+== VN10 LAN7430 EEPROM OTP not programmed
+
+Issue:
+ * A small number of GW7200-G and GW7201-G shipped between 2024-07-17 and 2024-09-16 did not have the LAN7430 (eth1 PCIe GbE controller) EEPROM programmed on the Gateworks test fixture. This causes the RJ45 LED's on eth1 to not be configured properly (will never illuminate) but otherwise the network device is fully functional.
+
+Resolution:
+ * You can manually program the LAN7430 EEPROM to correct this using ethtool which is on the default Ubuntu based firmware image by executing (can cut-and-paste) the following:
+{{{#!bash
+DEV=eth1
+ethtool --eeprom-dump eth1 offset 0 length 1 | tail -1 | grep f3 && echo "already programmed" && exit
+
+M1=$(hexdump -C /sys/devices/platform/soc@0/30800000.bus/30a30000.i2c/i2c-1/1-0052/eeprom | head -1 | cut -d" " -f8)
+M2=$(hexdump -C /sys/devices/platform/soc@0/30800000.bus/30a30000.i2c/i2c-1/1-0052/eeprom | head -1 | cut -d" " -f7)
