LPC55S69 - Why am I not seeing a new USB device for the composite SD card USB demo example for IAR and FreeRTOS.

Hi,

I am trying to run the usb_device_composite_cdc_msc_sdcard USB example for IAR with freeRTOS and when i load the project and attach the USB cable to the LPC55S69 board, I am not seeing any new devices in the device Manager. When I tried the virtual Com port example it worked fine, so I think I am doing everything correctly. I am running on Windows 10.

Thanks,

Don

Hello,

Did you try following the readme steps?

Maybe the issue is regarding a driver signature from the OS, please follow the steps from page 9.

Please let me know if this helps,

Regards
