FAQ Rev D Page

First question, are you relying the HDMI display for any feature?

Regards

No we dont use HDMI on our application

Then as long as you disable ‘hdmi’ overlay it should just boot.. Feel free to share your ‘old’ boot log with a Rev B and the new boot log with Rev D so we can help you ‘downgrade’ the Rev D..
