CPU : QCA9533-BL3A (MIPS 24Kc at 650 MHz, wifi bgn)
RAM : M14D5121632A -2.5B (ASK2) (64Mbytes de RAM DDR2-800 à 400Mhz)
ROM : G 25q64csig (BH1642) (8MBytes / 64MBit SPI Flash, 8Mb, SOIC-8)
other chips :
RS232 : zt1385leea (ethernet console port)
Ethernet : Group-Tek hst-2027dar ( 10/100BASE-TX TRANSFORMER MODULES) and hst-1025dr (10/100BASE-TX TRANSFORMER MODULES)

As you already noted, it's not listed in the Table of Hardware...are you asking for someone to work on bringing support for this device?

If so, can you also provide a boot log output of the serial console?

You haven't provided much information to begin (i.e. boot position configured in bootloader).

Hello,

Yes I'm asking for someone to work on bringing support for this device.

How can I get boot log output of the serial console ?

Where and how can I find boot position configured in bootloader ?

Thank you

Hello,

Yes I'm asking for someone to work on bringing support for this device.
Below the boot log output required for bringing support for this device.

Answer after a long time because I need to buy a serial console cable RJ45/ USB and find the good command line to show the boot log.
For each try, plug the cable USB connector in USB port in the computer, in a terminal launch the command line "sudo screen /dev/ttyUSB0 115200", go in TP Link admin web UI and launch Reboot, very quickly copy the output boot log in the terminal in a text editor.

The boot log output of the serial console:
