FAQ

  • Can I use ARM-USB-TINY with EW-ARM?
  • IAR EW has support for GDB and works with ARM-USB-TINY.
  • I am currently using operating system X. It has FTDI drivers, how should I alter them to work with my installation?
  • FTDI provide drivers and instructions at their web site, download them and use our ARM-USB-TINY PID: 0x0004, VID: 0x15BA to install the drivers.
  • I have LPC1227 board and can't program it with your OpenOCD debugger. What do I do wrong?
  • LPC1227 lacks JTAG according to the microcontroller's datasheet. The board can be programmed only via SWD (Serial Wire Debug) interface. Olimex OpenOCD debuggers have JTAG by default. You would need an addiitonal adapter – ARM-JTAG-SWD.
  • How to install ARM-USB-TINY to work with CrossWorks:
  • Test with the FTDI drivers. The FTDI drivers can be downloaded from the following address: 
    https://www.olimex.com/Products/ARM/JTAG/_resources/OLIMEX-FTDI-drivers-2-12-04.zip

    There is profile for ARM-USB-TINY in CrossWorks, but if you want to use "Generic FTD2232" target interface you have to do as follows:

    1. Right click on a blank space in the targets window and select "New Target Interface > Generic FT2232 Device".
    2. Right click on the new target interface and select "Properties" - set the following properties:
      Connected LED Inversion Mask 0x0000
      Connected LED Mask = 0x0800
      nSRST Inversion Mask = 0x0200
      nSRST Mask = 0x0200
      nTRST Inversion Mask = 0x0000
      nTRST Mask = 0x0100
      Output Pins = 0x0F1B
      Output Value = 0x0D08
      Running LED Inversion Mask = 0x0000
      Running LED Mask = 0x0800

    PID: 0x0004
    VID: 0x15ba

    In CrossWorks 1.7 there are Target interfaces for Olimex JTAGs, note that RTCK is not used with a FT2232 design so your JTAG clock should not exceed 1/6 of your target MCU clock or the JTAG will lock up. Start with JTAG divider 10 and decrease until you are able to debug to find your own value for your target.

  • What is the difference between ARM-USB-OCD and ARM-USB-TINY?
  • ARM-USB-TINY is stripped down version of ARM-USB-OCD, the differences are: no output buffers just current limitation resistor protectors, no RS232, no additional power supply for the target.
  • Can I debug high voltage targets with ARM-USB-TINY?
  • ARM-USB-TINY is not isolated, but you can use USB-ISO or USB-ISO-HS isolator device to protect your PC while debugging high voltage targets.
  • Howdy, guys. I can't program my MSP430 and PIC16 boards with your robust debugger. I need help ASAP.
  • Technically, it is possible to program targets different than ARM using our OpenOCD debugger. Practically, almost all users use the debugger for ARM programming and only ARM targets are officially supported. There is a reason that the prefix in the name of the debugger is 'ARM-'.
  • I am the maintainer of a commercial IDE with custom debugger code. I want to include support for your OpenOCD tools in my software, however I can't find specific information. It is obviously a win-win situation for both parties. Is it possible to provide me with more specific technical information for your debuggers?
  • Olimex can provide the necessary information and cooperate with interested parties if they want to add low-cost USB debugger support to their C compilers and IDEs.
