RA6E1 or RA4E1 USB Example


i evaluate for a new project the RA[4/6]E1 Controllers.

I have some problems to find a working USB sample. Currently i have a fpb_ra6e1 board here. 

In the board examples folder https://github.com/renesas/ra-fsp-examples/tree/master/example_projects/fpb_ra6e1 is no USB sample. 

I modified the sample:



to work with the R7FA6E10F2CFP Controller. But nothing (USB) is working.

I have Connected USB-DP, USB-DM and USB_VBUS to P407. Adjusted the USB Clock to 48 MHz. 

Is a demo HID, CDC, WINUSB is available to evaluate the USB functions?

  • Hi,

    I'm having similar issues trying to get USB HID to work on an FPB-RA4E1 board. I soldered a USB cable directly to USB_DM and USB_DP and used P407 for USB_VBUS though some resistors and added and configured a 24 MHz crystal. I tried both the usb_phid_ek_ra4m2_ep and USBX_phid_ek_ra4m2_ep demo applications. Both applications run just fine, but when I connect the USB cable to my computer, the device manager reports "Unknown USB Device (Device Descriptor Request Failed".
