  • Forum Post: Re: Which JTAG should I use for working with Stellaris Ethernet-Enabled Intelligent Display Module Reference Design Kit (RDK) (PoE version)

    Matthew Kendall
    None of these low-cost devices are really emulators, of course. In the traditional sense an emulator is something that you plug in to your target board *instead* of the target processor; it emulates all the functions of the processor and also provides debugging facilities. Typically real emulators are...

    Birgir Thoroddsen
    Hi everyone, This issue might have been raised here, I am not exactly sure.But here it is anyway. The problem is basically that when I raise the clock frequency of the processor to something like 20MHz and above, my JTAG debugger interface looses contact with my processor. I am doing this with...

    Hello, I bought the Stellaris BLDC RDK with the BL3056 motor. However, when I was updating the firmware board I clicked in the StellarisWare\boards\rdk-bldc\basic-bldc\ccs\Debug\basic-bldc.bin. I cannot access the board anymore via Ethernet or JTAG, and I cannot send other firmware either. ...

  • Forum Post: JTAG question for LM3S6911

    Al B
    I see that by default all JTAG pins will have an internal pull-up resistor. However, it seems that for normal part operation I’d want TRST# to be active (low), to keep the TAP controller and other JTAG circuitry in reset. Is this true? If so, should I change the TRST# resistor setting...

  • Forum Post: Trouble disabling JTAG on LM3S6965

    Chris Curry
    I'm developing a system based around the LM3s6965 that requires the use of nearly every GPIO available. Port C is to be used as an 8-bit bus, but PC[0:3] is concurrently used for JTAG. I implemented a way to enable or disable the JTAG pins through ethernet communication. To do that I used this code...

    Let us all know if you figured out anything on this, I am having the same problem. I know that you will likely have to change the .cfg files, but I tried that and it didn't work yet for me. I think there may also be a conflict between the ftdi drivers provided with the eval kit and the version of...

    We tested revision C3 LM3S9B90 to see if it can fix our JTAG locked-up problem which troubled us too many times on C1 version.

    Amy Garcia to debug code using IAR, I must (sic?) have a JLink. Is that true? Don't IAR support any other form of JTAG interface? Don't IAR support the built-in JTAG interface on Stellaris kits? Or using a Stellaris kit as a JTAG interface?
