Hi, by coincidence, I've learned that label MAC addresses on Ubiquiti devices aren't correct anymore after switching from phy0 to "expected" flash locations in this patch: https://github.com/openwrt/openwrt/commit/d421a8b9448968de0e3265f5beb469c210a909ab
I've investigated that on a Ubiquiti Picostation M (ar71xx, I just happened to have access to that): The phy seems to get calibration data from EEPROM 0x1000 (note that bullet-m image is used): ar71xx: https://github.com/openwrt/openwrt/blob/master/target/linux/ar71xx/files/arch/mips/ath79/mach-ubnt-xm.c#L97 ath79: https://github.com/openwrt/openwrt/blob/master/target/linux/ath79/generic/base-files/etc/hotplug.d/firmware/10-ath9k-eeprom#L88 No explicit MAC address overwrite takes places. The phy0 MAC address on the device is set up correctly. However, when I manually try to find the address in the EEPROM partition, I find it twice, with the following locations: mtd_get_mac_binary EEPROM 0x120c mtd_get_mac_binary EEPROM 0xa0bf I expected it to be at 0x1002 where it is typically put by ath9k_patch_mac (offset +2). However, I've found at least one reference to the first actual location in 10-ath9k-eeprom, for dlink,dir-825-b1: ath9k_patch_mac_crc $(mtd_get_mac_text "caldata" 0xffa0) 0x20c So, can someone enlighten me what the correct location (offset 0x2 vs. 0x20c) depends on? Thanks Adrian
