Chapter 2 Hardware Configuration

This section contains general information about:

  • Installations
  • Jumper and connectors

2.1.1 Mini-PCIe & M.2 Cards Installation
To install the mini-PCIe & NGFF M.2 card, remove the device cover first as mentioned above, locate the slot inside the device, and perform the following steps.
1) Align the keys of the mini-PCIe card with that of the mini-PCIe interface, and insert the card slantwise. (Insert the M.2 card in the same way.)

FIG 11 Hardware Configuration.JPG

2) Push the mini-PCIe card downwards as shown in the picture below, and fix it onto the brass standoff with a screw.
(Fix the M.2 card also with one screw.)

FIG 12 Hardware Configuration.JPG

2.2.1 Setting the Jumpers
Configure your device by using jumpers to enable the features that you need based on your applications. Contact your supplier if you have doubts about the best configuration for your use.

2.2.2 How to Set Jumpers
Jumpers are short-length conductors consisting of several metal pins with a base mounted on the circuit board. Jumper caps are placed (or removed) on the pins to enable or disable functions or features. If a jumper has 3 pins, you can connect Pin 1 with Pin 2 or Pin 2 with Pin 3 by shorting the jumper.

FIG 13 How to Set Jumpers.JPG

Refer to the illustration below to set jumpers.

FIG 14 How to Set Jumpers.JPG

When two pins of a jumper are encased in a jumper cap, this jumper is closed, i.e. turned On.
When a jumper cap is removed from two jumper pins, this jumper is open, i.e. turned Off.

Chapter 3 Software Setup

This chapter introduces the following setup on the device: (for advanced users only)

  • Make a recovery SD card
  • Upgrade firmware through the recovery SD card

3.1 Make a Recovery SD Card
Note: This is for advanced users who has IBASE standard image file only.
Basically, IBR215 is preloaded with O.S (Android or Yocto) into eMMC by default. Connect the HDMI with IBR215, and 12V-24V power directly.
This chapter guides you to make a recovery boot-up microSD card.

3.1.1 Preparing the Recovery SD card to Install Linux / Android image into eMMC
Note: All data in the eMMC will be erased.

1) System requirements:
Operating System: Windows 7 or later Tool: uuu SD card: 4GB or greater in size
2) Insert your SD card to this board (i.e. the P1 connector), connect the board to PC through the mini-USB port (i.e. the P4 connector), and change the boot mode to download mode.

FIG 47 Make a Recovery SD Card.jpg

3) boot IBR215 and flash SD via CMD command “uuu.exe uuu-sdcard.auto” or double click “FW_down-sdcard.bat” (Same way as PCBA update)

FIG 48 Make a Recovery SD Card.jpg

3.1.2 Upgrade Firmware through the Recovery SD Card
1) Put recovery files into USB flash disk (FAT32)
A> Yocto/Ubuntu: Copy all recovery files into PATH:

FIG 49 Upgrade Firmware through the Recovery SD Card.JPG

FIG 50 Upgrade Firmware through the Recovery SD Card.JPG

2) Plug (step1)SD and (step2)USB flash disk into IBR215
3) Normal boot IBR215 (SW1 Pin1 OFF), start recovery eMMC automatically.
4) The update information will show on HDMI.

Chapter 4 BSP Source Guide

This chapter is dedicated for advanced software engineers only to build BSP source. The topics covered in this chapter are as follows:

  • Preparation
  • Building release
  • Installing release to board

4.1 Building BSP Source
4.1.1 Preparation
The recommended minimum Ubuntu version is 18.04 or later.
1) Install necessary packages before building:

sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \
xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev \
pylint3 xterm

2) Donwload toolchain

The clang used to compile Linux kernel needs to be a newer version. Perform the following steps to set the clang to be used to compile Linux kernel: sudo git clone https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86 /opt/ prebuiltandroid-clang -b master cd /opt/prebuilt-android-clang
sudo git checkout 007c96f100c5322acc37b84669c032c0121e68d0 export CLANG_PATH=/opt/prebuilt-android-clang

The preceding export commands can be added to “/etc/profile”. When the host boots up,
“AARCH64_GCC_CROSS_COMPILE” and “CLANG_PATH” are set and can be directly used.
乙、Prepare the build environment for U-Boot and Linux kernel.
This step is mandatory because there is no GCC cross-compile tool chain in the one in AOSP codebase.
a. Download the tool chain for the A-profile architecture on arm Developer GNU-A Downloads page. It is recommended
to use the 8.3 version for this release. You can download the “gcc-arm-8.3-2019.03-x86_64-aarch64- elf.tar.xz” or “gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz”. The first one is dedicated for compiling bare-metal programs, and the second one can also be used to compile the application programs.
b. Decompress the file into a path on local disk, for example, to “/opt/”. Export a variable named “AARCH64_GCC_CROSS_COMPILE” to point to the tool as follows:

# if “gcc-arm-8.3-2019.03-x86_64-aarch64-elf.tar.xz” is used sudo tar -xvJf gcc-arm-8.3-2019.03-x86_64-aarch64-elf.tar.xz -C /opt
export AARCH64_GCC_CROSS_COMPILE=/opt/gcc-arm-8.3-2019.03-x86_64-aarch64-elf/bin/aarch64-elf-
# if “gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz” is used sudo tar -xvJf gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz -C /opt export AARCH64_GCC_CROSS_COMPILE=/opt/gcc-arm-8.3-2019.03-x86_64-aarch64-linuxgnu/bin/aarch64-linux-gnu

3) Decompress the IBR215 source file (example ibr215-bsp.tar.bz2) into “/home/” folder.
4.1.2 Building release
4.1.2.1 for yocto/Ubuntu/debian

cd /home/bsp-folder
./build-bsp-5.4.sh

4.1.3.2 for android
cd /home/bsp-folder
source build/envsetup.sh
lunch evk_8mp-userdebug
make ANDROID_COMPILE_WITH_JACK=false
./imx-make.sh –j4
Make –j4

4.1.3 Installing release to board

Appendix

This section provides the information of reference code.

A. How to Use GPIO in Linux

# GPIO Value Rule : gpioX_N >> 32*(X-1)+N
# Take gpio5_18 as example, export value should be 32*(5-1)+18=146
# GPIO example 1: Output
echo 32 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio146/direction
echo 0 > /sys/class/gpio/gpio146/value
echo 1 > /sys/class/gpio/gpio146/value
# GPIO example 2: Input
echo 32 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio146/direction
cat /sys/class/gpio/gpio146/value

B. How to Use Watchdog in Linux

// create fd
int fd;
//open watchdog device
fd = open(“/dev/watchdog”, O_WRONLY);
//get watchdog support
ioctl(fd, WDIOC_GETSUPPORT, &ident);
//get watchdog status
ioctl(fd, WDIOC_GETSTATUS, &status);
//get watchdog timeout
ioctl(fd, WDIOC_GETTIMEOUT, &timeout_val);
//set watchdog timeout
ioctl(fd, WDIOC_SETTIMEOUT, &timeout_val);
//feed dog
ioctl(fd, WDIOC_KEEPALIVE, &dummy);

C. eMMC Test
Note: This operation may damage the data stored in eMMC flash. Before starting the test, make sure there is no critical data in the eMMC flash being used.

Read, write, and check

#create data file
dd if=/dev/urandom of=/tmp/data1 bs=1024k count=10
#write data to emmc
dd if=/tmp/data1 of=$MOUNT_POINT_STR/data2 bs=1024k count=10
#read data2, and compare with data1
cmp $MOUNT_POINT_STR/data2 /tmp/data1

D. USB (flash disk) Test
Insert the USB flash disk. Then make sure it is in IBR210 device list.
Note: This operation may damage the data stored in the USB flash disk. Before starting the test, make sure there is no critical data in the eMMC flash being used.

Read, write, and check
USB_DIR=”/run/media/mmcblk1p1″
#create data file
dd if=/dev/urandom of=/var/data1 bs=1024k count=100
#write data to usb flash disk
dd if=/var/data1 of=$USB_DIR/data2 bs=1024k count=100
