Re: [microblaze-uclinux] [microblaze-uclinux] U-boot can’t download “image.ub”

["Dr. Johann Pfefferl" <j.pfefferl@xxxxxxxxx>]

Hello,

I have found out that it depends also on the tftp server I use.
If I install the normal "tftpd" from the debian archive I had the same
problems. Now I use the "atftpd" package (advanced TFTP server) and
there are no longer any difficulties. u-boot sends some "timeout" and
"blksize" information to the tftp server. The normal tftpd ignores this
but the atftpd server honors this (especially the timeout stuff).

Hope this helps,
  Hans
