Hello vsb

Based on your answers  provided in the other thread, for which I am thankful for, I have additional questions:

In the imx6ul-evk-btwifi.dtsi file, it mentions in the comments that

" This DTS file is written for plugging in Murata Wi-Fi/BT EVK into Slot * SD1 and using Murata i.MX InterConnect Ver 2.0 Adapter. Bluetooth UART & control signals are connected via ribbon cable (J1701 connector)."

However, I've noticed that the pin control for wlreg_on is gpio5_1 [MX6UL_PAD_SNVS_TAMPER1__GPIO5_IO01] which is not wired to imx6ul-EVK J1701.

  1. Can you elaborate on how the 4343 WLREG_ON is controlled?
  2. Is WL_HOST_WAKE requied for the bcmdhd driver.

Thanks in advance for your help.

Some hardware modifications are required for OOB operation on iMX6UL which requires WL_HOST_AWAKE to be hooked up.

But these modification are not required for non OOB operation, which is the default mode of operation.

The modification required are mentioned in "Murata Wi-Fi/BT EVK for i.MX6 Hardware User Manual 1.0 ". After you register with Murata you can get them at:
