CCS/BQ20Z95: Which command can enter ROM mode?

Hello
1. I enter the ROM mode and import the SENC file and then restart the bq Evaluation Software. I can't connect to the bq Evaluation Software.
2, I entered the ROM mode to export the SENC file, and then sent the 0x08 command, the board is also not connected to the bq Evaluation Software.
Thank you!

Hello, after entering the bq Evaluation Software manually, there is some data, and the program can also load the SENC file.

Hello, can't program now, it should be without exiting ROM mode.
Already sent the 08 command in pro, or not.
But short-circuit the PIN30 and PIN31 of the chip, just fine.

Hello, I did it this way, but I still can't retreat from ROM mode.

 ok, thank you very much
