OpenOCD under Ubuntu 10.10 with a OpenJTAG

Development Boards MicroMod
1

Hi Everyone.

OK I know that this list should be for those that have purchased JTAGs from SparkFun (which I have done in the past) but I am stuck with a issue I have spent several days on and I can’t see the tree’s from the forest any more so; I need some outside guidance please.

Host Setup:

64bit AMD system + Ubuntu 10.10 + latest upgrades. Running Open On-Chip Debugger 0.4.0 (2010-10-08-15:44) and

GNU gdb (GDB) 7.2-ubuntu on Linux 2.6.35-25-generic #44-Ubuntu SMP.

Target Setup:

Mini2440 with 64MB ram. I have been able to install U-Boot by using supervivi so that I can test and download Kernel & Qt4 applications under development.

JTAG Tool:

OpenJTAG v3.1 from http://www.100ask.net. JTAG connectivity plus a secondary serial line that normally connects to the Target primary SIO. In this case it is connected to the Target DB9 serial terminal line.

Running OpenOCD with the following command string:

**openocd -f $TLOC/board/mini2440.cfg -f $TLOC/interface/neodb.cfg -f $TLOC/target/samsung.S3C2440.cfg --command init**

where exported $TLOC=/usr/share/openocd/scripts/.

On running the above command I get the following screen output.

    • So indications are that I have Two Problems. A> The NAND Flash Controller Type and B> The JTAG Interface undefined

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

    A> The NAND Flash Controller Type Problem: Firstly, I don’t know how to address the NAND Flash Controller Type, and I would be most apprciative if anyone can give assistance here. It doesn’t appear that there is any NAND controller onboard, rather the NAND is handled by the S3c2440 itself. This could be incorrect though.

    B> The JTAG Interface undefined: Now the JTAG interface was supposedly set accordingly to the script $TLOC/neodb.cfg containing the following:

  • #

    Openmoko USB JTAG/RS232 adapter

    interface ft2232

    • The /dev/ttyUSB0 is connecting to the serial device as I can see if I download a mass of text the applicable LED flashes.

    i.e.: dmesg >/dev/ttyUSB0

    If anyone with OpenOCD with Mini2440 ARM system experience could kindly assist please.

    Thanks.

    Hi all.

    You can now disregard the former post using the OpenJTAG device. I was wasting too much time so I purchased two Olimex ARM JTAG devices from Sparkfun.

    Hopefully now all my issues will be over.

    Cheers. :smiley:
