stellaris usb

Tirthesh,

Are you referring to DK-LM3S9D96 development kit or are you using the LM3S9B96 in your own design?

Regards,

Daniel

Daniel,

I am using the LM3S9B96 in my design directly. I am trying to implement USB interface directly to program the board, can you please help me with the initial configuration for the same. I already designed the board with the end connection required for the USB only. My hardware is not recognized by PC.

We already programmes boot_usb.bin(which is given in stellarisware/ file using LM FLASH programmer through UART.

Regards,

Tirthesh

Tirthesh,

I'm not exactly sure what you are trying to accomplish. Could you please provide some more information? Are you trying to set up a USB bootloader or are you trying to use USB as an ICDI?  Do you have the ability to program with JTAG?

Regards,

Daniel

We already programmes boot_usb.bin(which is given in stellarisware/ file using LM FLASH programmer through UART.

Then, the VID/PID of boot_usb is defined in bl_config.h

C:\StellarisWare\boards\dk-lm3s9b96\boot_usb\bl_config.h

Daniel,

basically i want to use alone USB to program my stellaris without the use of JTAG.What i did is made the required circuit and programmed the design with stellarisware/boards/dk-lm3s9b96/boot_usb/ccs/debug/boot_usb.bin using LM FLASH programmer.Now also the board is not recognised by pc.

Can u Suggest me which to USB driver should i use to make it recognised and is their any mistake in the steps i have taken for the same.please help me for the same.
