Arria10SOC Dev Kit Board: Updating EPCQL1024 show “209012 Operation Failed”

We have 2pieces of Arria-10-SOC-development-kit board from Intel.

​WE tried to update the on-board EPCQL1024 flash.The detailed steps as following:

1) Switch On board's “SW4 Bit-3" as High "1", that will config FPGA as AS Mode;

2) convert *.sof to *.jic format file, Then use JTAG to burn .jic

​

Problem is : always we saw ERROR :

" 209012 Operation Failed ", never succeed to work out.

​

​

Does anyone have experience with updating the EPCQL1024 flash via JTAG on Arria10SOc board ? thanks in advance !!
