I came onto a Trendnet TEW-827DRU Version 2 that is MT7621an with
MT7615E x 2 wifi chips. I was able to get UART output and stock has
these partitions:

I reviewed all the mt7621 *dts files and none have an art_block.
grep -rn "art_block" target/linux/ramips/dts/
target/linux/ramips/dts/mt7621_elecom_wrc-1900gst.dts:31: label =
"art_block";
target/linux/ramips/dts/mt7621_elecom_wrc-2533gst.dts:30: label =
"art_block";
target/linux/ramips/dts/mt7621_elecom_wrc-1750gs.dts:31: label =
"art_block";
My understanding is that for Qualcomm, the art* partition contains
Atheros calibration data. I'm lost as to what and art_block is on a
mediatek device. Trendnet can be lazy with partition naming - the
TEW-810 has a partion referred to a D-Link.
Does this partition contain any data or is empty? I suppose you can just
ignore it (keep it as read-only), it looks like copy&paste mistake made
by original board manufacturer.

I did find a "firmware2" partition -
mt7621_asus_rt-acx5p.dtsi, a "second_config" - mt7621_mtc_wr1201.dts
that are about the same size and position.
Are there any Mediatek experts that can enlighten me and point me in the
right direction?
Thanks in advance
