    <TD vAlign=top width="80%">Hi, <BR>&nbsp; I'm looking for USB support on 
      BF548. I'm trying to minimize the production programming times by loading 
      minimalistic u-boot with USB host support over UART and then execute the 
      script to flash from USB stick files. Did somebody managed to implement 
      USB support for this CPU in U-Boot? If so -- please point me to the 
      instructions.<BR>Thanks.</TD></TR>

    <TD vAlign=top width="80%">Actually, I am doing that right now.<BR>The 
      status is that I ported the corresponding Linux USB Host Controller code 
      to U-Boot completely for use with USB mass storage devices in 
      U-Boot.<BR>How well it is working is a whole different matter though. So 
      far, I haven't had time to kill the numerous bugs, which it certainly has. 
      If you want I can keep you posted on the progress ... but don't expect 
      miracles ;)</TD></TR>

    <TD vAlign=top width="80%">Difficult. It's not that I don't wanna give it 
      to you, it's that I can't. It's a university project I get graded for and 
      naturally it has to be mine. I have been working on it for quite some time 
      already and haven't achieved too much yet :( Ok, I have a huge bunch of 
      code theoretically offering all the features but so far it's not working 
      and I have to start debugging from the beginning to figure out why. I am 
      expecting some progress in the next two weeks though. After that I am 
      kinda running out of time anyway and will just have to go with whatever I 
      have then and get a grade for that. After that you can have it all and try 
      making something out of it if you want. If you think you can do it in two 
      weeks though, you should probably do it yourself, because that might be 
      safer for you ...</TD></TR>

      <P>Actually yes. It's slowly advancing. Current state is that I have 
      control traffic, hot plugging, enumeration and identification working. My 
      stick is identified as supporting the BBB protocol and last time I got 
      stuck in the bulk transfers. Somehow they are not right yet.</P></TD></TR>
