Tool/software: Starterware
Dear sir,
1. I had tried to flash through USB in DFU mode. but i had connected usb to custom board that is not detected means that is not show in device manager.
2. I had tried on evolution board in that time detected on first time means controller without any code. if controller have a code then after erasing the flash thenDFU is detected.
3. I am using LM flash programmer tool to flash the controller through usb dfu mode.
Please suggest
Regards,
Sateesh.
Let's make sure the PC can even detect your LaunchPad first. I first disconnect all USB ports to the LP so the LP is powered off for a few seconds. I make sure the LP was erased earlier. I connect the USB port and then connect the Debug USB port so the LP is powered. I then open up the device manager and below is what I see.
Did you see the Stellaris Device Firmware Upgrade like the below screenshot?
Please confirm that you can load your application via USB DBU mode with the LaunchPad.
If it works for LaunchPad, then what does the device manager display after you plug in your custom board.
In your second screenshot for the LaunchPad I do not see Stellaris Device Firmware Update. Please confirm if you have erased the flash first. If not, it will not recognize as DFU device.
In the LM Flash Program under the 'Other Utilities' tab there is a button for ICCI Firmware Update. Please click the Update button and try again to see if you can see 'Stellaris Device Firmware Update' in device manager.
You see see something like this in the LM Flash Programmer if the flash is erased and if you select USB DFU.
Please also make sure you have the 4.7k resistor on the RBIAS pin to ground on your custom board per the below errata.
