Hi Stefan, >Then the vendor U-Boot port is broken.
I hope that is not the case :-( When they told me that the board has 2GB of flash, I told them that u-boot only reported 16MB. I was told not to worry about it. Vendor saves firmware for their chip (which is a PCI-e device on the board), their config files and VAR partition for their Linux image is stored in the 2GB flash. Do I need to push them to clarify as to why their u-boot is not reporting the correct flash sizes? >Otherwise you need to burn the U-Boot image into your NOR FLASH and just hope >that it works. A JTAG debugger would be handy if it doesn't work though. We have Lauterback Power Debug Interface and TRACE32 software CD. I have been told that it does support JTAG burning. Now I need to investigate it.

If your board usually boots from NOR, then it is connected to the NOR FLASH chip. The AMCC/APM evaluation boards have a jumper to toggle this chip-select between NAND and NOR. If your custom board doesn't have such a means to toggle the CS0 then you have no chance to boot from NAND. Another idea would be to build a rambooting U-Boot target for your board. This is supported for Sequoia. But not for Canyonlands. You might want to take a look at that. Otherwise you need to burn the U-Boot image into your NOR FLASH and just hope that it works. A JTAG debugger would be handy if it doesn't work though.
