Hi Giuseppe,

When you try building by setting different mainboards, are you running make distclean between those attempts?  If not, you can easily wind up with a .config where settings and options aren't appropriate for your board.

For your Sapphire system, the AMD Bettong board might be close enough to get you started.  If you want to give it a shot, you can try the following.  Make sure you have some method for reflashing your original BIOS, of course, because this probably won't work initially.

1) Create a .config file using the following

2) Run make olddefconfig

3) I've assumed the board's two serial connectors are connected to the APU and not on a SuperIO (CONFIG_HUDSON_UART=y).  Unfortunately, the Merlin Falcon binaryPI has a "feature" that prevents this from working.  Ricardo has an easy workaround to allow the UART to function.  Cherry-pick the patch here:

Hello to all,

I'm getting confidence with coreboot for the first time. I followed instruction in the "Lesson1" article for a very basic build and everything gone well. Now I'm trying to build coreboot for a real board (amd ipc_fp4_dp not present in current release) but setting several mainbord devices results in different errors. One of these is the following:

cbfstool: /home/oxboxes/coreboot/util/cbfstool/cbfstool_image.c:666: cbfs_add_entry: Assertion '' !IS_TOP_ALIGNED_ADDRESS
(content_offset)' failed

Due to lack of tutorial to understand the coreboot structure, can someone help me to understand why the building process fail?
