# Introduction This guide demonstrates how to quickly setup the EVM and the experience out-of-box audio demos on the AM62D Audio evaluation module (EVM). This can be done from any PC platform (Windows or Linux). # Hardware Setup In addition to the AM62D EVM itself, the following hardware is needed: * USB Type-C 20W power supply ( Make sure to use type-C to type-C cable ). * USB Micro-B cable for UART serial communication * Any audio device with input microphone, output speaker and 3.5mm audio jack (Needed for running MCASP examples) * Note : Apple earphones are not supported. * Micro-SD card (8GB or larger recommended) * Ethernet cable for tuning interface * Note : The ethernet expansion board needs to be attached separately  [[b! USB Type-C Ports There are 2 USB Type-C ports on the EVM. The one next to the USB Micro-B port is marked as "Type-C DRP" and can be used for data communication and power supply. The other one is marked as "Type-C PWR" and is only used for power supply. ]] # Host PC Requirements * Windows PC * Windows 10 64 bit * Minimum 4GB, >8GB RAM recommended * At least 10GB of hard disk space * Linux PC * Ubuntu 22.04 64bit or higher * Minimum 4GB, >8GB RAM recommended * At least 10GB of hard disk space # Audio-SDK Setup This section walks through the steps needed to run the prebuilt binaries on the AM62D EVM and connecting it to Audio Weaver ## Format SD card ### Windows Platform * Start `diskpart` in run-box * Type `list disk` and then press Enter. * Type `select disk [n]` and press Enter. n - represents the disk number of your bootable SD card * Type `clean` and then press Enter * Type `create partition primary` and then press Enter. * Type `format fs=fat32 quick` and then press Enter to format SD card. * Type `list volume` and then press Enter. * Type `select volume [n]` and press Enter. n - represents the primary partition number you created. * Type `active` and then press enter. ( This will enable the bootable flag for this partition ) * Type `exit` and then press Enter. ### Linux Platform * Connect the micro SD card to the PC using any card reader * Check if it's detected by either using the sudo dmesg command or the `lsblk` command * Unmount any mounted partitions using the `umount` command * Launch the fdisk utitility. `sudo fdisk [/dev/mmcblk0]` * Delete all the existing partitions using fdisk utility, option `d` * Create new partition using option `n` * Make the first partition as bootable by setting the BOOT flag, option `a` * Format the first partition with FAT32, option t. Hex code or alias (type L to list all): `c` * Write all the changes ## Flash Prebuilt Binaries to SD card The <a href="https://www.ti.com/secureresources/AM62D-RESTRICTED-SW" target="blank">release</a> provides prebuilt binaries which have been tested in SD boot mode. * The prebuilt binaries are located at: `sdk_install_loc/bin/am62dx/sd_card` * Format the micro-sd card in FAT filesystem. Refer Format bootable SD card section. * Copy the below mentioned prebuilt binaries to the micro-sd card. * `tiboot3.bin` : SD Card bootloader * `dm` : System firmware which runs on Wakeup R5F * `app` : Tuning gateway application which runs on MCU/R5F * `app_dsp` : The DSP application which runs on C7x and includes AWECore ## Establishing a Serial Connection with the EVM Use a USB Micro-B cable to connect the host PC to the USB Micro-B interface for UART on the EVM. Open a serial port console on the host PC, according to procedures described below for Linux or Windows. When the serial console opens, it will be blank until the EVM powers up. ### Connecting with Linux 1. Determine the serial device names associated with the EVM by running the following command on the Linux PC:<br> ``` dmesg | grep ttyUSB ``` <br>You should see results similar to this: ``` [ 8383.599799] usb 2-1.3: FTDI USB Serial Device converter now attached to ttyUSB0 [ 8383.600472] usb 2-1.3: FTDI USB Serial Device converter now attached to ttyUSB1 [ 8383.600884] usb 2-1.3: FTDI USB Serial Device converter now attached to ttyUSB2 [ 8383.601265] usb 2-1.3: FTDI USB Serial Device converter now attached to ttyUSB3 ``` <br>This means the EVM has four serial ports. The second one is to be used for boot logs. 2. Use the following command to open a serial port console<br> ``` screen /dev/ttyUSB1 115200 ``` ### Connecting with Windows 1. Open Windows Device Manager and it should show 4 COM ports associated with the EVM, similar to below:<br> <img src="./images/am62dx/COM_ports.png" alt="COM Ports" style="width:80%; height:auto;"> 2. Use a serial terminal emulator such as TeraTerm to connect to the first port. Connect to the **second COM port** to view the boot logs. Configure the serial port setting to 115200 baud rate, 8 bit, no parity, 1 stop bit, no flow control, as shown below: <img src="./images/am62dx/Tera_term.png" alt="TeraTerm" style="width:60%; height:auto;"> ## Run Audio-SDK on the EVM <span id="SD_boot"></span> * Insert the flashed SD card in EVM SD-CARD slot. Refer Flash Prebuilt Binaries to SD card section for flashing the prebuilt binaries. * Set the board in SD boot mode and powercycle the board <br> BOOTMODE [ 8 : 15 ] (SW1) = 0100 0000 <br> BOOTMODE [ 0 : 7 ] (SW2) = 1100 0010  * Connect Terminal using UART port (second of 4 ports). Refer <a href="http://swubn04.india.englab.ti.com/mcu_plus_sdk/sitmpurtos_nightly_mcu_plus_sdk_am62dx/latest/artifacts/output/webgen/exports/docs/api_guide_am62dx/EVM_SETUP_PAGE.html#CCS_UART_TERMINAL"> Setup UART Terminal page </a> for details. * After power cycle, the console will print ip-address. Use the ip-address for AWEServer/AWEDesigner. The console output should like below. <span id="boot_logs"></span>  ## Steps to run AWE application <span id="AWE_connection"></span> * Open UART console and check for ip-address as shown in the above figure. * On Windows computer, launch <a href="https://21088554.fs1.hubspotusercontent-na1.net/hubfs/21088554/AWE_Designer_8.D.2.6_Standard.exe" target="blank"> AWE Server </a>. * Connect using TCP/IP with IP address given by DHCP server <br> Click on Target -> Change Connection -> Enter IP address * Connect AWE server to AM62D <br> <img src="./images/am62dx/AWE_connect_ethernet.png" alt="AWE_connect_ethernet" style="width:60%; height:auto;"> * Click on **connect** checkbox if it does not connect automatically * Now launch Awe Designer and open the layout file and press 'Launch icon'. * You should now be able to see your application running. It should look something like the below fig.  # Next Steps * Complete the MCU+SDK Getting Started Guide * Run sample examples on AM62D * Review Developer guides for AM62D * Subscribe to MCU+SDK release notifications * Browse MCU+SDK resources on TI Resource Explorer # Troubleshooting Here we list some common problems which may happen during this exercise and the corresponding solutions: 1. **The EVM doesn't power up and no LEDs are illuminated after connecting the USB-C power cable.**<br> This is usually caused by not having the right power supply. Please make sure a USB-C power adapter is used. A USB to USB-C cable will not work. Please refer to the <a href="#hardware-setup">AM62D Audio EVM User's Guide</a> for recommended external power supply</a>. 2. **The EVM is connected to the PC, but the PC doesn't recognize the device.**<br> This may be caused by connecting to the wrong port on the EVM. Please make sure you connect to the USB Micro-B connector right next to the two USB-C connectors. Please refer to <a href="#hardware-setup">Hardware Setup</a>. 3. **EVM fails to boot**<br><span id="EVM_lights"></span> Make sure the EVM is set to SD boot mode.<br> Ensure the marked LEDs are glowing as shown in the below image.  4. **AWE server fails to connect**<br> Make sure that the following requirements are satisfied. * The <a href="#EVM_lights">marked LEDs</a> are glowing. * EVM is set to <a href="#SD_boot">SD boot mode</a>. * The ethernet cable is connected to the EVM. * The boot logs should be similar to <a href="#boot_logs">this</a>. * The DM logs(3rd COM port of the 4 ports) should look like the below fig.  * The fields in <a href="#AWE_connection">AWE target connection</a> is configured correctly. * Verify that the SBL, R5 app, and C7x app are executing correctly by opening their corresponding terminals.
