Fine for me, I only have rbtx4927.

BTW, I'm using it in 32-bit mode, as the VxWorks bootloader cannot boot
64-bit images. Are there other boards with such a limitation? Perhaps
there's even shim support for booting 64-bit kernels on such boards,
so I can test both 32-bit and 64-bit kernels?

Thanks!
