# Getting started Source: [https://docs.qualcomm.com/doc/80-70014-14/topic/get_started.html](https://docs.qualcomm.com/doc/80-70014-14/topic/get_started.html) This information describes the prerequisites, such as setting up an SSH connection and verifying and storing Media Access Control (MAC) address, required to bring up WLAN functionality. Before you begin, see [Qualcomm Linux Build Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70014-254/introduction.html) for common infrastructure setup and build workflows. ## Set up UART/SSH Source: [https://docs.qualcomm.com/doc/80-70014-14/topic/get_started.html](https://docs.qualcomm.com/doc/80-70014-14/topic/get_started.html) ### About this task To set up debug Universal Asynchronous Receiver/Transmitter (UART) and Wi-Fi, and to connect to Secure Socket Shell (SSH), see the [Qualcomm® RB3 Gen 2 Quick Start Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70014-253/set_up_the_device.html). Note: A password prompt is displayed while using Secure Copy Protocol (SCP) to transfer any file from/to a device. Enter oelinux123 in the password field. ## Set MAC address Source: [https://docs.qualcomm.com/doc/80-70014-14/topic/get_started.html](https://docs.qualcomm.com/doc/80-70014-14/topic/get_started.html) ### About this task To set a unique MAC address for the Wi-Fi interface, perform the following steps in debug UART serial console: Note: The configured MAC address is persistent across each boot cycle until the new image is flashed. Set the MAC address after flashing a new image, or while setting up the RB3 Gen2 device for the first time. ### Procedure 1. Ensure that the device is connected to the host over UART by performing the steps listed in the [Qualcomm® RB3 Gen 2 Quick Start Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70014-253/set_up_the_device.html). 2. To enable Permissive mode and to allow read/write access run the following command: setenforce 0Copy to clipboard mount -o rw,remount /Copy to clipboard 3. Create a wlan\_mac.bin file in the /lib/firmware/wlan/qca\_cld/ folder by running the following commands: cd /lib/firmware/wlan/qca_cld/Copy to clipboard vi /lib/firmware/wlan/qca_cld/wlan_mac.binCopy to clipboard Note: There is no default wlan\_mac.bin file. 4. Enter the following MAC address in wlan\_mac.bin using the following format: Intf0MacAddress= Intf1MacAddress= Intf2MacAddress= Intf3MacAddress= ENDCopy to clipboard For example, Intf0MacAddress=000AF58989FF Intf1MacAddress=000AF58989FE Intf2MacAddress=000AF58989FD Intf3MacAddress=000AF58989FC ENDCopy to clipboard Note: Save the wlan\_mac.bin file. 5. To get read/write/executable permission for wlan\_mac.bin, run the following command: chmod 777 wlan_mac.bin Copy to clipboard
