Hi Experts,
I am trying to use the J7 EVM platform as a gadget serial hoping that the board would allow this on the USB Type-C connector (J5). I am using the prebuilt images.
root@j7-evm:~# modprobe g_serial [ 36.011536] udc-core: couldn't find an available UDC - added [g_serial] to list of pending drivers root@j7-evm:~# root@j7-evm:~# zcat /proc/config.gz | grep DUAL CONFIG_USB_MUSB_DUAL_ROLE=y CONFIG_USB_DWC3_DUAL_ROLE=y CONFIG_USB_ISP1760_DUAL_ROLE=y root@j7-evm:~# root@j7-evm:~# zcat /proc/config.gz | grep GADGET CONFIG_USB_CDNS3_GADGET=y # CONFIG_USB_MUSB_GADGET is not set # CONFIG_USB_DWC3_GADGET is not set # CONFIG_USB_ISP1760_GADGET_ROLE is not set CONFIG_USB_GADGET=m # CONFIG_USB_GADGET_DEBUG is not set # CONFIG_USB_GADGET_DEBUG_FILES is not set # CONFIG_USB_GADGET_DEBUG_FS is not set CONFIG_USB_GADGET_VBUS_DRAW=2 CONFIG_USB_GADGET_STORAGE_NUM_BUFFERS=32 # CONFIG_USB_GADGET_XILINX is not set # CONFIG_GADGET_UAC1 is not set CONFIG_USB_GADGETFS=m CONFIG_USB_MIDI_GADGET=m root@j7-evm:~# root@j7-evm:~# cat /proc/device-tree/interconnect@100000/cdns_usb@4104000/usb@6000000/dr_mode otg
Any help would be appreciated.
