Hi, Some days ago I received a Xiaomi MiWiFi Mini and I've managed to run OpenWrt on it [1] (i.e. trunk OpenWrt, not the very modified stuff the vendor provides). I started with this initial patch [2] and I got the firmware running, but a couple of things are missing. I need some help with the .dts file (attached). The current status is:
Working: Ethernet, switch, SoC 802.11gbn radio, USB, TTL and sysupgrade
Partially working: MT7612E 802.11ac
Not working: LEDs and button
The problem with the 802.11ac radio is that I can not read the MAC from the
flash. I always get this message at boot time (with different MACs, of
course):
[ 14.560000] mt76pci 0000:01:00.0: Invalid MAC address, using random
address 96:a3:a5:fa:a9:2b
So far I've tried this:
pcie0 {
mt76@0,0 {
reg = <0x0000 0 0 0 0>;
device_type = "pci";
mediatek,mtd-eeprom = <&factory 0x8000>;
};
};
and also <&factory 0x0000> but the result is the same. I would say the
location is correct, because I see three consecutive MAC addresses in the
factory partition:
0x0004: 64:09:80:01:66:5D
0x0028: 64:09:80:01:66:5C
0x8004: 64:09:80:01:66:5E
that correspond respectively to SoC_radio, Ethernet and pcie_radio. The
question is, what is the way to make the mt76 driver use the MAC address
written in the flash?
Then, regarding the LEDs, I have tried enabling gpio chips 0, 1, 2 and 3,
exporting all the gpio numbers, setting the direction to "out" in all of
them and switching the values between 0, 1 and 255, but I can not control
any of the three leds (which are always on). The same problem for the reset
button, I can not find it anywhere. What else should I try?
Thank you very much!
Roger
