EDS QSPI programming problem

Hi, i’m using my custom Cyclone V SoC(5cseba5u19i7n) board in combination with QSPI flash (Micron 512Mbit). 

I want to program the NOR flash via USB blaster with SoC EDS Command Shell version 15.0. 

 

When I start up the “SoC EDS Command Shell version 15.0”and type “quartus_hps.exe –c 1 –o PV ”. 

 

After programming done ,I get the following  

"1.send_access_data() error while accessing DP Register. 2.Debug Port Read Buffer reading failure, read_dp_buff() error while accessing AP Register.3.Failed to READ ACCESS to the Physical Reg. 4. Failed to read MPU Module Reset Register."  

I was wondering the JTAG was not nomally working. 

 

Thank you.

Have you found an answer to this? I am also having the same issue (5CSEBA4U) 

Except mine says "Failed to release reset register of MPU"
