Hi all, I am having trouble building OpenWRT 21.02 with kernel 5.4 for Banana Pi R4 from Banana Pi R4 - SINOVOIP Github . . Build is failing with weird errors. Tried building from mediatek’s repo by following this guide as well but it is also failing with several errors. Can Anyone help me by sharing a working build setup or suggest any alternative way? I wanted kernel 5.4 in specific. Any help would be appreciated. Thanks
