Stm32mp157c-odyssey OTG issues

[softcity002]

Hello, 
I am using and stm32mp157c-odyssey SoM with a custom made motherboard, 
However I am having issues getting the usb port function properly.I am using otg fs. It fails the enumeration in the pc side and gets stuck at L1 sometimes and other errors. I still don't know if it's a hardware or software related issues. I am configuring it as device only. 
below I will include picture of the usb schematic, the logs, as well as the device tree node.
 Note : We are not using otg_fs_id it's not connected to anythhing , and vbus comes directly from the PC host to the OTG_vbus pin so no vbus gpio.
Using yocto image 6.1 mickledore.

&usbotg_hs {
compatible = "st,stm32mp15-fsotg", "snps,dwc2";
status = "okay";

pinctrl-names = "default";
pinctrl-0 = <&usbotg_fs_dp_dm_pins_a>;
dr_mode = "peripheral";

};

Hi @softcity002 

It seems control transfers on EP0 are failing. Disable LPM as a test.

This could be SW or hardware issue. You can reach to Seeed SoM directly to get support.

Hi, 

did you try to use similar settings than the high-speed without VBUS nor ID ?
DT configuration example as high-speed OTG in Host or Peripheral mode, with micro-B or Type-C connector, and with VBUS and ID left unconnected

	dr_mode = "peripheral"; 
	usb-role-switch; 
	role-switch-default-mode = "peripheral"; 

Regards.

Hello, I did disable LPM but the behavior didn't change.

Hi.

I did try that and everything proposed in the ST wiki, but same behavior.
