I tried building the bootstrap-image using OpenEmbedded for the i.MX31ADS target board.

The configuration is as below:

OE Build Configuration:
BB_VERSION = "1.8.12"
METADATA_BRANCH = "<unknown>"
METADATA_REVISION = "<unknown>"
TARGET_ARCH = "arm"
TARGET_OS = "linux-uclibc"
MACHINE = "mx31ads"
DISTRO = "minimal-uclibc"
DISTRO_VERSION = "2009.X-test-20090420"
TARGET_FPU = "soft"

The build went on fine for some time after which it hit back with the following VFP errors:

Any pointers on how to overcome these VFP errors is greatly appreciated.

Thanks.
