Qi - Using Arduino or Linino Firmware

Using Arduino Yun Firmware

===========================

You can use the original Arduino Yun firmware or use Linino Yun firmware. Be sure to flash the Serial hex to your AVR first.

Domino Qi uboot can support Arduino and Linino firmware, so you don't risk bricking your device when you try. But please do this carefully and make sure every step works succefully.

The original Arduino Yun firmware is here: https://www.arduino.cc/en/Main/Software#toc8

The original Linino Yun firmware is here: http://download.linino.org/linino_distro/lininoIO/latest/

Using Arduino Yun Firmware

Method 1: Doing this in uboot console

Connect to the serial according to these steps.

Press the "Reset" button to reset the OpenWrt system. Then quickly type gl to enter the uboot console.

Change env: setenv bootcmd bootm 0x9fea0000

setenv bootcmd bootm 0x9fea0000
saveenv

Setup your tftp server and download the kernel, rootfs to your Domino Qi.

Kernel

tftp 0x80060000 openwrt-ar71xx-generic-yun-16M-kernel.bin;
erase 0x9fea0000 +0x140000;
cp.b $fileaddr 0x9fea0000 $filesize;

rootfs

tftp 0x80060000 openwrt-ar71xx-generic-yun-16M-rootfs-squashfs.bin;
erase 0x9f050000 +0xE50000;
cp.b $fileaddr 0x9f050000 $filesize;

Now type reset to reset your board and you will have the original Yun firmware running.

Method 2: Doing this in Domino Qi system

After you boot your Domino Qi system, ssh to your system.

check if you can access the environment variables using fw_printenv.

If you get the following error message, you have use uboot console to flash the firmware.

root@domino:/# fw_printenv 
Warning: Bad CRC, using default environment
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootm
bootdelay=5
baudrate=115200

Don't continue if you get the above message.

If you don't have a Bad CRC message, continue with the following:

fw_setenv bootcmd "bootm 0x9fea0000"
sysupgrade -v -n --force /mnt/sda1/openwrt-ar71xx-generic-yun-16M-squashfs-sysupgrade.bin

If you have a Bad CRC message, don't do this, as this will cause your board not bootable.

Using Linino Firmware

You can also use the Linino firmware for Arduino Yun. Linino has two branch, one is master, one is LininoIO.

For master branch, download from http://download.linino.org/linino_distro/master/latest/, the file names are:

  • openwrt-ar71xx-generic-linino-yun-16M-250k-kernel.bin
  • openwrt-ar71xx-generic-linino-yun-16M-250k-rootfs-squashfs.bin
  • openwrt-ar71xx-generic-linino-yun-16M-250k-squashfs-sysupgrade.bin

For LininoIO branch, download from http://download.linino.org/linino_distro/lininoIO/latest/, the file names are:

  • lininoIO-generic-linino-yun-kernel.bin
  • lininoIO-generic-linino-yun-rootfs-squashfs.bin
  • lininoIO-generic-linino-yun-squashfs-sysupgrade.bin

Method 1: Doing this in uboot console

Connect to the serial according to these steps.

Press the "Reset" button to reset the OpenWrt system. Then quickly type gl to enter the uboot console.

Change env:

setenv bootcmd bootm 0x9fea0000
setenv bootargs console=ttyATH0,250000 board=linino-yun mem=64M rootfstype=squashfs,jffs2 noinitrd mtdparts=spi0.0:256k(u-boot)ro,64k(u-boot-env)ro,14656k(rootfs),1280k(kernel),64k(nvram),64k(art),15936k@0x50000(firmware)
saveenv

Setup your tftp server and download the kernel, rootfs to your Domino Qi.

For Linino firmware

Kernel

tftp 0x80060000 openwrt-ar71xx-generic-linino-yun-16M-250k-kernel.bin;
erase 0x9fea0000 +0x140000;
cp.b $fileaddr 0x9fea0000 $filesize;

rootfs

tftp 0x80060000 openwrt-ar71xx-generic-linino-yun-16M-250k-rootfs-squashfs.bin;
erase 0x9f050000 +0xE50000;
cp.b $fileaddr 0x9f050000 $filesize;

For LininoIO firmware

Kernel

tftp 0x80060000 lininoIO-generic-linino-yun-kernel.bin;
erase 0x9fea0000 +0x140000;
cp.b $fileaddr 0x9fea0000 $filesize;

rootfs

tftp 0x80060000 lininoIO-generic-linino-yun-rootfs-squashfs.bin;
erase 0x9f050000 +0xE50000;
cp.b $fileaddr 0x9f050000 $filesize;

Finally use reset to reset your board and boot the firmware.

Method 2: Doing this in Domino Qi system

If you have already boot the Domino Qi system, check if you can access the environment variables using fw_printenv.

If you get the following error message, you have to use uboot console to flash the firmware.

root@domino:/# fw_printenv 
Warning: Bad CRC, using default environment
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootm
bootdelay=5
baudrate=115200

If you do NOT have a Bad CRC message, continue with the following. Otherwise use method 1.

fw_setenv bootcmd "bootm 0x9fea0000"
fw_setenv bootargs "console=ttyATH0,250000 board=linino-yun mem=64M rootfstype=squashfs,jffs2 noinitrd mtdparts=spi0.0:256k(u-boot)ro,64k(u-boot-env)ro,14656k(rootfs),1280k(kernel),64k(nvram),64k(art),15936k@0x50000(firmware)"

To upgrade to Linino firmware:

cd /tmp
wget http://download.linino.org/linino_distro/master/latest/openwrt-ar71xx-generic-linino-yun-16M-250k-squashfs-sysupgrade.bin
sysupgrade -v -n --force openwrt-ar71xx-generic-linino-yun-16M-250k-squashfs-sysupgrade.bin

To upgrade to LininoIO firmware:

cd /tmp
wget http://download.linino.org/linino_distro/lininoIO/latest/lininoIO-generic-linino-yun-squashfs-sysupgrade.bin
sysupgrade -v -n --force lininoIO-generic-linino-yun-squashfs-sysupgrade.bin

Wait until the process finish and reset your board.
