[ECOS] decompression error: incorrect data check

Mark-
I updated my code and tried to download my test files but ran into some
problems. Whenever I try to load a zipped file with the -d option, my
transfer locks up. The Y-modem display in minicom reports several
retries and the error "Retry 0: NAK on sector". Eventually it reports
"Retry Count Exceeded" and aborts the transfer. I tried several
different files and had success with only a very small one that was 169
bytes. All the other ones I tried, which were bigger (364B, 429B, and
623KB), locked up. I tried both X- and Y-modem with minicom and
hyperterminal and had the same results. Doing a normal load without the
-d option works fine.

A bug in RedBoot. I missed it with my test case because I wasn't looking
closely enough. Anyway, a fix is now checked in to the redboot package.
Thanks for finding and reporting that, BTW.
