[Driver Request] LPC Open 2.02 - Composite Driver CDC and DFU

[lpcware]

Hello,

I'm trying to build a project on the LPC 4330 using the new USB Rom examples from LPC Open 2.02. I wanted to use the USBD Rom DFU Composite Project as a basis for my project, however after building and debugging my PC only detects the Mass Storage device and the HID.

I downloaded the Driver Package for the examples that are posted next to the download link for the LPC Open 2.02 however Windows 7 doesn't want to detect a Valid Driver for the DFU and CDC.

On a side note when running the standart USBD CDC Vcom Project the drivers get installed without a problem and I can establish a Vcom connection and mess around with the terminal.

Any Ideas on where to get the missing drivers?

Many thanks,

~m.yzb

Thanks for the reminder. The LPCOpen Windows driver package has been updated to include drivers for this example.


Please get the latest windows drivers  package.

Note, the DFU interface in this example will in AppIdle state in normal mode. So DFU_DETACH command should be sent to put the device in DfuIdel state. So if you are using open source dfu-util tool (also available in LPCXpresson installs bin director), you need to issue the command in following order. Make a note of "-e" option first time. The test.bin file use below is generated based on lpcopen\applications\lpc18xx_43xx\keil_uvision_projects\hitex_eva_4350\periph\periph_iram_blinky example project.
