The chip was downloaded successfully once, and then the chip download fails, the reset pin appears low-level all the time！

Hi,

Check if reset is right after Power on Reset low.

If yes then you have brick device by programming ECC error into HSM flash block.

I recommend you to not program HSM flash block at all.

We have already many threads on this here on community.
