Xiaomi R3G (mt7603) kernel panic on ifconfig ra0 up

[djwlindenaar]

Hi, I've been trying to get the mt7603 module working on my mir3g setup, but no luck so far. After getting the required files in place, I get a kernel panic when issueing ifconfig ra0 up.

Anything I'm missing?

[nicefile]

this is working for mt7603 2.4Ghz radio: dd if=/dev/mtd3 of=/etc/wireless/mt7603/mt7603.eeprom.bin bs=1 count=200 modprobe mt7603 ifconfig ra0 up but don't get to excited . 5Ghz radio is useless unless proven wrong .

[djwlindenaar]

@nicefile Thanks for the tip, but sadly it did not resolve the issue.

The exact same oops and call trace.

Any other ideas?

BTW I notice the chip is called mt7603e in the open source driver. Is the e significant in this?
