Is transition from iMX6Q to iMX6D painful?

[EdSutter]

I've been working with a SABRESD board as a prep for some custom hardware that will

have similar base IO (memory, ethernet, console, etc...).  One difference is that the custom

hardware will be an iMX6D rather than a Quad-core.  For bringing up u-boot/linux I'm

assuming there's not much difference; does anyone have any real experience with this?

Hi,

on mainline, you can even run the same unmodified kernel on MX6Q and MX6D. When you use Barebox as a bootloader, it is pretty easy to abstract differences on runtime, because Barebox nowadays sets itself up from oftree.

More good news, thanks.

Not familiar with barebox.

Hello Ed,

It is not a big deal to move from a Quad Core to a Dual Core, they use the same modules. In fact, you can disable 2 cores from the Quad Core to emulate the Dual core, you just need to edit the "NUM_CORES" fuse.

That's what I was hoping.

Thanks much for responding...
