Hi user124847,
Are you using the devkit or custom board?
Is there any serial console log output after you powered up the board?
If yes, please provide the log to me for further check.
And please help to try if it could enter force recovery mode (use lsusb on your host to confirm if your host could detect the board with 7019)
You could refer to the following instruction to enter force recovery mode.
