I'm trying to run OpenWrt(r48016) with ath10k driver on this device
(https://wikidevi.com/wiki/EnGenius_EAP1750H)

The calibration data is present at 0x5000 at ART. I've copied it to board.bin

But the driver fails to load:

The original QSDK version by EnGenius works good.
What am I doing wrong? Or the
board_file api 1 is not supported by ath10k?
