RT5350F-OLinuXino

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

 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. Reboot the board and you'll see:

  ##### The CPU freq = 360 MHZ #### 
  estimate memory size =32 Mbytes

 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.

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.
