APS 256VA ? help for identification

Wondering if anyone ever seen this device....

I bought this USED device on local online market
Usually this kind of used device comes here as recycle material, but they resale it again

the case made of aluminium, it has no label at all except MAC address
On the casing it says "APS 256 VA"
the one i got it say APS 256 VB on the PCB , the seller photo APS 256 VA on the PCB
("LONGDATA" also printed below asp256vb)

It has old CPU AR9344 rev 2, but
decent 16mb FLASH (it might be smaller, see note below)
128mb RAM
3G HSPDA PCIE.
2xUSB
2.4G 30dbm
1xWAN 2xLAN
12-48 VDC (may be support POE, not tested)
can be powered also with micro USB 5v 2A (tested)

note: there is indication that the FLASH was re-soldered, original maybe using smaller size flash

I can not find any information of it searching on google (on random language/region)
my guess it was use for internal only or inside bigger equipment.

the problem is the firmware...
(my guess) the seller flash it using SPI flasher using firmware base on TL-WDR3500 but poorly setup.
as a result, the buyers review complain about the wifi being unstable/not 30dbm

so for merely 5USD... i want to give it a try...

picture next....

some picture....

Anyone can help to identify it ?
i think it still got some potensial use....

One thing I read... the ART partition... I think it got lost during flashing.
Can I use ART from other device that use the same AR9344?
is this why the wifi is unreliable ?
sadly the seller said does not have the original firmware any longer...

If the above two lines are anything to go by then it's still supported: TP-Link TL-WDR3500. According the link only 8MB flash.

from U-Boot :
ar7240> flinfo

Bank # 1:
Model: Winbond W25Q128
JEDEC ID: ef4018
Capacity: 16 MB
Erase size: 64 KB
Clock: 22 MHz

As i mention on the post #1...
there are 2 posibilities :

  1. the firmware was built and tested on TL-WDR3500, and then copied transfer chip to chip directly using SPI chip programmer/flasher
  2. the firmware comes directly from openwrt.org and somehow install on the board.

Correct me if I am wrong.... I read somewhere on the documentation of openwrt... if you upgrade to the bigger Flash chip, openwrt will automatically detect and adjust accordingly.
(8mb firmware on to 16mb flash)

the problem is that ... i am not sure that the ART partition is being handle tranfer and handle correctly causing the WiFi radio unstable/unrealible

ART (Atheros Radio Test) - it contains calibration data for the wifi (EEPROM). If it is missing or corrupt, ath9k (wireless driver) won't come up anymore

I didn't ready through your post carefully enough, Sorry. After checking the internet for photos of the TP-Link device it was clear it's not exactly that device, and that you're well aware of the similarity to the TP-Link device.

I'm a bit out of my depth. So take what I write here after with tons of caution.

The wording regarding the ART indicates that it wouldn't even come up if missing or corrupted. So it may be just that the drivers are not very stable in the release of the running OpenWrt.

  • I would backup the partitions and save them away, just to be sure
  • Since the device works with exception of unstable WiFi I would check how similar the devicetree of your device is to the TP-Link. In my recent device the binary blob it /sys/firmware/fdt and that can be converted with the dtc utility. Comparing it to the TP-Link one, it would be interesting to see if the SPI interface is configured the same.
  • Try booting the current OpenWrt TP-Link initramfs from RAM using TFTP to see how well that image works with your hardware. Maybe the unstable WiFi in your currently running OpenWrt runs better with the current OpenWrt which surely contains a lot fixes for the components used in this device.
  • Backup the whole firmware is the first thing i try to figure out... the device has its "quirk". if i plug the serial TTL to PC first and then turn on the device... device will freeze with all LED on. So I have to turn on the device first and half second later plug the serialTTL to pc. I did backup from UBoot through httpd menu.

  • I will try figure out soon

  • Are you saying that i can use initramfs.bin and using Uboot to copy to RAM and boot on-the-fly?

you make me wonder if I might be wrong completely about the ART.... I got "the ART will affect Wifi" from Tool for Atheros ART partition

I trying to learn how to build standard firmware for this device. i had little left over knowledge of linux from wayback 20years ago. so bear with me....

I sorted out the supported hardware page.... i think Qxwlan E750G v8 look similar spec

Semi-correct for ar71xx, incorrect for ath79 (flash sizes and absolute partition offsets hard-coded in the DTS).

It has external RF amplifier chips, so you really need the correct ART for proper WiFi operation. All the other features except WiFi will work without ART though.

Are a quantity of these available? Any chance of finding one still with the original firmware?

It have 2 amplifier chip

Unfortunately the seller said they don't have one. As for quantity... Hard to guess(it's online store like ebay)

I planning to visit local market next week where recycle computer/network resale again.... See if i can find one

I plug the 3G module to laptop.

Mediatek Broadband 3G module.
Found partial windows update driver for it.

Any guide i can read how to boot initramfs from RAM?

The command available I'm able to use is bootm from the u-boot console, here a short help text on it. In my case I load the initramfs using a tftp server (and u-boot acts as a tftp client) to the device first.

In the Booting an initramfs image it's explained how to boot the recovery image.

I'm not sure if you could also use the USB port/USB stick to load the initramfs instead of TFTP.

Check the help command in uboot, if the usb sub system is available, the commands for it should be listed.

In many countries, the wireless companies have switched entirely to 4G, so 3G modems are not usable.

I was able to bootm....
using TL-WDR3500 and E750G initramfs
it seem normal boot, almost no error

what should i do next ?

lspci could be a good start.

To go on you would have to check the errors and see how relevant they may be.

And as @frollic mentioned use lspci (package pcituils) to check possible PCI devices, lsusb (package usbutils) for usb devices and mtdinfo check see information about the current flash storage layout.
