Tool/software:

Hello experts,

We‘re about to flash spinor flash via the USB interface under device's U-Boot stage. After connecting device and PC, and startup DFU mode under uboot, the PC cannot detect the USB device. How to configure the dts to support usb?

Opeartions we taken is as follows:

SDK 0902

uboot :

HI Jietingdu,

Just a couple of questions to ask:

Are you using TI J721E BOARD or custom board?
Are you using the default code provided by TI or have you made any changes to it?
- If yes,can you specify the changes made.
Also I would strongly recommend going through the below FAQ to see if you are missing something:
- e2e.ti.com/.../faq-tda4vh-ospi-flashing-using-dfu-cum-dfu-issues

Thanks for answering.

board: J784S4_EVM

We have gone through this link. However, the issue is not similar to ours. Our goal is to download firmware via USB during U-Boot stage, running on spi-nor flash, instead of on DFU. The true problem is that the PC fail to detect our usb gadget device under uboot stage.

We also tested the official U-Boot image from the 0902 SDK, but encountered the same issue. Therefore, I modified the Device Tree as follow. Still, USB cannot be detected.

Update: Our board is connected to the PC via a Type-C interface, and the USB3.1 data cable has been tested to be functional.

Hi Jietingdu,

Sorry for the late reply,as I was out of office last week.

So,just to confirm,can you verify if you are able to the detect the USB in dfu boot mode when executing the 'lsusb" command from the host PC after setting the boot switch settings to DFU boot mode?

Regards

Gokul

Hi Gokul Praveen,

Yes. This issue has been resolved. After enable USB 2.0 in usb0 node of uboot dts, and running DFU in tda4vh device uboot, under sd bootmode, the host PC can already detect the device via "lsusb".
