Hi
We are using wl18xx (wifi + BT) module for our custom board,
In one of our custom board we are facing an issue, when the wlan0 tries to acquire IP we could see some interrupt messages on the console ,
While probing the interrupt line during these error occurs we were able to see some activity on the interrupt line of wl1835.
What might be the issue?
Note: We tested the same SD on another boards and seems working fine,
The output on the console is as follows...
