I 'm using MCIMX6D7CVT08AD chip.
As You know 'MCIMX6D7CVT08AD' is an i.MX6 dual core chip.
And EVB for i.MX6 dual core is not exist.
So we are testing Quad core EVB (MCIMX6Q).
I refer to 'i.MX_Yocto_Project_User's_Guide.pdf' doc and I using below build option.
#MACHINE=imx6qsabresd source fsl-setup-release.sh -b imx6q-qt5 -e fb
#bitbake fsl-image-qt5
As You know ima6qxx is for quad core build option.
I need to Dual core build option.
Please let me know how to build MCIMX6Q EVB for dual core.

Hello,
From Fabio Estevam :
"The dts will change depending on the mx6 variant.
We can have a single U-Boot that detects the mx6 variant and load the correct dtb.
The zImage and rootfs are common for all mx6 variants.
We do this for mx6 wandboard and mx6 cubox-i boards for example.
The kernel will automatically check for the number of cores in run-time, so it will always report
the correct number of CPUs."
From "i.MX_Linux_Release_Notes.pdf" :
Supported machine configurations : imx6qsabresd, imx6qpsabresd, imx6dlsabresd.
Kernel and device tree configurations : zImage-imx6dl-sabresd.dtb, zImage-imx6dl-sabresd-ldo.dtb,
zImage-imx6dl-sabresd-hdcp.dtb, zImage-imx6dl-sabreauto-ecspi.dtb and so on
Have a great day,
Yuri
