Yocto image with uboot not working!

I have built a rpi-basic-image provided by the meta-raspberrypi layer for raspberrypi and and revolution pi. But now for my implementation I need to use uboot. With meta-raspberrypi this is also quite simple, just add RPI_USE_U_BOOT = "1"
in local.conf. But with this configuration, the image is successfully boots for raspberrypi but does not boot for revolutionpi. Is it that revpi does not have support for uboot? any suggestion to make it work?

Hi amod1,

which RPi version do you use? This might be a problem, that the image you created with Yocto is for a different Pi version as the CM (compute module) inside the RevPi.

Best regards,
Philipp

I am using Revpi Connect+, for this i have set: MACHINE = "raspberrypi-cm3". Also, again I would like to let you know without uboot, image successfully boots.

I am bit late to reply, but I happened to make this work. The problem was with version of uboot 2019.07 which seems to be a common issue for raspberrypi compute modules. I used the older version of uboot 2018.11 and everything worked fine.
