[U-Boot] Linux does not boot from flash, but will from RAM

[Ricardo]

Hello Tom

   Sorry for the late late reply, but you mail was hidden in my inbox.
I have been the developer of the avnet v5fx30eval patch for u-boot. I
have that board correctly running linux 2.6.27 from the latest paulus
git patch.  In order to use the ll_temac I have used a modified
version of the xilinx driver.

   On the final design I am running this command to run linux: "bootm
0xff200000 0xff9a0000 0xff7e0000 "   Try placing your data on that
areas.

   If you need more info please ask


           Best regards


BTW: Please add me to the cc next time.
