TDA4VM: DFU download sysfw.itb failed

Part Number: TDA4VM

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!
