I have a modified 16MB flash wdr4900v2, I installed 18.06.4 and it works well.
I want to test the snapshot ath79 branch to have offload feature but have no wireless.
It seems that the current snapshot ath79 does not take into account the flash size.
the ART partition is located at 0x7f0000 instead of 0xff0000 as the 18.06.4 does.
here is is kernel log
