[meta-ti] Build core-image-minimal on tdm3730

[a.renault at kaptalia.com]

Hi there, 
I already post this message this morning on #linux-omap but I have got no 
answer, so if you please I will test here.

I am trying to build core-image-minimal (OpenEmbedded/yocto) for my TechNexion 
TDM-3730 (http://www.technexion.com/index.php/products/arm-cpu-modules/ti-
dm3730/tdm-3730) CPU : TI Sitara DM3730 at 1Ghz, DSP Core TMS320C64x at 800Mhz and 
POWERVG SGX 530

I read the CPU was omap3 compatible so I downloaded the meta-ti on 
http://layers.openembedded.org/layerindex/layer/meta-ti/ and tried to put 
"omap3evm" on the field MACHINE of local.conf.

The folder build/tmp-eglibc/deploy/images is now containing core-image-
minimal.rootfs.tar.gz, uImage, u-boot.bin and MLO  but when I tried to install 
them on my board, I have got the next issue : 

Error: unrecognized/unsupported machine ID (r1 = 0x00000c78). Available 
machine support:ID (hex)	NAME 000005ff	OMAP3 EVM Please check your kernel 
config and/or bootloader.

I understand what happen but I don't know how to fix it. 

I also tried to build with MACHINE=am37x-evm, got the same issues.
am37x seams to be close to dm37x didn't it?

Did not tried TI Sitara AM3517 EVM.

Do you have any idea of what I should try to do. Did you know someone who 
succeed to build yocto on that card? 
I saw angstrom narcissus (http://narcissus.angstrom-distribution.org/) 
proposing to build a rootfs for dm3730-am3715-evm but all the selected package 
selected failed.
