wilc1000 not properly working on SAMA5D3_XPLAINED board

[schb9]

hello,
wilc1000, wilc1000_sdio drivers or ATWILC1000 SD board do not properly start and work on my SAMA5D3_XPLAINED board

• built kernel for SAMA5D3_XPLAINED : Linux version 5.10.87 : this contains wilc1000... drivers

• used latest firmware files wilc1000_wifi_firmware-1.bin (placed into /lib/firmware/atmel/ as driver seems to load it from there and not from ./mchp directory as documented elsewhere !)

• when i load driver : 'modprobe wilc1000_sdio' journal reports

cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7'
platform regulatory.0: Direct firmware load for regulatory.db failed with error -2

any ideas or hints what might be wrong ?
