Add support for Mikrotik hAP ax Lite

Is there any info about adding openwrt support for MikroTik hAP ax Lite?

Looks like it has 256MB RAM. Same as Fritz!Repeater 1200AX with the same IPQ5010. So the chances are quite low as far as I know.

Just for the record I am playing with this device;

Has a 32mbit (4MB) 1.8v SPI NOR flash for boot etc, and a 128MByte SPI NAND flash (appears to be on different SPI bus)

10-pin UART header on the board has: (SPI is the NOR boot SPI bus)

NOTE everything is 1.8v!
4=SPI /WE (not sure - is at 1v8)
6=RX (NOTE 1.8v!)
7=TX (NOTE 1.8v!)

The RX/TX normally are just idle, there is no boot message nor do they do anything if you enable them in the Mikrotik OS as a console.

However the same trick on other Mikrotik IPQ routers does bring them alive:
I desoldered and read the NOR flash, looked for the "Hard" partition, and found the uart enable parameter.
At offset 0x210048 there is the byte sequence:
15 00 04 00 01 00 28 08
change this to
15 00 04 00 00 00 28 08
and you get RouterBoot messages and console. You don't get Kernel bootup messages without further fiddling, but this is a start...

RouterBOOT booter 7.8


CPU frequency: 800 MHz
  Memory size: 256 MiB
    NAND size: 128 MiB

Once the serial port is enabled as above (IDK yet of any other way than editing the NOR flash chip), the usual Mikrotik RouterOS serial stuff works on the serial port, e.g.

/system console disable 0
/port set serial0 baud-rate=19200 data-bits=8 parity=none stop-bits=1
/system serial-terminal serial0

This first disables the default RouterOS console on that port, then sets baud, then lets you just type stuff and see it come out of the serial port.

Obviously this a 256MB RAM unit (the RAM is onchip on the SOC) so Ath11k yadda yadda.
HOWEVER note that 8devices have a QSDK (Qualcomm's fork) of OpenWRT build on their wiki for the IPQ5000 and a suitable UBoot
This ^^ image is I believe set up for NOR flash so one could in theory flash this onto e.g. a 16MByte SPI flash (note; must be 1.8v compatible chip) and ignore the NAND onboard. 8devices provide a ready-built binary image but it's also possible to build your own given the provided instructions, and this produces both an IPQ5000 and 5010 binary. USB kernel modules are included.

Note this is an IPQ5010 which has USB. It has an LGA footprint on the underside of the PCB to solder in a modem. The footprint is for an FG621 modem, with a USB connection to the IPQ CPU.

The USB 2 HS pads are accessible here:


Note however (to get USB) that they have also non-pop'ed two resistors on the topside of the board so these USB pads are not connected; you will want to bridge these two solderpoints on the topside of the board (just above the silkscreened logo, below the IPQ)

This is the pinout for the modem pads, this clearly matches up what is visible on the PCB

There is (unpopulated) traces/pads for the SIM card connector.

No particular reason, just FYI ; socketed flash, UART...
