Hi,
I know A0 versions of the AST2600 had an issue where eth0 was not
working, but the errata indicates this is fixed in later revisions.
I am seeing an issue on the EVB board though where eth0 (MAC1) is not
functional. The other three ports all function as expected.
On my DHCP host machine I can see DHCP requests from the AST2600, and
replies are sent. Looking at /proc/interrupts it looks very much like no
IRQs are ever generated for incoming packets.
Thanks
Graeme

Hi Gaeme,
Which soc revision and evb board revision are you using?
Can you try to use phy-mode = "rgmii-rxid" for eth0/1 in your dts?
Thanks,
Troy Lee

Hi Troy,
Soc Rev:-
U-Boot 2019.04-00083-ge5902174d9-dirty (Sep 22 2021 - 15:10:03 +0000)
SOC: AST2600-A1
EVB Rev:-
AST2600-DDR4 EVB V1.4
phy-mode = "rgmii-rxid" instead of "rgmii" improves the issue and I now
get DHCP on that interface, but packet loss is still hight compared to
eth1 (MAC2).

Hi Graeme,
We'd like to ask you to dump SCU registers (0x1e6e2000 ~ 0x1e6e2fff) with your current image, then we could check the mac clock delay is correctly set.
You could use UART debug controller (datasheet section 11) if devmem is not available.
Thanks,
Troy Lee

Hi Troy,
If I got my devmem magic correct then this is the dump of that memory
region attached.
