Trying, via http, with your files, do not work.
fullflash-asus.bin 16.384Kb
fullflash-padavan.bin 16.384Kb

Can you give me only fimware, without uboot ?

Tftp recovery works but this uboot start tftp server on router side so you need start tftp client on computer side. In file readme:

                             FEATURES

1. Press and hold the RESET button on Power-On: switch to Recovery mode. Use TFTP
   client or ASUS Firmware Restoration (device IP-address is 192.168.1.1). Also support
   Recovery from USB storage (not for all devices).
2. Press and hold the WPS button on Power-On: perform erase 'Config' partition (U-Boot
   Env & NVRAM) and self-reboot.

These files aren't intended for uboot recovery. Only for direct flashing with external programmer.
To get firmware see this message

92

Tanks Serge.
I'll try

About wifi map.
Can you give me it, and method for joint with uboot ?

But about 5ghz
I have not MT7610 chip on board.
I want to use USB key with MT7610
Can be same map and build ?

93

I have downloaded bin file.
Now uboot.bin is 159605 Byte (Need 196605byte)
MT7620_AP_2T2R-4L_internal_LNA_internal_PA_V15.bin is 512 byte (need 65535byte)
MT7610E-V10-FEM.bin is 512 byte (need 65535byte)

I have to add byte after, and add map, then add byte, then copy map ?

94

Padvan firmware, right upload, but do not work.

Maybe RAM do not Enought ?
I was wrong to put only 256Mbit, I do not know if I can change, is BGA.

95

You can overwrite any part of full flash dump (e.g. fullflash-asus.bin) with command:

  1. uboot (uboot.bin is your compiled uboot image file):
dd if=uboot.bin of=fullflash-asus.bin bs=1 seek=0 conv=notrunc
  1. Wifi calibration data (0x40000 = 262144):
dd if=MT7620_AP_2T2R-4L_internal_LNA_internal_PA_V15.bin of=fullflash-asus.bin bs=1 seek=262144 conv=notrunc

and so on.
If no mt7610e don't add MT7610E-V10-FEM.bin. If you use usb mt7610u no need MT7610E-V10-FEM.bin too.

I don't understand what you mean but see above method.

96

As you can see in bootlog:

MediaTek SoC: MT7620A, RevID: 0206, RAM: DDR2, XTAL: 20MHz
CPU/OCP/SYS frequency: 600/200/200 MHz
CPU revision is: 00019650 (MIPS 24KEc)
Determined physical RAM map:
 memory: 04000000 @ 00000000 (usable)

padavan firmware was compiled with incompatible settings (frequencies and memory). At least you need to recompile padavan firmware with your parameters.
BTW padavan and asus firmware don't support usb wifi adapters.
Usb wifi adapter may be used in openwrt.
Can you try this openwrt image for test?

97

After 200 seconds the LED stops flashing and the console never starts.
I thought only uboot would define the clock setup and memory.

openwrt first boot take long time because of making new flash filesystem.

Padavan firmware is highly optimized. It allow to change clocks too.
memory size can be forced in any kernel config.
I see that no start of bootlog. What is your uboot tty console speed? 115200 or 57600? I can correct linux kernel console speed to match speed of uboot.

99

Yesterday I redid uboot to 115200 because padvan was 57600
Today 115200 not math openwrt.
I have to put adapter after boot or crash terminal.
If it need I rebuild uboot for 57600, but what is for ??

100

I want see all bootlog.
I've rebuilt openwrt with console speed 115200. Pls reload and reflash.

101

This firts boot.
Now i send you secondo boot.
Consolle do not start.

Done!
HTTP ugrade is done! Rebooting...

Please press Enter to activate this console.

Pls reload and reflash.
