OK you have a Maxio MAE0621 ethernet chip. @Hqnicolas do you have any suggestions about the best way forward for this? Can I fork your armbian github and then try to create a PR to support MAE0621 (I haven't done this before)? Or try to make a dpkg for Maxio ethernet module install (difficult I think)?

@qwerty keyboard H313/H616/H618 are pretty much the same. A133 and A64 are different SOC’s. You don’t need the dts for the dram settings.

All the DRAM settings in the patch file are labeled for the H616, but I have the H313. Should I use the data from the H616 or H313 column from the DRAM setting extraction?

I can't seem to manage to extract the device tree because of garbage software stacks (Wtf is "gradle"? Doing everything in BrainF*ck as a joke would unironically be better) but I can atleast extract the DRAM settings! Just running sunxi-fw against the whole firmware image did the trick! @ 16: boot0: Allwinner boot0 size: 49152 bytes eGON checksum matches: 0xf6e7eb45 DRAM parameters: A64 H616 A133 DRAM clock : 600 600 600 DRAM type : 0x3 0x3 0x3 ZQ value : 0x3030303 - - ODT enabled : 0xe0e0e0e 0x1 - DX ODT : - 0x3030303 0x3030303 DX DRI : - 0xe0e0e0e 0xe0e0e0e CA DRI : - 0x1f12 0x1f12 PARA0 : - - 0x1 PARA1 : 0x1f12 0x30fb 0x30fb PARA2 : 0x1 0x8000000 0x8000000 MR0 : 0x30fb 0x1f14 0x1f14 MR1 : 0x8000000 0x4 0x4 MR2 : 0x1f14 0x20 0x20 MR3 : 0x4 0 0 TPR0 : 0x20 0xc0001002 0 TPR1 : 0 0x80000000 0 TPR2 : 0 0 0xc0001002 TPR3 : 0 0 0x80000000 TPR6 : 0 0x33808080 0x33808080 TPR10 : 0 0x2f1107 0x2f1107 TPR11 : 0 0xddddcccc 0xddddcccc TPR12 : 0xc0001002 0xeddc7665 0xeddc7665 TPR13 : 0x80000000 0x6041 0x6041 DRAM parameters 1: A64 H616 A133 DRAM clock : 600 600 600 DRAM type : 0x3 0x3 0x3 ZQ value : 0x3030303 - - ODT enabled : 0xe0e0e0e 0x1 - DX ODT : - 0x3030303 0x3030303 DX DRI : - 0xe0e0e0e 0xe0e0e0e CA DRI : - 0x1c12 0x1c12 PARA0 : - - 0x1 PARA1 : 0x1c12 0x30fb 0x30fb PARA2 : 0x1 0 0 MR0 : 0x30fb 0x840 0x840 MR1 : 0 0x4 0x4 MR2 : 0x840 0x8 0x8 MR3 : 0x4 0 0 TPR0 : 0x8 0xc0000a05 0 TPR2 : 0 0 0xc0000a05 TPR6 : 0 0x33808080 0x33808080 TPR10 : 0 0x2f0006 0x2f0006 TPR11 : 0 0xddddcccc 0xddddcccc TPR12 : 0xc0000a05 0xeddc7564 0xeddc7564 TPR13 : 0 0x40 0x40 DRAM parameters 2: A64 H616 A133 DRAM clock : 600 600 600 DRAM type : 0x3 0x3 0x3 ZQ value : 0x3030303 - - ODT enabled : 0xe0e0e0e 0x1 - DX ODT : - 0x3030303 0x3030303 DX DRI : - 0xe0e0e0e 0xe0e0e0e CA DRI : - 0x1c12 0x1c12 PARA0 : - - 0x1 PARA1 : 0x1c12 0x30fb 0x30fb PARA2 : 0x1 0 0 MR0 : 0x30fb 0x840 0x840 MR1 : 0 0x4 0x4 MR2 : 0x840 0x8 0x8 MR3 : 0x4 0 0 TPR0 : 0x8 0xc0000a05 0 TPR2 : 0 0 0xc0000a05 TPR6 : 0 0x33808080 0x33808080 TPR10 : 0 0x2f0006 0x2f0006 TPR11 : 0 0xddddcccc 0xddddcccc TPR12 : 0xc0000a05 0xeddc7564 0xeddc7564 TPR13 : 0 0x40 0x40 DRAM parameters 3: A64 H616 A133 DRAM clock : 600 600 600 DRAM type : 0x3 0x3 0x3 ZQ value : 0x3030303 - - ODT enabled : 0xe0e0e0e 0x1 - DX ODT : - 0x3030303 0x3030303 DX DRI : - 0xe0e0e0e 0xe0e0e0e CA DRI : - 0x1c12 0x1c12 PARA0 : - - 0x1 PARA1 : 0x1c12 0x30fb 0x30fb PARA2 : 0x1 0 0 MR0 : 0x30fb 0x840 0x840 MR1 : 0 0x4 0x4 MR2 : 0x840 0x8 0x8 MR3 : 0x4 0 0 TPR0 : 0x8 0xc0000a05 0 TPR2 : 0 0 0xc0000a05 TPR6 : 0 0x33808080 0x33808080 TPR10 : 0 0x2f0006 0x2f0006 TPR11 : 0 0xddddcccc 0xddddcccc TPR12 : 0xc0000a05 0xeddc7564 0xeddc7564 TPR13 : 0 0x40 0x40 DRAM parameters 4: A64 H616 A133 DRAM clock : 600 600 600 DRAM type : 0x3 0x3 0x3 ZQ value : 0x3030303 - - ODT enabled : 0xe0e0e0e 0x1 - DX ODT : - 0x3030303 0x3030303 DX DRI : - 0xe0e0e0e 0xe0e0e0e CA DRI : - 0x1c12 0x1c12 PARA0 : - - 0x1 PARA1 : 0x1c12 0x30fb 0x30fb PARA2 : 0x1 0 0 MR0 : 0x30fb 0x840 0x840 MR1 : 0 0x4 0x4 MR2 : 0x840 0x8 0x8 MR3 : 0x4 0 0 TPR0 : 0x8 0xc0000a05 0 TPR2 : 0 0 0xc0000a05 TPR6 : 0 0x33808080 0x33808080 TPR10 : 0 0x2f0006 0x2f0006 TPR11 : 0 0xddddcccc 0xddddcccc TPR12 : 0xc0000a05 0xeddc7564 0xeddc7564 TPR13 : 0 0x40 0x40 DRAM parameters 5: A64 H616 A133 DRAM clock : 600 600 600 DRAM type : 0x3 0x3 0x3 ZQ value : 0x3030303 - - ODT enabled : 0xe0e0e0e 0x1 - DX ODT : - 0x3030303 0x3030303 DX DRI : - 0xe0e0e0e 0xe0e0e0e CA DRI : - 0x1c12 0x1c12 PARA0 : - - 0x1 PARA1 : 0x1c12 0x30fb 0x30fb PARA2 : 0x1 0 0 MR0 : 0x30fb 0x840 0x840 MR1 : 0 0x4 0x4 MR2 : 0x840 0x8 0x8 MR3 : 0x4 0 0 TPR0 : 0x8 0xc0000a05 0 TPR2 : 0 0 0xc0000a05 TPR6 : 0 0x33808080 0x33808080 TPR10 : 0 0x2f0006 0x2f0006 TPR11 : 0 0xddddcccc 0xddddcccc TPR12 : 0xc0000a05 0xeddc7564 0xeddc7564 TPR13 : 0 0x40 0x40 DRAM parameters 6: A64 H616 A133 DRAM clock : 600 600 600 DRAM type : 0x3 0x3 0x3 ZQ value : 0x3030303 - - ODT enabled : 0xe0e0e0e 0x1 - DX ODT : - 0x3030303 0x3030303 DX DRI : - 0xe0e0e0e 0xe0e0e0e CA DRI : - 0x1c12 0x1c12 PARA0 : - - 0x1 PARA1 : 0x1c12 0x30fb 0x30fb PARA2 : 0x1 0 0 MR0 : 0x30fb 0x840 0x840 MR1 : 0 0x4 0x4 MR2 : 0x840 0x8 0x8 MR3 : 0x4 0 0 TPR0 : 0x8 0xc0000a05 0 TPR2 : 0 0 0xc0000a05 TPR6 : 0 0x33808080 0x33808080 TPR10 : 0 0x2f0006 0x2f0006 TPR11 : 0 0xddddcccc 0xddddcccc TPR12 : 0xc0000a05 0xeddc7564 0xeddc7564 TPR13 : 0 0x40 0x40 DRAM parameters 7: A64 H616 A133 DRAM clock : 600 600 600 DRAM type : 0x3 0x3 0x3 ZQ value : 0x3030303 - - ODT enabled : 0xe0e0e0e 0x1 - DX ODT : - 0x3030303 0x3030303 DX DRI : - 0xe0e0e0e 0xe0e0e0e CA DRI : - 0x1f12 0x1f12 PARA0 : - - 0x1 PARA1 : 0x1f12 0x30fb 0x30fb PARA2 : 0x1 0 0 MR0 : 0x30fb 0x840 0x840 MR1 : 0 0x4 0x4 MR2 : 0x840 0x8 0x8 MR3 : 0x4 0 0 TPR0 : 0x8 0xc0001002 0 TPR2 : 0 0 0xc0001002 TPR6 : 0 0x33808080 0x33808080 TPR10 : 0 0x2f1107 0x2f1107 TPR11 : 0 0xddddcccc 0xddddcccc TPR12 : 0xc0001002 0xeddc7665 0xeddc7665 TPR13 : 0 0x40 0x40

One interface is for STA (client mode / normal wireless) and one for AP (access point, where you connect to) or P2P (Wi-Fi Direct). Some firmware / drivers enables this by default. Usually it is in Makefile (just example https://github.com/armbian/rtl8723ds/blob/main/Makefile) but it could also be deep in the code. Don't know.
