Description

The gnICE is a fast and low cost USB JTAG In-Circuit-Emulator for Blackfin processors. It's designed to provide reliable JTAG debugging and CFI NOR Flash programming via USB. The gnICE JTAG Adapter Cable is an Open Source Hardware, based on the FT2232 chip from Future Technology Devices International Ltd.

gnICE description: https://docs.blackfin.uclinux.org/doku.php?id=hw:jtag:gnice

gnICE+ description (faster): https://docs.blackfin.uclinux.org/doku.php?id=hw:jtag:gnice-plus

Get a gnICE+

gnICE+ can be ordered from Bluetechnix, please see our web page.

Linux: Set proper USB permissions for gnICE/gnICE+

By default, you won't be able to communicate with the gnICE without root permissions.

To tell udev to set the proper permissions on gnICE's device files, add the file /etc/udev/rules.d/10-gnice.rules with the following content: 

SUBSYSTEMS!="usb", ACTION!="add", SUBSYSTEM!=="usb_device", GOTO="kcontrol_rules_end"
SYSFS{idProduct}=="f001", SYSFS{idVendor}=="0456", MODE="660", GROUP="plugdev"
SYSFS{idProduct}=="f000", SYSFS{idVendor}=="0456", MODE="660", GROUP="plugdev"
LABEL="kcontrol_rules_end"

Afterwards, restart udev: 

sudo /etc/init.d/udev restart

Programming flash memory with bfin-jtag from the GNU tool chain

Note #1: bfin-jtag does not support flash bank switching with GPIOs on Bluetechnix Core Modules, so on most modules, only 2MB of the flash memory will be available (but that is sufficient to program BLACKSheep or U-Boot)

Note #2: If this solution does not work for you, please read below!

Note #3: We recommend using tool chain version 2009R1.1-RC2


We use a Linux operating system and assume that bfin-jtag's path is in your ${PATH}.

Connect gnICE/gnICE+. 

bfin-jtag -q

Now, enter the following commands to flash e.g. U-Boot. 

cable gnICE
- or -
cable gnICE+

detect
initbus $BOARDTYPE
detectflash 0x20000000
flashmem 0x20000000 $BINFILE

where $BOARDTYPE depends on your Blackfin processor

  • BF518: Use bf51x
  • BF525: Use bf52x
  • BF527: Use bf52x
  • BF533: Use bf53x
  • BF537: Use bf53x
  • BF548: Use bf548_ezkit
  • BF561: Use bf561_ezkit

and $BINFILE is a binary file containing the desired flash content (e.g. u-boot.bin).

Programming flash memory with bfin-gdbproxy and Visual DSP++ Flash Tool Driver

The trunk repository of the GNU tool chain (File: e.g. blackfin-toolchain-2010R1-RC4.src.tar.bz2) contains some gdb-scripts, among them the vdsp-flash-programmer.sh script. This script uses a flash tool driver for the Visual DSP++ IDDE for flash programming.

Note #1: With this method, the whole flash size is available for programming, because the flash tool drivers are specifically implemented for our Core Modules.


  • Get the gdb scripts:
svn checkout svn://firewall-sources.blackfin.uclinux.org:80/svn/toolchain/trunk/debug-helpers/gdb-scripts gdb-scripts
  • Get the flash tool drivers:
They are available via Bluetechnix SVN portal (https://support.becom-group.com/software/); you have to register to download them.
Also see Flash tool driver files.
  • Start bfin-gdbproxy (from the GNU tool chain). It will automatically detect gnICE and gnICE+ JTAG devices and connect to the Blackfin CPU.
bfin-gdbproxy bfin --reset
  • Open a new terminal and execute vdsp-flash-programmer.sh
gdb-scripts/vdsp-flash-programmer.sh $FLASHTOOLDRIVER.dxe
  • Optional: Set pagination mode off
set pagination off
  • Use command flrestore for flash programming now, the syntax is as follows
flrestore $BIN_FILE 0 $FILE_SIZE_IN_HEX
We recommend to round up the file size to the end of the next sector (One sector is normally 128 KiB large). We observed cases where the last byte was incorrectly written if the file was given exactly.
