RT5350F-OLinuXino

Overview

Prebuild images

RT5350F-OLinuXino comes with image loaded into the SPI flash memory. If something go wrong you can restore the original image. See #Upload image using uboot or #Upload image using programmer.

The images are:

  • bootloader.img
  • openwrt.bin

These two can be uploaded using uboot.

  • uboot+factory.bin
  • uboot+factory+openwrt.bin

These two - with flashrom.

Building uboot

Get the sources from:

 git clone https://github.com/OLIMEX/u-boot_RT5350F-OLinuXino
 cd u-boot_RT5350F-OLinuXino

Target must be build with gcc3.4! This is very important because with another versions of GCC the build process will fail. You can find that version from Ralink SDK. Use Google to find it.

Run

 make menuconfig

You'll see that the default location is /opt/buildroot-gcc342/bin. Change that with your path.

To actually build u-boot run:

 make

At the end of the process you'll see something like this

 ===============<<IMPORTANT>>==================
 Notes:Uboot firmware in flash is uboot.img NOT uboot.bin
 ================================================
 
 ./tools/mkimage -A mips -T standalone -C none \
         -a 0x80200000 -e 0x80200000 \
         -n "SPI Flash Image" \
         -r SDR -s 16 -t 32 -u 16 \
         -y 0x0 -z 0x0 -w 0xFF -d uboot.bin uboot.img
 Image Name:   SPI Flash Image
 Created:      Thu May 14 08:23:19 2015
 Image Type:   MIPS Linux Standalone Program (uncompressed)
 Data Size:    106912 Bytes = 104.41 kB = 0.10 MB
 Load Address: 0x80200000
 Entry Point:  0x80200000
 DRAM Parameter: 6 (Parm0=0 Parm1=0)

The image uboot.img can be uploaded via tftp.

Building OpenWRT

Make a directory:

 # mkdir some_dir
 # cd some_dir

Download sources:

 # git clone https://github.com/OLIMEX/openwrt -b rt5350f

Go into openwrt directory:

 # cd openwrt

You can use our config:

# make

or if you want to change something:

# make menuconfig
# make

After some time build will finish. The image is found under:

 build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_rt305x/\
 openwrt-ramips-rt305x-olinuxino-rt5350f-squashfs-sysupgrade.bin

Place that file on some tftp server and then upload it to the board.

Upload image using uboot

Reboot the board and you'll see:

 Please choose the operation: 
    1: Load system code to SDRAM via TFTP. 
    2: Load system code then write to Flash via TFTP. 
    3: Boot system code via Flash (default).
    4: Entr boot command line interface.
    7: Load Boot Loader code then write to Flash via Serial. 
    9: Load Boot Loader code then write to Flash via TFTP.

Upload OpenWRT

Press 2, then y and enter some values for ip, server ip and filename:

 You choosed 2
 
  
 2: System Load Linux Kernel then write to Flash via TFTP. 
  Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N)
  Please Input new ones /or Ctrl-C to discard
         Input device IP (10.10.10.123) ==:10.10.10.123
         Input server IP (10.10.10.3) ==:10.10.10.3
         Input Linux Kernel filename () ==:file.bin

Then your new system will boot.

Upload new uboot

Press 9, then again enter ip address, server ip and filename to upload:

 You choosed 9
 
  0 
 raspi_read: from:40028 len:6 
 .
    
 9: System Load Boot Loader then write to Flash via TFTP. 
  Warning!! Erase Boot Loader in Flash then burn new one. Are you sure?(Y/N)  

Press Y and continue:

 Input device IP (10.10.10.123) ==:10.10.10.123

Enter some static address for the device, for example 192.168.0.201.

Next enter server address, for example 192.168.0.15:

 Input server IP (10.10.10.3) ==:192.168.0.15

Finally enter filename:

 Input Uboot filename () ==:bootloader.img


Don't forget to plug LAN cable. You should see something like that:

Upload image using programmer

We will use ARM-USB-OCD. It has FT2232 chip which can be used to in SPI master mode.

Connection


Connect ARM-USB-OCD with RT5350F-EVB according the simple schematic. RST_RT jumper MUST be closed. Then power the board to become ready writing.
