Checking dmesg in a Debian 13 running system from an existing rootfs I see: Qualcomm Atheros AR8031/AR8033 2188000.ethernet-1:01: attached PHY driver (mii_bus:phy_addr=2188000.ethernet-1:01, irq=POLL) So I think that adding this driver to the SD image should fix the issue.
hd-media SD card images do not contain network drivers. Network drivers are provided by nic*-modules udeb packages included in installation ISO images.
IIUC the driver for this PHY is at803x. It is included in nic-shared-modules udeb which is present in the netinst ISO image.
Maybe what is missing is the *ethernet* driver ? Can you find which one is used in the running system ?
