JTAG connection during serial download mode

I am trying JTAG debug with i.MX8QXP MEK (Silicon Rev B0).

I can connect the debugger to the board at normal boot mode.

But, I could not connect the debugger to the board at serial download mode.

 

Does i.MX8X not support JTAG connection during serial download mode?

Because, i.MX6 is supporting JTAG connection during serial download mode.

 

Best Regards,

Kazuma Sasaki.
