is there any solution for the usb boot issue of the AMD SB800
with SeaBIOS 1.6.3 and actual Coreboot version?
I'm unfamiliar with the issue. Can you post the SeaBIOS debug output along with a description of the issue you are seeing?
I got the similar problem with seabios commit 8a161c9f5 I'm using a EHCI CDROM drive, I have a simple test on sb700 and sb800 platform. After boot to Linux OS, the Ehci CDROM drive can works fine. I suspect whether the seabios ehci driver is full support EHCI device?
Following text is the seabios log with log level 3. Thanks

There were several EHCI bug fixes committed to seabios git a few weeks back. There is a good chance these bugfixes may resolve your issue. Can you retest?
