DEPRECATED: Updated Linux drivers for the ATWILC1000/ATWILC3000 products are located at https://github.com/linux4microchip/linux/tree/master/drivers/net/wireless/microchip/wilc1000. To simplify development, the legacy Linux4WILC was merged into the Linux4Microchip repo where driver development continues (Please refer latest ATWILC1000/ATWILC 3000 Wi-Fi Link Controller Linux User Guide) Driver code for Microchip ATWILC Wireless Devices (ATWILC1000 & ATWILC3000)
I test wilc1000 and try to stop a wifi connection, and sometime I will see something like that:system report Oops and reboot auto, any idea for me? thanks very much!
