RT5350F-OLinuXino

RT5350F-OLinuXino official images build instructions

Quick-start

1. Connect USB<->serial cable between the UART0 pins of the board and your personal computer.

2. Open your favourite serial terminal software on the COM port, created by your USB<->serial cable.

3. Set the baud rate for the connection to 57600.

4. Power on RT5350F-OLinuXino-EVB.

Prebuilt files and system restore

RT5350F-OLinuXino comes with an image loaded into the SPI flash memory. If something goes wrong you can restore the original image.

The original files can be found at this FTP location:

https://ftp.olimex.com/Ralink/RT5350F-OLinuXino/1.latest_images/

The repository contains six (7) files, two (2) upgrade binaries for each variant of Olimex-made RT5350 boards; and a text file with a link to u-boot+factory binary that serves as a restore point should a serious problem with u-boot or bootloader appears. The upgrade can be performed over different mediums, but the restore requires a programmer.

We have three variants of RT5350F-OLinuXino - RT5350F-OLinuXino, RT5350F-OLinuXino-EVB, and RT5350F-OLinuXino-EVB+ (which is the latest revisions of RT5350F-OLinuXino-EVB, starting revision C, with SD card and reset button, among other difference).

One of the two binary files for each board is meant for u-boot upgrade, while the other is meant for LuCI (web browser interface) upgrade. Read about the upgrade procedures the OpenWRT upgrading here:

    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 prebuilt OpenWRT using uboot

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.

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 prebuilt images using programmer tool

We will use ARM-USB-OCD. It has FT2232 chip which can be used to in SPI master mode. You can also use ARM-USB-TINY; ARM-USB-TINY-H; ARM-USB-OCD-H or any FT2232-based debugger.

Connect ARM-USB-OCD with RT5350F-OLinuXino-EVB according the schematic below (for the blue wire GND you can also use other GND pins available at the board; the GND is common):

RST_RT jumper MUST be closed. Then power the board to become ready writing.

Download flashrom software and build it using instructions on the site.

To program the SPI flash run:

flashrom -p ft2232_spi:type=arm-usb-ocd -w file.bin

Then wait some minutes for process to complete.

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>>==================

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.
