Hash error when booting FIT image

How does the issue manifest

Starting from U-boot 2021.04 released in Linux4SAM 2021.04, you could notice the following error when trying to boot the FIT image:

Cause of the issue

U-boot has changed the way the configuration and image names inside the ITB file are treated.

Upstream commit 79af75f777 ("fit: Don't allow verification of images with @ nodes") has stopped the possibility of having the '@' character inside image names.


You must update your dt-overlay-at91 tree to at least linux4sam-2021.04 version.
