Re: problem with gunzip()

Hi,

I have had a problem such as yours that was caused by corruption in the
compressed s-record image once it was on the target. I had thought that
Gunzip would catch this, but it did not. How is your image being
transmitted to the target? Is it over a serial link? In my case, the
S-record loader was not checking checksums and occasionally, a serial
transmission error went undetected. Gunzip did not complain, but the
uncompressed image would end up being skewed by a few bytes.
Hope this helps.

Hi

When I ported linux to a board with MPC860, 16M RAM and 2M Flash,
I met a problem.
After the program gunzip()(misc.c) the vmlinux image to address 0x0,
the contents from 0x0 to IMAGE_SIZE should be as same as that in
linux/vmlinux, right? I found that they are not same. Only from 0x0
to about 0xb500, they are same.
I don't think gunzip() has any problem.
Do you have any suggestions?
Thanks!
