The script install_uboot_mtd0.sh has the following line:
VALID_UBOOT_MD5=http://jeff.doozan.com/uboot/valid-uboot.md5
to retrieve need information. However, in the shell environment of a pogo or goflex, this url is 404'd or doesn't work.
Putting the url into my desktop browser, it redirects properly. With the new url, I change the line to:
VALID_UBOOT_MD5=http://projects.doozan.com/uboot/valid-uboot.md5
and the script works.
