WL1837MOD: Wi-Fi device is not detected

akshi malhotra

Part Number: WL1837MOD
Other Parts Discussed in Thread: AM5728, , BEAGLEBOARD-X15, DRA752, TMP102, PMP, WL1271

Hello,

We are testing WL1837MOD evaluation card with AM5728 EVM. When the WiFi card is attached to EVM and system is booted, the card is not detected and system goes in hang state when an ifconfig or any other Wifi related command is given. We have to reboot the system but the problem persists.

Is there any diagnostic application available for resolving this issue?

What could be the possible problem? We have also tried reinserting the WiFi card.

Are you using TI processor SDK? Can, you please provide console logs?

Thanks
