Hi expert，

I try boot u-boot from USB device, that successfully complete on EVM board.

And tiboot3.bin ,sysfw.itb , u-boot.img , tispl.bin are offical release (08_00 )binary.

But on our customized board , when i download the release sysfw.itb ,it shows error.

I also try to use this patch: https://e2e.ti.com/support/processors/f/processors-forum/986479/tda4vm-with-dfu-usb-device-download-firmware-failed , but seems don't work.

Thank you for your reply!

Hi,

On your custom board can you try UART boot: https://e2e.ti.com/support/processors/f/791/t/1003471

For DFU can you let us know if there are any hardware differences with respect to USB on your custom board?

Please try out UART boot first. It will be the simplest.

hi keerthy，

I want to boot through DFU, that successful completion on EVM board.

Our customized board connected to the computer via micro-B connecter(j1700).

Now we turn off 5V VBUS supply via remove U1700 pin4.
