U-Boot and sopc-create-config-files

I am trying to U-Boot to run on the cyclone iv gx fpga development kit running on the board_update_portal example system.

I followed the instructions from the Altera wiki DasUBoot page and used sopc-create-config-files to generate the U-Boot config file from the c4gx150_fpga_bup_sopc.sopcinfo file.

I encountered many serious problems.

1) The root node of the sopcinfo file is EnsembleReport not system

2) The cpu module is altera_nios2_qsys not altera_nios2

3) The value for baseAddress is in a sub-node not an attribute

Is the sopc-create-config-files script still the recommended way to generate U-Boot configuration files?

Is there another more up to date description of how to get U-Boot working with an *.sopcinfo file created by QSYS?

Thanks for any help

    I have resolved the problem with the sopc-create-config-files script.

    The board_update_portal example for the Cyclone IV GX FPGA Development Kit uses QSYS instead of SopcBuilder so the example directory has a file c4gx150_fpga_bup_sopc.qsys but no *.sopc file.

    I was trying to use the c4gx150_fpga_bup_sopc.sopcinfo file but this does not work correctly with the sopc-create-config-files script.

    Is there an easy way to create a *.sopc file from a *.qsys file?

    Is it possible to update the sopc-create-config-files script to also use *.qsys files?
