Hi, I am working on support for the Meraki "underdog" APs in OpenWrt. The "underdog" APs appear to cover the models: Meraki MR20/GR10, and MR70/GR60. These APs require two special BDFs to get the Wi-Fi PHYs working. The bmi-board- id='s are not currently present in linux-firmware, so Wi-Fi is non-functional without them.
For the questions from the wiki page [1]:
* description for what hardware this is:
- IPQ4029 based boards
- one QCA40xx radio is used as 2.4GHz radio
- one QCA40xx radio is used as 5GHz radio
* origin of the board file (did you create it yourself or where you
downloaded)
- the files were extracted from the MR20 running a Meraki firmware
released in late 2024
* ids to be used with the board file (ATH10K_BD_IE_BOARD_NAME in ath10k)
- QCA4019 hw1.0
+ bus=ahb,bmi-chip-id=0,bmi-board-id=22,variant=Meraki-underdog.bin
sha256sum:
3b196ab4d5cf18ee194b2aafbdfb4b26b144c8f15875274168a4d721bcd6e313
+ bus=ahb,bmi-chip-id=0,bmi-board-id=23,variant=Meraki-underdog.bin
sha256sum:
ff5654adb55a6aa2ef6ba527090b551af62d5746b5cdc22f43d35b24827f6999
* attach the actual board file (board.bin)
- The name of the files are equal to the id string in the board-2.bin
(minus the ".bin")
Kind regards,
Hal Martin
