Good day.

As CY7C67300-100AXI hardware the upload via USB for recovery firmware oscilloscope? 

The oscilloscope is de-energized during the upgrade firmware via USB flash drive. Hangs after switching on.

Thanks in advance.

do you have a way to obtain debug logs from the EZ-Host chip? If so do they implicate that the chip has started or not? Do you have any micro level details on the issue? If you load the previous firmware again, does it work?
