You need to apply a patch to the 2.4 Linux kernel to make it work with U-Boot for the MLxxx boards. You can find that patch as part of Xilinx Application Note 542 (XAPP542, http://direct.xilinx.com/bvdocs/appnotes/xapp542.pdf, http://direct.xilinx.com/bvdocs/appnotes/xapp542.zip)
The process on how to apply the patch is described in that application note. - Peter PS: The application note is out of date for EDK tools newer than 6.2. The patch still works, though. jeffer wrote: > Hi at all > > > Since two week I have this Problem and can't solve it. I allready read > DULG and search in > Mailinglists but I can't run linux.
