Hi,
We received two J7200XSOMXEVM system-on-module—when paired with the J721EXCP01EVM common processor board. along with bootable SD cards.
Tried to boot the board with provided bootable SD card in which following images (under BOOT partition tiboot3.bin, tispl.bin and u-boot.img , under rootfs partition kernel dtb and rootfs files ) are present .
we could see the below USB driver related traces from dmesg log, but we don't see any traces when we attach/detach the pen drive, basically it is not detecting the USB devices.
root@j7200-evm:~# dmesg | grep -i usb
[ 7.398824] usbcore: registered new interface driver usbfs
[ 7.398869] usbcore: registered new interface driver hub
[ 7.398964] usbcore: registered new device driver usb
SDK downloaded from below URL path.
could you please check and let us know why USB devices are not supported. does related drivers are not part of SDK which is shared?
Regards
Praveen
Hi Praveen
Where are you connecting the USB device is it on the typec or on the USB hub ?
on j7200 controller is shared between typc and usb hub so only on can be active at a time.

Hi Praveen
As mentioned earlier only one can work at a time as there is only single host controller

Hi Diwakar,
Even i am trying with just connecting with usb hub, but still no detection is happening when i insert the pen drive device.
Attached the snapshot for your reference.

Hi Praveen
By default the type c port is selected you need to do the gpio hogging to change the mux value as high so that hub can be used

Hi Diwakar,
Yes , suggested patch worked perfectly to enable the type-A USB . Now both type-C and type-A USB interfaces are working as expected.
Appreciate you great support. Thanks you.!
