'''连接设备'''
 
 
 
*1.确保设备连接好电源适配器并处于通电状态。
 
 
 
*2.用 Micro USB OTG 线连接好设备和主机。
 
 
 
*3.按住设备上的 RECOVERY (恢复)键并保持。
 
 
 
*4.短按一下 RRESET(复位)键。
 
 
 
*5.大约两秒钟后,松开 RECOVERY 键。
 
  
*6.注意:如果发现按了 RESET 键后还是没有发现设备,请在保持 RECOVERY 键按下的同时,长按一下 PWRKEY 键,然后才松开 RECOVERY 键。

下载[https://github.com/delongqilinksprite/pcDuino9-user-manual.git AndroidTool],解压,运行里面的AndroidTool.exe(注意,如果是Windows7/8,需要按鼠标右键,选择以管理员身份运行),如下图:
+
=== 2.Write the system to eMMC on Linux ===
  
[[File:pcduino 9 i.png|640px]]
+
RK provides a command line tool of '''upgrade_tool''' under Linux, supporting for unified firmware '''update.img''' and partition image programming.
  
'''烧写统一固件 xxxx.img 的步骤如下''':
+
There are two options for the open source tool:
 
 
*1.切换至"升级固件"页。
 
 
 
*2.按"固件"按钮,打开要升级的固件文件。升级工具会显示详细的固件信息。
 
 
 
*3.按"升级"按钮开始升级。
 
 
 
*如果升级失败,可以尝试先按"擦除Flash"按钮来擦除 Flash,然后再升级。
 
 
 
'''注意:如果你烧写的固件laoder版本与原来的机器的不一致,请在升级固件前先执行"擦除Flash"。'''
 
 
 
[[File:pcduino 9 j.png|640px]]
 
 
 
'''烧写分区映像'''
 
 
 
烧写分区映像时,请使用对应SDK下的FFTools/AndroidTool.rar烧写。步骤如下:
 
 
 
*1.切换至"下载镜像"页。
 
 
 
*2.勾选需要烧录的分区,可以多选。
 
 
 
*3.确保映像文件的路径正确,需要的话,点路径右边的空白表格单元格来重新选择。
 
 
 
*4.点击"执行"按钮开始升级,升级结束后设备会自动重启。
 
 
 
[[File:pcduino 9 k.png|640px]]
 
 
 
=== 2.在Linux烧写系统到eMMC ===
 
 
 
RK 提供了一个 Linux 下的命令行工具 upgrade_tool,支持统一固件 update.img 和分区镜像的烧写。
 
 
 
开源工具则有两个选择:
 
  
 
*rkflashtool [https://github.com/Galland/rkflashtool_rk3066 https://github.com/Galland/rkflashtool_rk3066]
 
*rkflashtool [https://github.com/Galland/rkflashtool_rk3066 https://github.com/Galland/rkflashtool_rk3066]
Line 141: Line 94:
 
*rkflashkit [https://github.com/linuxerwang/rkflashkit https://github.com/linuxerwang/rkflashkit]
 
*rkflashkit [https://github.com/linuxerwang/rkflashkit https://github.com/linuxerwang/rkflashkit]
  
它们都仅支持分区映像烧写,不支持统一固件。rkflashtool 是命令行工具,rkflashkit 有图形界面,后加了命令行支持,更是好用。以下仅对 rkflashkit 做介绍。 Linux 下无须安装设备驱动,参照 Windows 章节连接设备则可。
+
They only support the partition image programming, does not support a unified firmware. Rkflashtool is a command line tool, rkflashkit has a graphical interface and a command line support, which make it easier to use. The following only do an introduction of rkflashkit. There is no need to install the device driver for Linux, you can refer to the Windows chapter to connect the device.

如果因 flash 问题导致升级时出错,可以尝试低级格式化、擦除 nand flash:
+
If flash problems lead to an error during the upgrade, you can try low-level format or erase nand flash:
  
  sudo upgrade_tool lf  # 低级格式化

Quick Start

1.Write the system to eMMC by SD card

Download the image which named pcDuino9-SD-to-eMMC-xxx.img,use dd or Win32Disk,copy the image to SD card ,put the SD card on pcDuino9,and then pcDuino9 system on switch SD,that means switch the button “on” ,use ttl uart to watch system log,when kernel start,put the system on switch to “off”,then wait for all things done. System user name : linaro ,password:linaro

2.Write the system to eMMC on Linux

RK provides a command line tool of upgrade_tool under Linux, supporting for unified firmware update.img and partition image programming.

There are two options for the open source tool:

They only support the partition image programming, does not support a unified firmware. Rkflashtool is a command line tool, rkflashkit has a graphical interface and a command line support, which make it easier to use. The following only do an introduction of rkflashkit. There is no need to install the device driver for Linux, you can refer to the Windows chapter to connect the device.

upgrade_tool

Download Linux_Upgrade_Tool, and install to the system as the following method to be easy to call:

tar xf Linux_UpgradeTool_v1.2.tar.gz
cd Linux_UpgradeTool_v1.2
sudo mv upgrade_tool /usr/local/bin
sudo chown root:root /usr/local/bin/upgrade_tool

Write unite firmware uxxxx.img:

sudo upgrade_tool uf update.img

Program partition image:

sudo upgrade_tool di -b /path/to/boot.img
sudo upgrade_tool di -k /path/to/kernel.img
sudo upgrade_tool di -s /path/to/system.img
sudo upgrade_tool di -r /path/to/recovery.img
sudo upgrade_tool di -m /path/to/misc.img
sudo upgrade_tool di resource /path/to/resource.img
sudo upgrade_tool di -p paramater   #Write parameter
sudo upgrade_tool ul bootloader.bin #Write bootloader


If flash problems lead to an error during the upgrade, you can try low-level format or erase nand flash:

sudo upgrade_tool lf   # low-level format
sudo upgrade_tool ef   # erase nand flash

rkflashkit

Installation:

sudo apt-get install build-essential fakeroot 
git clone https://github.com/linuxerwang/rkflashkit
cd rkflashkit
./waf debian
sudo apt-get install python-gtk2
sudo dpkg -i rkflashkit_0.1.2_all.deb

erase  @<PARTITION>               Erase partition
reboot                            Reboot device
For example, flash device with boot.img and kernel.img, then reboot:
sudo rkflashkit flash @boot boot.img @kernel.img kernel.img reboot

3.SD card boot system

  • Download the xxxx.img system image
  • Prepare a memory card (C10 of more than 4GB)
  • Use the dd command to copy the system to SD
  • Insert the card into the pcDuino9, press the MASKROM button starting from the TF card to boot.

4.pcDuino9 hardware operation

Hardware operation is based on NightWiring, which is a hardware interface controlled by a cross-platform C ++ library, including UART, I2C, SPI and GPIO.Most of the code can be downloaded from wiringpi. GPIO is based on the function of the sysfs, it will be slightly slower, but very flexible.

chen@chen-HP-ProDesk-680-G1-TWR:~/work/linaro-alip/ramdisk/update$ sudo gdisk /dev/sdb
GPT fdisk (gdisk) version 0.8.8
Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present



Found valid GPT with protective MBR; using GPT.



Command (? for help): o
This option deletes all partitions and creates a new protective MBR.
Proceed? (Y/N): y

Command (? for help): n
Partition number (1-128, default 1): 1
First sector (34-126613470, default = 2048) or {+-}size{KMGTP}: 8192
Last sector (8192-126613470, default = 126613470) or {+-}size{KMGTP}: 
Current type is 'Linux filesystem'
Hex code or GUID (L to show codes, Enter = 8300): 
Changed type of partition to 'Linux filesystem'

Command (? for help): w
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/sdc.
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot.
The operation has completed successfully.

cp ../rk-initrd-build/initrd.img /media/ls/9F35-9565/
  • Add extlinux/extlinux.conf in the dev/sdb1/directory
label kernel-4.4
    kernel /zImage
    fdt /rk3288-fennec.dtb
    initrd /initrd.img
    append  earlyprintk console=ttyS2,115200n8 rw root=/dev/ram0 rootfstype=ext4 init=/sbin/init ramdisk_size=49152
  • Copy u-boot-dtb.img, uboot-spl.img, boot.img, rootfs.img and update.sh to /dev/sdb1
mkdir /media/chen/9F35-9565/update

Update the pcDuino9 system via SD card

Insert the SD card into the pcDuino9, and set the switch to the startup mode. When the kernel is up, set the switch to start the eMMC. When the system is up, you can see that the system image is being programmed into eMMC.
