Hi Anton,

The reason the u-boot Env is = at 0x100000 address is that some costumers=C2=A0have:
one copy of= Bootblock and U-boot at 0x0 - 0x80000
second copy of Bootblock a= nd U-boot at 0x80000 - 0x100000.

we have two optio= ns;
1. Modify the OpenBMC device tree flash layout u-boot Env add= ress to 0x100000.
2. Add a patch to OpnBMC platform that usin= g openbmc flash layout to modify=C2=A0CONFIG_ENV_OFFSE= T in the u-boot.=

Thanks,

Sorry for the late reply,

<= /div>

The EVB FIU0-CS0 partitioning=C2=A0is used for testing=C2=A0the EVB and this is why it is different=C2=A0than the OpenBMC flash layout.

=C2=A0

Are you using the NPCM7XX EVB for OpenBMC? if yes we can consider to modify the flash partition to OpenBMC us= e.
