Hello Harsh

Is this is a brand new Launchpad out of the box or was it used for programming some other code?

Hello amit

not brand new but also not used for programming. i just check before but never used

Hello Harsh,

And when you checked (and not used) was it working? Secondly, can you check the position of the switch on the top left side of the board. Is it on the device or debug side. Move it to the debug side and check if the LED's come up?

Also a snapshot of the board with the switch on debug side would be useful for a visual inspection.

Amit

Hello Harsh,

Now since the the LED is glowing, can you check in the Windows Device Manager that the LaunchPad drivers show up on the PC?

hello amit,

and this image show launchpad

0 Amit Ashara over 9 years ago in reply to Harsh garg

TI__Guru**** 244400 points

Hello Harsh

Your Launchpad is fine as the COM port is showing up and so are the JTAG drivers. And from my reckoning the original application has been erased, so that is hwy blink LED is not working. You will have to reflash the same from TivaWare examples for ek-tm4c123gxl.

how can i reflash pls suggest me path

0 Amit Ashara over 9 years ago in reply to Harsh garg

TI__Guru**** 244400 points

Hello Harsh,

Download and install TivaWare from TI web site and the LMFlashProgrammer application to flash in the binary from the examples/boards/ek-tm4c123gxl/qs-rgb

The LMFlashProgrammer is pretty intuitive when it comes to flashing a binary.

0 Harsh garg over 9 years ago in reply to Amit Ashara

Intellectual 895 points

and what is this " examples/boards/ek-tm4c123gxl/qs-rgb"

0 Amit Ashara over 9 years ago in reply to Harsh garg

TI__Guru**** 244400 points

Hello Harsh

That is the path of the example code for the blinking RGB LED's in TivaWare. Have you ever worked with TM4C devices earlier, used TivaWare, etc. If not then I would suggest

Hello Harsh

Were you able to flash the binary image using the LMFlashProgrammer? I would "strongly" suggest going through the wiki link first.

0 Amit Ashara over 9 years ago in reply to Harsh garg

TI__Guru**** 244400 points

Hello Harsh,

As I suggested "wiki link first". Then use the Help on the LMFlashProgrammer to understand how to use the different options/features of the tool.

Hello sir,

now i detect the main prblm that is my laptop is not able to detect my launchpad. when i connect this then in device manager it shows USB serial device not stellaris virtual serial port

0 Amit Ashara over 9 years ago in reply to Harsh garg

TI__Guru**** 244400 points

Hello Harsh,

Uninstall and delete the USB driver, then use the stellaris_icdi_drivers to get the correct device driver for COM Port

0 Amit Ashara over 9 years ago in reply to Harsh garg

TI__Guru**** 244400 points

Hello Harsh,

I have seen reports of USB driver issue on windows 10. Why can't you follow the steps listed earlier to remove the USB driver and install new one.

0 Amit Ashara over 9 years ago in reply to Harsh garg

TI__Guru**** 244400 points

Hello Harsh,

We have seen a similar issue for Windows 10 and since it is still beta OS, we would not be able to support till we know that the platform is stable. Suggest moving to a Win7 or Win8 machine.

TI__Guru**** 244400 points

Hello Harsh,

Please run the unlocking sequence on the board before attempting to flash a new image. As I mentioned it may be highly likely that the device has been used and has a faulty code which may be preventing JTAG access
