rgmii ping ok in uefi shell ,but not under system
our H5 J5 pin do not acess to phy soc in hardware ,does it matter ?
Yes, that is the reason…
but H5 J5 set as gpio its level is 3.3V,phy reset and interrupt is 1.8V ,is that ok? should we need to do level conversion? on the other hand why it can ping ok in uefi but not in system .the hardware in uefi and system the same
The driver in UEFI and kernel are different…
ok , we will have a try
i really appreciate your patience, the issue has been resolved. Thanks a lot.
