머가 문제야 도대체 ㅠㅠ


처음 nios2를 올리면 EPCS의 시작 주소부터 검색을 하는데

유효한 레지스터는 찾았으나.. EPCS 서명과 식별자도 다 맞는데

EPCS layout data가 없다고.. 근데 레이아웃 데이터는 또 머야

일단 EPCS 레지스터를 못 찾았다 에러를 보면


B.5 "No EPCS Registers Found" Error

When you run the flash programmer to program an EPCS device, you get the error:

"No EPCS registers found: tried looking at addresses...."

B.5.1 Probable Cause

The flash programmer can connect with a Nios II JTAG debug module in the FPGA, but it cannot successfully find an EPCS device located at the specified base address.

>> 플래시 프로그래머는 FPGA의 Nios II JTAG 디버그 모듈과 연결할 수 있지만, 지정된 base address에서 EPCS 장치를 발견하는데 성공하지 못했다.

B.5.2 Suggested Actions

• Reconfigure the FPGA with a valid target design via JTAG using the Intel Quartus Prime programmer. If the FPGA is configured by another method, such as by a configuration controller, the pins that connect to the EPCS device might be disabled.

>> 쿼터스 프로그래머를 이용해 JTAG으로 FPGA를 재설정하라. 만약에 FPGA가 configuration controller 와 같은 다른 방법으로 설정된다면 EPCS 장치와 연결되는 핀들이 비활성화 되었을 수 도 있다.

• If you are using quartus_pgm --nios2 from the command line, ensure you specified the correct base address for your EPCS device. You can find the flash memory's base address in Platform Designer.

>> 커맨드 라인에서 quartus_pgm --nios2 을 사용한다면, EPCS 장치에 올바른 base address가 지정되었다 확인하라. Platform Deisigner의 플래시 장치에서 base address를 찾을 수 있다.

• Ensure that the EPCS device is correctly connected to the FPGA on the board. Verify the EPCS connection by running the "Test EPCS" routine in the "Memory Test" software template provided by the Nios II EDS. If the test fails, there is a problem with your memory connection. There are two places to look for the problem:

>> EPCS가 FPGA 보드에 정상적으로 연결되었는지 확인하라. Nios II EDS에 소프트웨어 템플릿으로 제공된 "Memory Test"안의 "Test EPCS"를 실행함으로서 EPCS 연결을 확인하라.

— The physical connection on your target board

— The pin assignments on the top-level FPGA design

• Use the Intel Quartus Prime Programmer to program the EPCS device directly via a JTAG download cable, and verify that the EPCS device successfully configures the FPGA.

• Run quartus_pgm --nios2 from the command line with the --epcs parameter. This command displays information about the flash memory in the EPCS device. For more information, refer to the "Using the Flash Programmer from the Command Line" chapter.

My problem is resolved now, I just changed the clock source of the EPCS CONTROLLER. The clock was driven from the system clock using a CLOCK BRIDGE.

Now, the clock is driven from a PLL OUTPUT ( the system and the EPCS CONTROLLER clocks are now independent).

Thank you Daixiwen & dsl for helping me.
