Got two sample subj units, looks promising, did anyone work on those yet?
Inside my unit:
- QCA9550-AT4A CPU with on-chip 3x3 WiFi, additional QCA8334-AL3C PHY and two W9751G6KB-25 RAM ICs
- QCA9890-BR4A Dual Band 3x3 WiFi on oversized miniPCI Board
- 2 MX25L12835F SPI Flash ICs
- I/O - USB 2.0, 2 LAN (1 POE), one standard console port (Cisco cable)
- Additional unpopulated JTAG and UART (J1 and J3)

Today got some things thing squared:
- Original partitions backed up
- QCA8334 switch is now configured with 2 inside ports in and two physical interfaces
- Both memory chips are detected
- Both radios are operational
- USB port is working
- Power LED is under control!
Open issues:
- Reset Button - can't find the right gpio. - tried exporting 0-31 and probing each while cycling the button...
- 2.4G WiFi LED - can't find the right gpio. Same as above cycling gpio to 0/1
Any ideas?
Opened the box and looked on the PCB again,
The power LED is dual color.
Stock firmware has a proprietary driver for LEDs...
Is there a way to properly reverse-engineer it from the firmware w/o sources?
"Properly"? 
I'd hope that there was already an upstream driver for whatever they've done.
Trying to figure out what that might be, I'd try:
lsmod- Examining the sysfs
- Extracting the root partition or looking through it on the device
-
stringson the firmware
Thanks Jeff,
Debugging these LEDs without jtag... 
The stock FW loads manufacturers’ console and linux is not accessible in their shell. Will try to mount it locally and search for stuff.
Another question - how to add SoC QCA9550 to the device tree? I understand it should be a simple patch as the SoC is generic to QCA955x family but I want the naming to be correct for future reference...
Did not find a way to get the other LEDs working, they seem to be hooked up to the switch, did not find a way to export or control it. I know that switch LEDs can be exported (it was present in 71xx on many devices) but none did it in ath79 for some reason.
Currently power is forever Orange (originally Green or Orange) and WiFi 2.4G is not working even though it is present as ath9k in LuCI.
