I have a custom board with WFX chip and WiFi scanning does not work most of the time. To perform the scan I am using `wpa_cli scan` command.
In 95% of the time this command return `FAIL-BUSY`. When happen I am getting following log from WFX kernel driver:
# wfx-sdio mmc2
1: hardware request START_SCAN (0x07) on vif 0 returned status 2
WFX driver version is `2.10`, kernel `4.1.52`.
Above issue is not observed on two others board I have, which are running the same code. Any ideas what can be the root cause of the issue?
