Hi Andy!
Flash Region 1 (BIOS): 0040 - 00ff
Flash Region 8 (EC): 07fff000 - 0fff (unused)
Looking at the contents of flash.bin then the EC firmware is located at
offset 0x40 which would appear to put it at the start of the IFD
BIOS partition.
Yep, the EC firmware is at
Hi Felix...
Does the EC firmware of your system reside in the IFD EC partition or in the
IFD BIOS partition? The former doesn't seem to be the case, since ifdtool
complains about nor IFD EC region being present in the IFD. For the latter have
a look at 51nb/x210 and mb/amd/mandolin where an F

which I am in the process of adding to the image with
CONFIG_HAVE_IFD_BIN and CONFIG_IFD_BIN_PATH. Does that save me having
to worry abo

You can enable CONFIG_HAVE_EC_BIN and define CONFIG_EC_BIN_PATH

to point to the EC binary and the build system will use ifdtool to
inject the binary at t
