We want to have our ICSSG1 talking to a PHY. We build 'firmware/icss_dualmac' in git.ti.com/.../k3-image-gen (Commit 3b4a2007a54db72d8814ecbb2555392863c24935). It works fine for a RGMII connection to a PHY. Now we have an MII connection. Therefore we build the firmware with the makefile patched¹ to talk MII. RX seems to work (ethtool reports valid rx packages²), but TX does not. In firmware/icss_dualmac/src/rxl2_txl2.asm:61 I found the comment "MII : set up for MII mode (RX ok, TX not tested)". So I guess TX is not expected to work with this firmware? I also found that this firmware moved (git.ti.com/.../pdk, packages/ti/drv/emac/firmware/icss_dualmac), but the issue remains.
Is there any PRU MAC firmware out there that talks MII?
Thanks!
