Oh, I thought this reset is not for the TSE core, but for the chip itself. The chip has reset_n pin. I don't have 9021GQ, but on 9021GN it's pin 56, which has to be pulled high. Check it's state with scope.

I am check reset signal on chip.

Led Link100 and RX on 9021GQ is active - chip not in reset.
