Hi Joel,
I was wondering if you could share the commit hash of u-boot you tested. I would like to test it on qemu.
I recommend using master with the patch that fixes FIT hash checking:

I use a script to build the image (also attached to this email):

Run that script from the u-boot source tree. It provides an example qemu commandline when it finishes:
Hi Joel,
Thanks for providing the information. It seems that 2022.07 hace driver calculating hash by direct access + accumulative mode, and aspeedtech-bmc uboot calculating hash by scatter-gather + accumulative mode.
Currently, qemu only supports scatter-gather + accumulative mode. https://github.com/qemu/qemu/blob/master/hw/misc/aspeed_hace.c#L197-L224
