How can I resolve a target error from Commit Flash write with PN7462 ?

I use the PN7462 microcontroller to use the NFC part and I supply it with a cr 2032 battery (220 mAH). When I try to connect it to MCUXpresso to debug my program on it, I have this error who appears :

 

following reset read of core registers failed - Ep(08). Cannot access core regs when target running.
Target error from Commit Flash write: Ep(08). Cannot access core regs when target running.
GDB stub (crt_emu_cm_redlink) terminating - GDB protocol problem: Pipe has been closed by GDB.

 

Some people say that it could be the supply current which is not sufficient but when I asked the NXP tchat, they said to me that it's not the problem, it could work with a cr2032 battery.

So, can someone could help me please ?

 

Thanks,

Louis.
