Getting Your Hardware Together + + Gather together this list of hardware items, which is not exhaustive. + Having these items ahead of time saves you from having to try and + collect hardware during development: + +Supported Starter + +* Kit Gen3 board with its 5V power supply. +* Micro USB-A cable for serial console. + This cable is optional if you are using Ethernet and an SSH connection. +* USB 2.0 Hub. The hub is optional but makes it easy to connect multiple USB devices. +* Ethernet cable. The cable is optional if you are using a serial console. +* HDMI type D (Micro connector) cable and an associated display. +* 4 Gbyte minimum MicroSD Card. It is recommended that you use a class 10 type. +* USB touch screen device such as the GeChic 1502i/1503i. A touch screen device is optional. + + **NOTE:** The Salvator-X Board has NDA restrictions. + Consequently, less documentation is available for this board both here and across the + Internet. + +## 4. Making Sure Your Build Environment is Correct + + The + "[Initializing Your Build Environment](../image-workflow-initialize-build-environment.html#Initializing-your-build-environment)" + section presented generic information for setting up your build environment + using the `aglsetup.sh` script. + If you are building an image for a supported Renesas board, + you need to take steps to make sure your build host is set up correctly. + +1. **Define Your Board:** + + Depending on your Renesas board, define and export a `MACHINE` variable as follows: + + | Board| `MACHINE` Setting | + |:-:|:-:| + | Starter Kit Pro/M3 | `MACHINE`=m3ulcb | + | Starter Kit Premier/H3 | `MACHINE`=h3ulcb | + | Salvator-X | `MACHINE`=h3-salvator-x | + + For example, the following command defines and exports the `MACHINE` variable + for the Starter Kit Pro/M3 Board: + + ```bash + export MACHINE=m3ulcb + ``` + +2. **Run the `aglsetup.sh` Script:** + + Use the following commands to run the AGL Setup script: + + ```bash + cd $AGL_TOP + source meta-agl/scripts/aglsetup.sh -m $MACHINE -b build agl-devel agl-demo agl-netboot agl-appfw-smack agl-localdev + ``` + + **NOTE:** + Running the `aglsetup.sh` script automatically places you in the + working directory (i.e. `$AGL_TOP/build`). + You can change this default behavior by adding the "-f" option to the + script's command line. + + In the previous command, the "-m" option sets your machine to the previously + defined `MACHINE` variable. + The "-b" option defines your Build Directory, which is the + default `$AGL_TOP/build`. + Finally, the AGL features are provided to support building the AGL Demo image + for the Renesas board. + + You can learn more about the AGL Features in the + "[Initializing Your Build Environment](../image-workflow-initialize-build-environment.html)" + section. + +3. **Examine the Script's Log:** + + Running the `aglsetup.sh` script creates the `setup.log` file, which is in + the `build/conf` folder. + You can examine this log to see the results of the script. + For example, suppose the graphics drivers were missing or could not be extracted + when you ran the script. + +<details> + <summary> In case of missing graphics drivers, you could notice an error message + similar to the following:</summary> + <pre> + <code> +[snip] +--- fragment /home/working/workspace_agl_master/meta-agl/templates/machine/h3ulcb/50_setup.sh +/home/working/workspace_agl_master /home/working/workspace_agl_master/build_gen3 +The graphics and multimedia acceleration packages for +the R-Car Gen3 board can be downloaded from: +https://www.renesas.com/en-us/solutions/automotive/rcar-demoboard-2.html + +These 2 files from there should be store in your'/home/devel/Downloads' directory. + R-Car_Gen3_Series_Evaluation_Software_Package_for_Linux-weston5-20190802.zip + R-Car_Gen3_Series_Evaluation_Software_Package_of_Linux_Drivers-weston5-20190802.zip +/home/working/workspace_agl_master/build_gen3 +--- fragment /home/working/workspace_agl_master/meta-agl/templates/base/99_setup_EULAconf.sh +--- end of setup script +OK +Generating setup file: /home/working/workspace_agl_master/build_gen3/agl-init-build-env ...

Checking Your Configuration + +Aside from environment variables and parameters you establish through +running the `aglsetup.sh` script, you can ensure your build's configuration +is just how you want it by examining the `local.conf` configuration file. + +You can find this configuration file in the Build Directory (e.g. +"$TOP_DIR/build/conf/local.conf"). + +In general, the defaults along with the configuration fragments the +`aglsetup.sh` script applies in the `local.conf` file are good enough. +However, you can customize aspects by editing the `local.conf` file. +See the +"[Customizing Your Build](../image-workflow-cust-build.html)" +section for common configurations you might want to consider. + +**NOTE:** For detailed explanations of the configurations you can make +in the ``local.conf`` file, consult the +[Yocto Project Documentation](https://www.yoctoproject.org/docs/). + +A quick way to see if you have the `$MACHINE` variable set correctly +is to use the following command: + +```bash +grep -w -e "^MACHINE =" $AGL_TOP/build/conf/local.conf +``` + +Depending on the Renesas board you are using, you should see output +as follows: + +```bash + MACHINE = "h3ulcb" +``` + +or + +```bash + MACHINE = "m3ulcb" +``` + +or + +```bash + MACHINE = "h3-salvator-x" +``` + +If you ran the `aglsetup.sh` script as described in the +"[Making Sure Your Build Environment is Correct](./renesas.html#4-making-sure-your-build-environment-is-correct)" +section earlier, the "agl-devel", "agl-demo", "agl-netboot", "agl-appfw-smack", and +"agl-localdev" AGL features will be in effect. +These features provide the following: + +* A debugger (gdb) +* Some tweaks, including a disabled root password +* A SFTP server +* The TCF Agent for easier application deployment and remote debugging +* Some extra system tools such as USB and bluetooth +* Support for the AGL demo platform +* Network boot support through TFTP and NBD protocols +* [IoT.bzh](https://iot.bzh/en/) Application Framework plus + [SMACK](https://en.wikipedia.org/wiki/Smack_(software)) and + [Cynara](https://wiki.tizen.org/Security:Cynara) +* Support for local development including `localdev.inc` when present + +## 6. Using BitBake + +This section shows the `bitbake` command used to build the AGL image. +Before running BitBake to start your build, it is good to be reminded that AGL +does provide pre-built images for developers that work with supported hardware. +You can find these pre-built images on the +[AGL Download web site](https://download.automotivelinux.org/AGL/release). + +For supported Renesas boards, the filenames have the following form: + +```bash +<release-name>/<release-number>/m3ulcb-nogfx/deploy/images/m3ulcb/Image-m3ulcb.bin +``` + +Start the build using the `bitbake` command. + +**NOTE:** An initial build can take many hours depending on your +CPU and and Internet connection speeds. +The build also takes approximately 100G-bytes of free disk space. + +For this example, the target is "agl-demo-platform": + +```bash + bitbake agl-demo-platform +``` + +The build process puts the resulting image in the Build Directory: + +```bash +<build_directory>/tmp/deploy/images/$MACHINE +``` + +## 7. Booting the Image Using a MicroSD Card + +To boot your image on the Renesas board, you need to do three things: + +1. Update all firmware on the board. +2. Prepare the MicroSD card to you can boot from it. +3. Boot the board. + +**NOTE:** For subsequent builds, you only have to re-write the MicroSD +card with a new image. + +### Updating the Board's Firmware + +Follow these steps to update the firmware: + +1. **Update the Sample Loader and MiniMonitor:** + + You only need to make these updates one time per device. + + Follow the procedure found on the + eLinux.org wiki to update to at least version 3.02, + which is mandatory to run the AGL image ([R-car loader update](https://elinux.org/R-Car/Boards/Kingfisher#How_to_update_of_Sample_Loader_and_MiniMonitor)). + +2. **Update the Firmware Stack:** + + You only need to update the firmware stack if you are + using the Eel or later (5.0) version of AGL software. + + M3 and H3 Renesas board are AArch64 platforms. + As such, they have a firmware stack that is divided across: **ARM Trusted Firmware**, **OP-Tee** and **U-Boot**. + + If you are using the Eel (5.0) version or later of the AGL software, you must update + the firmware using the **[h3ulcb][R-car h3ulcb firmware update](http://elinux.org/R-Car/Boards/H3SK#Flashing_firmware)** + or **[m3ulcb][R-car m3ulcb firmware update](https://elinux.org/R-Car/Boards/M3SK#Flashing_firmware)** links from the + [Embedded Linux Wiki](https://www.elinux.org/Main_Page) (i.e. `elinux.org`). + + The table in the wiki lists the files you need to flash the firmware. + You can find these files in the following directory: + + ```bash + $AGL_TOP/build/tmp/deploy/images/$MACHINE + ``` + + **NOTE:** The Salvator-X firmware update process is not documented on eLinux. + +### Preparing the MicroSD Card + +<details> + <summary> + Plug the MicroSD card into your Build Host. + After plugging in the device, use the `dmesg` command as follows to + discover the device name: + </summary> + <pre> + <code> +$ dmesg | tail -4 +[ 1971.462160] sd 6:0:0:0: [sdc] Mode Sense: 03 00 00 00 +[ 1971.462277] sd 6:0:0:0: [sdc] No Caching mode page found +[ 1971.462278] sd 6:0:0:0: [sdc] Assuming drive cache: write through +[ 1971.463870] sdc: sdc1 sdc2 + </code> + </pre> +</details> + +In the previous example, the MicroSD card is attached to the device `/dev/sdc`. + +<details> + <summary> + You can also use the `lsblk` command to show all your devices. + Here is an example that shows the MicroSD card as `/dev/sdc`: + </summary> + <pre> + <code> +$ lsblk + NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT + sda 8:0 0 167,7G 0 disk + ├─sda1 8:1 0 512M 0 part /boot/efi + ├─sda2 8:2 0 159,3G 0 part / + └─sda3 8:3 0 7,9G 0 part [SWAP] + sdb 8:16 0 931,5G 0 disk + └─sdb1 8:17 0 931,5G 0 part /media/storage + sdc 8:32 1 14,9G 0 disk + ├─sdc1 8:33 1 40M 0 part + └─sdc2 8:34 1 788M 0 part + </code> + </pre> +</details> + +**IMPORTANT NOTE:** Before re-writing any device on your Build Host, you need to +be sure you are actually writing to the removable MicroSD card and not some other +device. +Each computer is different and removable devices can change from time to time. +Consequently, you should repeat the previous operation with the MicroSD card to +confirm the device name every time you write to the card. + +To summarize this example so far, we have the following: + +* The first SATA drive is `/dev/sda`. + +* `/dev/sdc` corresponds to the MicroSD card, and is also marked as a removable device. + You can see this in the output of the `lsblk` command where "1" appears in the "RM" column + for that device. + +Now that you have identified the device you are going to be writing the image on, +you can use the `bmaptool` to copy the image to the MicroSD card. + +Your desktop system might offer a choice to mount the MicroSD automatically +in some directory. +For this example, assume that the MicroSD card mount directory is stored in the +`$SDCARD` variable. + +Following are example commands that write the image to the MicroSD card: + +```bash +cd $AGL_TOP/build/tmp/deploy/images/$MACHINE +bmaptool copy ./agl-demo-platform-$MACHINE.wic.xz $SDCARD +``` + +Alternatively, you can leave the image in an uncompressed state and write it +to the MicroSD card: + +```bash + sudo umount /dev/sdc + xzcat ./agl-demo-platform-$MACHINE.wic.xz | sudo dd of=$SDCARD bs=4M + sync +``` + +### Booting the Board + +Follow these steps to boot the board: + +1. Use the board's power switch to turn off the board. + +2. Insert the MicroSD card into the board. + +3. Verify that you have plugged in the following: + + * An external monitor into the board's HDMI port + + * An input device (e.g. keyboard, mouse, touchscreen, and so forth) into the board's USB ports. + +4. Use the board's power switch to turn on the board. + +After a few seconds, you will see the AGL splash screen on the display and you +will be able to log in at the console's terminal or using the graphic screen. + +## 8. Setting Up the Serial Console + +Setting up the Serial Console involves the following: + +* Installing a serial client on your build host +* Connecting your build host to your Renesas board's serial port +* Powering on the board to get a shell at the console +* Configuring U-Boot parameters +* Logging into the console +* Determining the board's IP address + +### Installing a Serial Client on Your Build Host + +You need to install a serial client on your build host. +Some examples are +[GNU Screen](https://en.wikipedia.org/wiki/GNU_Screen), +[picocom](https://linux.die.net/man/8/picocom), +and +[Minicom](https://en.wikipedia.org/wiki/Minicom). + +Of these three, "picocom" has less dependencies and is therefore +considered the "lightest" solution. + +### Connecting Your Build Host to Your Renesas Board's Serial Port + +You need to physically connect your build host to the Renesas board using +a USB cable from the host to the serial CP2102 USP port (i.e. Micro USB-A port) +on the Renesas board. + +<details> + <summary> + Once you connect the board, determine the device created for the serial link. + Use the ``dmesg`` command on your build host. + Here is an example: + </summary> + <pre> + <code> +dmesg | tail 9 +[2097783.287091] usb 2-1.5.3: new full-speed USB device number 24 using ehci-pci +[2097783.385857] usb 2-1.5.3: New USB device found, idVendor=0403, idProduct=6001 +[2097783.385862] usb 2-1.5.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 +[2097783.385864] usb 2-1.5.3: Product: FT232R USB UART +[2097783.385866] usb 2-1.5.3: Manufacturer: FTDI +[2097783.385867] usb 2-1.5.3: SerialNumber: AK04WWCE +[2097783.388288] ftdi_sio 2-1.5.3:1.0: FTDI USB Serial Device converter detected +[2097783.388330] usb 2-1.5.3: Detected FT232RL +[2097783.388658] usb 2-1.5.3: FTDI USB Serial Device converter now attached to ttyUSB0 + </code> + </pre> +</details> + +The device created is usually "/dev/ttyUSB0". +However, the number might vary depending on other USB serial ports connected to the host. + +To use the link, you need to launch the client. +Here are three commands, which vary based on the serial client, that show +how to launch the client: + +```bash +picocom -b 115200 /dev/ttyUSB0 +``` + +or + +```bash +minicom -b 115200 -D /dev/ttyUSB0 +``` + +or + +```bash +screen /dev/ttyUSB0 115200 +``` + +### Powering on the Board to Get a Shell at the Console + +Both the Pro and Premier kits (e.g. +[m3ulcb](https://elinux.org/R-Car/Boards/M3SK) and +[h3ulcb](https://elinux.org/R-Car/Boards/H3SK#Hardware)) have nine +switches (SW1 through SW9). +To power on the board, "short-press" SW8, which is the power switch. + +Following, is console output for the power on process for each kit: + +<details> + <summary> + h3ulcb: + </summary> + <pre> + <code> + +NOTICE: BL2: R-Car Gen3 Initial Program Loader(CA57) Rev.1.0.7 +NOTICE: BL2: PRR is R-Car H3 ES1.1 +NOTICE: BL2: LCM state is CM +NOTICE: BL2: DDR1600(rev.0.15) +NOTICE: BL2: DRAM Split is 4ch +NOTICE: BL2: QoS is Gfx Oriented(rev.0.30) +NOTICE: BL2: AVS setting succeeded.
