    v57 v58  
    177177 * fOP: '''USB Open Rev  fOP''' - failure to open the USB device via libusb - you likely have the ftdi_sio serial driver loaded - [#conflictwithftdi-siodriver see above]
    178178 * FAL: '''JTAG_ID_#00  FAL''' - failure to identify a supported JTAG TAP on the target device - likely you have not powered the target board
     179 * If the error message is fDR, this is failing DRAM. There could be a hardware issue. Be sure you are using the latest jtag_usbv4 tool from the Gateworks website.
    179180 * If while programming a board it gets stuck an invalid image may have locked up the board or the board is not powered on. Please try powering on the board. 
    180181 *  Flashing a invalid image. There are times when downloading files that the html version was downloaded rather than the file itself.  Check the file extension and file size to be sure you have the correct file.
