Technical discussions about Freescale (Motorola) DSPs (including the DSP56000, DSP56300, DSP56600, 56800 DSPs).
Hello, I have been using a 56800E USB Tap (CWH-UTP-ONCE-HX) for a while now. In the past, the TX/RX LED flashes green and I am able to program my board. Today, the TX/RX LED is flashing red and I am unable to program my board. According to the manual, a red flashing LED indicates that the tap is powered but is not configured. Does anyone know how to configure it and why I need to configure it all of a sudden? Thank you. Hardeep
Hello Hardeep, I had the experience of the USB-Tab flashing its red light and not=20=20 responding just two days ago -- it happened when plugging and=20=20 unplugging the USB cable several times (i'm not sure whether one is=20=20 supposed to remove the usb cable before plugging or unplugging the=20=20 target board?). The problem went away after rebooting the pc -- somehow the windows=20=20 usb driver must have gotten confused. Good Luck!

Robert, Thanks for the prompt response. I have already tried to reboot my PC, however that did not seem to make any difference. I have tried to reconfigure the usbtap through Command Converter Server (CCS), but when I type the command "config cc", I receive an error saying "Maximum number of Command Converters reached". When I type "show cc" it says "0: Parallel Port (SPP) (lpt:1) CC software ver. (3.3)" Thanks. Hardeep -----Original Message----- From: R.A.

Hello friends, I am using a 56F8014 and I need to do the square root of a number. I do: #include "math.h" double x=1, y=1; y = sqrt (x); And I receive the following error message: * Function have in the prototype... sqrt What i`m doing wrong? Cannot I use "math.h" to do this? Tks Danilo.
