is different it works. If an image is "broken" it is always broken so the behavior is reproducable. I compress the image under windows using:
So you're saying that changing the source image results in good, or bad, behavior correct? Can you try taking a bad source image and using lzop on Linux instead?
