Problem building RCW and ATF for LS1046A

[smiller2]

Previously,  I built the RCW and ATF for our custom board using the LS1046A.   I need to make some changes to upgrade the DDR4 DRAM.     Now neither will build for me.   The problem appears that while I have the files for our custom board,  I no longer have the source files for the remainder of the development tree.    For example, in  packages/firmware/rcw, that folder only contains our board and none of the other files or the reference design files.  

I did a "flex-builder -i repo-fetch"   thinking that would restore all the missing files.   That downloaded a bunch of stuff, but then seems to stop before getting to the RCW and ATF files.    Below are the final lines of this repo-fetch command.  It stops after a warning message about a non-existent reference.

Can someone check the repo to see if it is broken?  

Thanks.

(We build using Linux virtual machines.   I believe my build environment may have lost those files due to developer doing the Linux OS build doing a excessive clean operation.   Do to limited hard drive space, I use one build environment for both the firmware and Linux builds.)

Thank you very much.    Those steps worked and I can build again.    I also deleted the u-boot directories in both build and firmware as they are used to build the ATF.   For anyone else experiencing this,  you have to follow the steps exactly.   First build the reference design that is closest to your board.  After that builds successfully,  then copy in your modified or added files and build your board.

Please remove RCW and ATF build and source directories.

$ rm -rf build/firmware/rcw

$ rm -rf build/firmware/atf/

$ rm -rf packages/firmware/rcw/

$ rm -rf packages/firmware/atf

Then rebuild rcw and atf

$ flex-builder -c rcw -m ls1046ardb

$ flex-builder -c atf -m ls1046ardb
