I just noticed my DIR-885L has some weird NVRAM format. Linux doesn't support it, it reads only part of it, which may affect brcmfmac.
There goes the most interesting part: 00000000 46 4c 53 48 50 3e 00 00 3f 01 00 00 4b 01 00 00 |FLSHP>..?...K...| 00000010 00 00 00 00 31 3a 70 61 35 67 38 30 61 33 3d 30 |....1:pa5g80a3=0| 00000020 78 31 64 36 36 2c 30 78 65 34 35 66 2c 30 78 32 |x1d66,0xe45f,0x2| 00000030 32 37 61 2c 30 78 32 33 36 65 2c 30 78 31 64 30 |27a,0x236e,0x1d0| 00000040 30 2c 30 78 65 62 38 38 2c 30 78 33 32 39 36 2c |0,0xeb88,0x3296,| (...) 00003e00 3d 36 35 35 33 35 00 31 3a 72 78 67 61 69 6e 65 |=65535.1:rxgaine| 00003e10 72 72 32 67 61 30 3d 36 33 00 30 3a 75 6c 62 70 |rr2ga0=63.0:ulbp| 00003e20 64 6f 66 66 73 35 67 62 34 61 31 3d 36 35 35 33 |doffs5gb4a1=6553| 00003e30 35 00 30 3a 6d 63 73 62 77 32 30 35 67 68 70 6f |5.0:mcsbw205ghpo| 00003e40 3d 32 38 35 38 38 33 35 39 36 38 00 00 00 00 00 |=2858835968.....| 00003e50 6f 66 66 73 65 74 32 30 69 6e 34 30 6d 32 67 3d |offset20in40m2g=| 00003e60 36 35 35 33 35 00 65 74 30 6d 61 63 61 64 64 72 |65535.et0macaddr| 00003e70 3d 30 30 3a 30 30 3a 30 30 3a 30 30 3a 30 30 3a |=00:00:00:00:00:| 00003e80 30 30 00 31 3a 72 78 67 61 69 6e 73 32 67 74 72 |00.1:rxgains2gtr| Header has length field 50 3e 00 00 which means 0x3e50 bytes. I was surprised to see more entries after then "end" of the NVRAM. What's interesting CFE (bootloader) also can't read these entries. Any idea what format is that? -- Rafał
