Hi guys!
I'm looking for an owner of TP-LINK WA701ND v1, because I need a log of the CONFIG and ART partition:
0x003e0000-0x003f0000 : "config"
0x003f0000-0x00400000 : "art"
I have unintentionally deleted the flash, and so, I have down the WiFi connection using OpenWrt, because I deleted the configuration data of this device.
As written in
https://wiki.openwrt.org/doc/howto/rest … _partition
I have only a possibility to re-live my AP using a backup of this part of the memory .
Please, help me !

TY
Gino

I found, for WR741ND (in the file TL-WR741ND_V2.1_W25Q32B_Unlock.BIN) valid data starting 3F1000 up to 3F11FF, that is in the ART partition.
Someone knows read these data ? Any ideas ?

Hi all.
I confirm that the ART partition that I previous posted is correct !!! I flashed the data in WA701ND v1, et voilà ....
Now all is on. I am very happy. I hope that this thread can help someone else.
Ciao

Nice to know calibration data is not something unique to particular device.
Config partition is probably not needed. I guess it contain settings for original firmware.
In all routers I've seen calibration data was 64K and called either "art" or "caldata"
